## Description

Keep your vehicle in pristine condition with Rain-X Foaming Car Wash. Rain‑X Foaming Car Wash visibly reduces spots and streaks for a high gloss finish. The high-foaming formula is concentrated for greater cleaning action. Rain‑X Foaming car wash safely lifts dirt, grime and residues caused by rain, sleet, and snow leaving your vehicle with a brilliant finish! This product also protects waxed surfaces and is biodegradable. For the last 50 years, Rain‑X has provided drivers with products to help them outsmart the elements. All Rain‑X products are designed to help keep our customers a confident step ahead of Mother Nature on the road. For best results avoid washing the car in direct sunlight. Application Instructions - first hose off heavy dirt and debris from the vehicle, then add 1oz of Rain-X Foaming Car Wash to an empty bucket and fill up the bucket with a hose. Start at the top of the vehicle and apply soapy water to a portion of the vehicle's surface using a clean wash mitt, sponge or 100% cotton cloth. Rinse off with clear water and dry with a chamois or 100% cotton cloth.

Review: Effective Cleaning with Minimal Effort - Finding a car wash soap that balances strong cleaning power with a gentle touch on the paint is essential for regular maintenance. This 100 fl oz bottle of Rain-X Foaming Car Wash provides a high-volume solution that works well for both bucket washing and foam cannon applications. The concentrated formula ensures that a small amount goes a long way, making it a practical choice for keeping a vehicle looking its best. Performance and Results High-Foaming Action: The soap creates a thick, rich lather that clings to the surface of the car. This helps to loosen and lift away road grime, bird droppings, and dust without the need for aggressive scrubbing that could cause swirls in the clear coat. Safe for Finishes: It is formulated to be tough on dirt but safe for wax and sealant layers. You can use it for weekly washes without worrying about stripping away existing protection. Streak-Free Shine: After rinsing, the formula helps the water sheet off the panels, which reduces the amount of drying time needed and helps prevent water spots. The result is a clean, reflective finish that looks professional. Exceptional Value: The large 100-ounce container offers many washes per bottle. Because it is highly concentrated, it provides a much lower cost per wash than smaller, premium-branded alternatives. Final Thoughts This car wash is a dependable staple for any home detailing kit. It performs consistently on various types of residue and leaves the exterior looking refreshed. For anyone looking for a high-quality, high-foaming soap that handles the heavy lifting of car cleaning safely, this is an excellent selection.
Review: Sudsy Power That Gets the Job Done - Sudsy Power That Gets the Job Done I’ve been using the Rain-X Foaming Car Wash for a couple of weeks now, and I have to say it really surprised me. The first thing I noticed was how little product I needed—just a couple of ounces in a bucket and it produced a rich, thick foam that clung to the car well. It lifts off dirt and road grime without much scrubbing, which makes washing faster and less tiring. The cleaning action is strong enough that my car looked noticeably shinier after rinsing and drying, almost like a light wax effect, even though this is just a wash. I liked that it didn’t leave streaks or water spots when I rinsed thoroughly, which is something that can be an issue with cheaper soaps. One thing to keep in mind: it’s quite concentrated, so using too much can make it harder to rinse off. Stick to the recommended dilution and you’ll be fine. Also, while it does a good job on everyday dirt and dust, for stuck-on bug splatter or heavy road tar, I still needed a separate cleaner. Bottom line: A great value car wash soap that foams up nicely, cleans effectively, and leaves the car looking bright and fresh. Just don’t overuse it, and you’ll get professional-looking results at home.

## Questions & Answers

**Q: I've just bought a sun joe spx3001 2030 psi 1.76 gpm 14.5 amp electric pressure washer. how do i dilute it before i pour it into the deternent tank?**
A: Yes put 3/4 soap 1/4 water

**Q: I just got a new electric power washer. Can this car wash be used in it? Anyone know?**
A: Just be aware.  I used this in my electric power washer after running through a "washer tank" full of dish washing liquid.  The rain-x left the car much more "spot free" however, it blew through my power washer literally 10 times faster than dish washing liquid.  Is it very very thin so you will suck the entire contents down crazy fast.

**Q: black cars results**
A: I used this product on my last car (black) and continue to use it on my new car (black) … great results, great product.

**Q: Does this contain sodium chloride (Salt)?**
A: No

### ⭐⭐⭐⭐ Nice Car Wash Soap. I Wish it Was More Foamy. No Residue Left Behind
*by P***R on March 11, 2026*

This was the same brand of car wash my dad used when we were kids. So I was excited to buy it. It comes in a nice thick gel, pretty green color. But I have definitely used car wash products that are more foamy. People love foam and suds. It makes them feel like they are getting their car cleaner. But, it did a really good job cleaning the cars, rinsed off no problem and didn't leave a soapy residue. I would buy again.
