A car wash is one of the most hands-on ways to raise funds for your school or club. It’s low-cost to run, gets everyone involved, and can bring in a surprising amount of money in just one afternoon—especially if you’ve got a solid plan (and enough towels).

If your PTA is considering a car wash fundraiser, this guide covers everything you need to know—from what supplies you’ll need to fun ways to boost revenue without washing cars all day long.

🚗 What is a Car Wash Fundraiser?

A car wash fundraiser is a fun, active event where volunteers (usually students, parents, or both) wash cars in exchange for donations or a set fee. It’s typically held in a high-traffic parking lot—like a school, church, or business—where drivers can stop in for a quick clean while supporting a good cause.

Guests drive up, hand over a donation or ticket, and volunteers do a basic exterior wash—sometimes with a few extras like drying, windows, or even tire shine if you’re feeling fancy.

It’s one of the most straightforward fundraisers out there, and it doubles as a community event—cars get clean, kids get involved, and your school earns some easy funds. Win-win-win.

💸 How Much Does It Cost to Run?

Good news—car wash fundraisers are one of the cheapest events you can organize, especially if you can borrow supplies and secure a free location. Most of your expenses will come from basic cleaning materials and a few signs to catch the attention of passing traffic.

Here’s what you might need:

• Car wash soap (you’ll need more than you think!)
• Sponges and scrub brushes
• Buckets
• Towels and microfiber cloths for drying
• Access to water and hoses (make sure there’s enough pressure!)
• Traffic cones or ropes to guide cars
• Posters or signs for promotion
• Gloves (optional, but helpful for volunteers)
• Garbage bags and cleanup supplies

To save money:

• Ask families to donate supplies or bring extras from home
• Check with local auto shops—they might donate items or sponsor the event
• Look into whether the school or district already has event signage or cones
• Use washable poster boards so you can reuse them next year

If your school charges for water usage or requires a permit to use the property, include those in your budget planning. In some places, you may also need to check local regulations about water runoff or environmental restrictions—just to be safe!

With some smart planning and a little community support, most car wash fundraisers can be pulled off with minimal upfront cost and a great return.

📍 How to Pick the Right Location

The perfect car wash spot is all about visibility, safety, and water access. You want somewhere that’s easy to find, gets a decent amount of traffic, and has enough space for cars to queue up without causing chaos.

Here are a few popular location options:

• School parking lot – Convenient, familiar, and often free to use. Just check with administration and custodial staff in advance.
• Church or community center lot – Great for weekend events and usually open to partnering with local groups.
• Local business lot – Gas stations, auto parts stores, and even fast-food spots may let you use part of their lot in exchange for a shoutout or signage at the event.
• Park-and-ride or commuter lots – If you time it right, you might catch drivers looking for a quick car wash after work or before errands.

Things to consider:

• Water access – Is there a working hose hookup nearby?
• Drainage – Avoid locations where water will pool or cause mud puddles.
• Restrooms – Will volunteers have access to one nearby?
• Visibility – Can drivers see your signs from the road?
• Permission – Always get written permission or a permit if required, especially if you’re using a public or business-owned lot.

Pro tip: Try to plan for a spot where you can direct traffic in one way and out another. This helps keep things safe and avoids traffic jams—especially if your crew includes younger helpers with very enthusiastic hoses.

🎯 Setting Your Fundraising Goal

Before the first sponge hits a windshield, it helps to know what you’re aiming for. Setting a clear fundraising goal gives your team direction—and makes it easier to plan how many cars you’ll need to wash, how many volunteers you’ll need, and whether to add any extra money-makers (like a bake sale or raffle table).

Start by asking:

• What are we raising money for?
• How much do we realistically want (or need) to raise?
• How many cars can we expect over a 3–4 hour window?

Let’s say your goal is to raise $1,000. If you charge $10 per car, you’d need to wash 100 cars. That’s totally doable with a good turnout and a few “donation heroes” who throw in $20 or more just to support the school.

💡 Tip: Many schools skip a set price altogether and just ask for donations. You’ll be surprised how generous people are when they know it’s going to a good cause—and not having a set price makes it more inclusive for families on a budget.

Also keep in mind:

• The weather plays a big role—have a backup date or rain plan
• You can boost earnings with add-ons (more on that coming!)
• Pre-selling car wash tickets can help you hit part of your goal before the event even begins

Whether you’re trying to fund new sports gear or classroom tech, a solid goal helps the whole team stay motivated (and makes those wet sneakers feel worth it).

🧾 Setting a Budget Without Getting Soaked

Car wash fundraisers are famously low-cost, but a little budgeting goes a long way in making sure you don’t accidentally spend more than you raise. The goal? Keep expenses minimal and let the majority of the money go straight to your cause.

