Rain-X 620191 Car Wash - 100 fl oz. High-Foaming, Concentrated Formula for Greater Cleaning Action, Safely Lifting Dirt, Grime and Residues for an Exceptional Clean

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.

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.

There are better car washes out there but this one isn't bad. It cleans well enough and also makes it easier to clean later since most dust and debris rinses off before even washing. Overall I would use again and is decent for the price.

I like this product I use it to wash my cars and house outside windows. Doesn't leave residue or streaks. Highly concentrated so little bit in the bucketgoes a long way.

This Rain-X car wash soap is a great bargain. At this price point it is well worth the purchase. It provides a good amount of suds. It seems to have good cleaning power but I never allow my vehicles to get too dirty. The price for this 100 fl oz bottle size can't be beat for this quality of car was soap. This will probably be my go-to car wash soap for the foreseeable future.

Great value and good solid car soap works well even with just a bucket and hose

Works good. Nice foam and clean well

This works good on all cars that I wash for the family. The amount I need to put in the bucket is a lot but it works and looks good at the end. Smells good. Helps keep bugs off.

Very nice product.

Doesn't seem too harsh, to take of the spray on finish I use (Mothers ceramic). Rinses clean, no streaks or residue. Will buy more.

Buen producto, mucha espuma y deja un acabado brillante.

جيد مع رغوة متوسطة الكثافة
