What is a car wash fundraiser

A car wash fundraiser is an event where volunteers wash cars in exchange for donations or a set price, with all proceeds going toward supporting a school, club, or student group. Most school car wash fundraisers are run by PTSAs, PTOs, booster clubs, or student organizations.

These events are typically held outdoors on weekends and rely on volunteer labor rather than paid services. Because expenses are low, most of the money raised goes directly to the cause, such as supporting an in school STEM lab on campus.

Car wash fundraisers are especially popular for elementary and middle schools because they are family friendly and easy for students to help with age appropriate roles.

Why car wash fundraisers work so well for schools

Car wash fundraisers continue to be popular because they check many boxes for busy school communities. They are relatively low cost to run compared to product based fundraisers, easy to explain and promote, and highly visible to the local community. Schools also like that they can scale the event up or down depending on volunteer availability and fundraising goals.

Another benefit is that supporters immediately understand the value. Instead of selling items or asking for donations without much context, families receive a useful service while knowing their contribution directly supports a school they care about.

How to run a successful car wash fundraiser

Planning and permissions

Start by choosing a date and confirming any permissions you may need. Some schools require internal approval forms, and many cities, churches, or local businesses require permission to use their parking lots. It is also worth checking whether insurance coverage is required and what rules apply to water use and drainage. Taking care of these details early helps avoid last minute issues or cancellations.

Choosing a location

Location plays a big role in turnout, and high visibility areas tend to perform best. School parking lots, local churches, community centers, or business parking lots with permission are all common options. When choosing a spot, look for a location with steady traffic, clear signage visibility, and safe entry and exit points for vehicles.

Supplies you will need

Car wash fundraiser supplies are generally simple and affordable, and many groups already have access to most of what they need. Buckets, hoses, car wash soap, sponges, towels, and signs are usually enough to get started. It also helps to have sunscreen and drinking water available for volunteers, especially during warmer months. Bringing extra towels and supplies can make the day run more smoothly if turnout is higher than expected.

Setting prices and donation options

Many groups choose to ask for a suggested donation rather than setting a fixed price. This approach gives supporters flexibility and often leads to higher average donations. Some schools also offer flat price washes, pay what you can options, or bundled pricing for families with multiple vehicles. Accepting digital payments alongside cash can make it easier for people to donate on the spot and helps avoid missed opportunities.

Car wash fundraiser ideas to raise more money

A few small additions can make a noticeable difference in how much your car wash fundraiser brings in. Simple extras like selling snacks or drinks while cars wait can add easy revenue without much additional planning. Some groups also offer a deluxe wash option for a slightly higher donation, which gives supporters a choice while increasing the average contribution.

Partnering with a local business for matching donations can also boost results and strengthen community ties. Playing music and creating a fun, upbeat atmosphere helps draw attention and makes the event feel more like a community gathering than a chore. Small upgrades like these can make the fundraiser more memorable and more profitable at the same time.

Flyers, signs, and promotion tips

Promotion often makes the difference between a slow day and a successful car wash fundraiser. Clear, simple messaging helps families know exactly when and where to show up and why the event matters.

Sending car wash fundraiser flyers home with students is still one of the most effective ways to reach families, especially when paired with reminders in school newsletters.

Posting signs near the event location helps capture drive by traffic on the day of the fundraiser, while sharing digital flyers on social media extends your reach beyond the school community.

No matter how you promote the event, make sure all materials clearly list the date, time, location, and what the fundraiser is supporting so supporters feel confident stopping by.

How much money can a car wash fundraiser make

How much money a car wash fundraiser raises depends on factors like location, turnout, and how well the event is promoted. Many school groups raise anywhere from a few hundred to a few thousand dollars in a single day, especially when the fundraiser is planned around peak traffic times.

Groups tend to see better results when the event is clearly promoted ahead of time, volunteers are organized and ready to keep cars moving, and digital payment options are available in addition to cash.

Choosing a location with steady drive by traffic also makes a noticeable difference. While results vary from school to school, car wash fundraisers generally offer a strong return for the time and effort invested.

Fundraising with All Things Science

Schools can also partner with organizations like All Things Science to help increase student participation in enrichment programs by offering fundraising prizes that include free admission to after-school STEM programs, in-school labs, and summer camps.

A well organized fundraiser can bring the school community together while helping more students take part in enrichment programs.