Here’s what you might include in your car wash budget:

• Soap & cleaning supplies – car wash soap, sponges, brushes, buckets
• Towels & drying cloths – microfiber ones work best (ask around for donations!)
• Sign materials – poster boards, markers, or printed signs
• Hose connectors or splitters – especially if you’re using multiple hoses
• Gloves – optional, but helpful for keeping hands happy during long shifts
• Snacks/water for volunteers – keep your crew hydrated and energized
• Permits or fees – if required by the school, city, or property owner

🎯 Goal: Try to keep your costs under 10–15% of your fundraising goal. If you’re aiming to raise $1,000, stick to around $100–$150 in expenses max.

Cost-cutting tips:

• Ask families or staff to donate supplies (especially towels and buckets)
• Partner with a local car wash or auto parts store—they may donate soap or lend equipment in exchange for a shoutout
• Reuse signs and supplies for future car washes (pro tip: laminate signs so they don’t wilt in the sun or splash zone)

A little prep goes a long way—plan smart, spend light, and you’ll make a tidy profit even before the last car drives off shiny and clean!

🙌 How to Recruit Volunteers and Organize Shifts (Without Begging)

A car wash fundraiser is a team sport, and the more hands you have on deck, the smoother (and more fun) it’ll be. The key is to keep roles simple, shifts short, and volunteers happy!

Here’s who you’ll need:

• Sign holders – waving signs near the road to draw in traffic
• Greeters – welcoming drivers, collecting donations or tickets
• Wash crew – soaping, scrubbing, rinsing (expect to get wet!)
• Drying team – drying off cars quickly so there’s no water spots
• Supply manager – keeps soap buckets filled and towels rotating
• Floaters – flexible helpers who can jump in wherever needed
• Supervisor/adult lead – keeps things moving and ensures safety

🕒 Organizing shifts:
Break the day into 1–2 hour shifts so no one gets burnt out (literally or figuratively). Create a signup sheet (Google Sheets or Signup Genius works great), and be sure to leave space for backup volunteers in case someone cancels last-minute.

📢 Recruiting tips:

• Ask teachers to help recruit student volunteers—especially middle schoolers and high schoolers who need service hours
• Send out a fun “Get Soaked for a Cause!” email or flyer
• Offer little incentives like a free snack table, cold drinks, or even a silly “Top Sponge” award
• Make it social—let kids sign up in pairs or small groups so it feels more like a hangout than a chore

And don’t forget: music makes everything better. Bring a speaker and blast a feel-good playlist to keep energy up (and volunteers dancing between cars).

📣 How to Promote the Car Wash Fundraiser (and Get a Line Around the Lot)

You’ve got the soap, the sponges, and a team ready to roll—now you just need a steady stream of dirty cars! Promotion is key, and luckily, a car wash is one of the easiest events to advertise because it’s fun, visual, and totally community-friendly.

Here are some tried-and-true ways to spread the word:

✏️ Before the Event:

• Backpack flyers – Send a flyer home with students a week or two ahead
• School newsletter or app – Add it to the weekly update with all the details
• Social media – Post on the school’s Facebook page, local community groups, and Instagram with pics, countdowns, and reminders
• Printable posters – Hang them at school entrances, nearby businesses, and community bulletin boards
• Local businesses – Ask if they’ll post a flyer in their window or share it on their socials

🪧 On the Day of the Event:

• Big, bold signs near the road – Make them colorful and legible from a distance (and make sure volunteers are holding them with enthusiasm!)
• Arrows to guide traffic – Once cars turn in, make it clear where to go
• Balloons or streamers – These help draw attention and add a festive feel
• Music and waving kids – Nothing says “FUN EVENT HERE” like a group of kids in bright shirts dancing and waving signs at traffic

💬 Messaging tip: Keep your message short and clear:

“Car Wash Fundraiser – This Saturday 10AM–2PM – [School Name] Parking Lot – Donations Welcome!”

And don’t forget to hype up what the fundraiser supports (new equipment, field trips, classroom tools, etc.). People love knowing their money is going toward something great for the kids!

💰 How to Price the Wash (or Ask for Donations)

When it comes to car wash pricing, you’ve got two main options: set prices or donation-based. Both work—so it really depends on your crowd and your goal.

💵 Option 1: Set Prices

Flat rates make it simple and quick at the donation table. Here’s what most PTA-style events charge:

• $5–$10 for a basic wash
• $12–$15 for a deluxe wash (add drying, windows, or tire shine)

If you go this route, offer a clear menu on your signs so people know what they’re paying for. Bonus: You can also pre-sell car wash vouchers at school to lock in some income ahead of time!

🧼 Option 2: Donations Welcome

This is super popular with school groups—it feels more casual and often brings in more than a set fee would. Many folks will give $10, $20, or even more when they know it’s supporting a good cause (especially if students are working hard and smiling through the suds).

💡 Pro tip: If you’re doing donation-only, suggest a “recommended donation” on your signs (like: “Suggested: $10 per wash”) so people have a ballpark.

And no matter which option you choose:

• Have a secure cash box and a card reader if possible (Venmo or PayPal QR codes work too!)
• Keep small bills on hand to make change
• Offer a donation jar near the drying station—some people give extra as they drive off!

💡 Fun Ways to Increase Revenue (While the Cars Get Soapy)

The car wash itself will bring in solid funds—but with a few clever extras, you can seriously level up your total without washing a single extra car.

Here are some creative, easy add-ons that work great with a car wash setup:

🍪 1. Bake Sale Table

Set up a bake sale table with cookies, brownies, or individually wrapped treats (store-bought or homemade). While folks wait for their car—or as a thank-you grab—it’s an easy sell. Keep prices low ($1–$2) and display everything neatly.

🧺 2. Bucket Raffle

Yes, you can totally run a mini raffle on-site! Display a few donated prize baskets (think: movie night, self-care, gardening, etc.) and let guests buy raffle tickets at the donation table. It adds an extra element of fun, especially while people wait in line.

🧃 3. Cold Drinks for Sale

Stock up on bottled water, juice boxes, or soda in a cooler. On a sunny day, people will happily grab a cold drink for $1–$2 while they wait.

🧽 4. “Super Clean” Upgrades

Offer optional upgrades for an extra donation:

• Tire shine
• Interior vacuuming (if you have the gear)
• Air freshener spritz
  Even if only a few people opt in, it adds up fast!

🎟️ 5. Pre-Sell Wash Vouchers

Sell car wash vouchers in the week leading up to the event—perfect for families who want to support but can’t attend that day. Plus, pre-sales give you some guaranteed income in case it rains (because: weather!).

💼 6. Sponsor Shoutouts

Ask local businesses to sponsor your event in exchange for a sign at the car wash. “Today’s event is brought to you by Joe’s Auto Repair!” Print out a few signs and pop them around the site—it’s easy money for a little exposure.

📸 7. Photo Opp Corner

Set up a quick “We Got Washed!” sign or photo backdrop. Families love snapping a pic of the kids holding sponges or posing with a clean car. Add a donation jar nearby—some will drop in a few extra bucks for the memory.

These extras not only raise more money—they also create a lively, fun atmosphere that turns your fundraiser into a mini community event.

🗓️ What to Do on the Day (To Keep Things Moving and Morale High)

The big day is here! To keep your car wash running smoothly (and avoid a traffic jam in the parking lot), a little prep goes a long way. Here’s what to focus on to keep everyone happy, safe, and mostly dry.

✅ Morning Setup Checklist:

• Arrive early to set up stations: wash, rinse, dry, signs, donation table
• Check water pressure, hose connections, and soap buckets
• Assign volunteers to their stations and walk through the “car flow”
• Put up big, clear signage by the road and at the entrance
• Set up any extras (bake sale, raffle table, cooler for drinks)
• Crank up the music—it sets the tone!

🚙 Car Flow Tips:

• Use cones or chalk to guide cars in and out
• Designate one person as “traffic coordinator”
• Keep it one-way if possible (in one side, out the other)
• Have a greeter explain the process and collect donations right away

🧽 Volunteer Tips:

• Rotate jobs every 45–60 minutes if it’s a long day
• Keep cold water and snacks available for volunteers
• Provide gloves and sunscreen if needed
• Encourage energy with music, cheering, or a “Car of the Hour” award

🌧️ Weather Backup Plan:

• Have a rain date set (and clearly communicated ahead of time)
• If it’s just a light drizzle, you might be able to push through—just keep safety first
• If rescheduling isn’t possible, turn it into a voucher pickup day!

Don’t forget to take pictures throughout the event—it’s a great way to promote future fundraisers, thank volunteers, and show families what a great day they helped support.

💌 How to Thank Everyone Involved (And Make Them Want to Help Again)

You’ve scrubbed, rinsed, and dried your way to a successful fundraiser—but don’t skip the most important part: thanking the people who made it happen! Volunteers, donors, and supporters all gave their time, energy, or money—and a little appreciation goes a long way.

Here’s how to spread the love after the event:

• Send a thank-you email or text blast – Include how much was raised, fun highlights, and a few photos from the day.
• Post on social media – Give shoutouts to volunteers, sponsors, and everyone who showed up. Tag local businesses that supported you!
• Print or create digital thank-you cards – Especially for business sponsors or teachers who helped organize.
• Create a photo collage or bulletin board at school – Show off the fun and the teamwork!
• Have students make handmade thank-you notes – This is always a hit with parents and staff. Even a few scribbled “Thank you for helping!” notes with sponge doodles = instant smiles.
• Feature top helpers in the school newsletter – Give them a little spotlight moment—they earned it.

And don’t forget to thank the car owners! A sign at the exit saying, “Thanks for your support!” or a small flyer on their dashboard showing what the fundraiser supported is a sweet touch.

Ending on a high note makes your PTA look organized, thoughtful, and fun to work with—exactly the kind of energy that keeps momentum going for the next fundraiser on the calendar.
