Rain-X Waterless Car Wash Review + How to Save Money

Rain-X Waterless Car WashFor many years, I’ve used Rain-X Rain Repellent to keep my windshield clean. Why not try their Rain-X Waterless Car Wash?

From experience, I already knew that Rain-X worked well at repelling water and keeping my windows cleaner for longer. (I love watching the water bead up on the window and roll away.) In addition, I could use the spray without worrying about leaving streaks on the windows.

This is a big reason why we use waterless car wash products anyway, right?

How Does Rain-X Work to Clean Cars – Without Water?

Just like other spray-on car washes, Rain-X doesn’t require water in order to clean your vehicle. You simply spray it on and wipe it off in a single step (or maybe that’s 2 steps).

The highly-lubricated formula helps lift dirt, dust and debris from the surface of your car. Therefore, you don’t have to worry about scratching your car’s finish.

In addition, this product contains Rain-X’s own water repelling technology that I talked about above. This provides an extra layer of protection for your car’s finish, plus it repels water at the same time.

Note: Many people report a glossy shine and a “smooth-to-the-touch” finish after using Rain-X car wash. Some users also apply it to plastic trim pieces to help enhance their shine as well. They also recommend switching to the glass cleaner for glass surfaces.

Similar to their glass cleaner, you don’t need to buff off this product like you’d need to do with carnauba wax. Quite the contrary, in fact.

You can spend a fraction of the time washing your car, and you can complete the job in less steps. Not to mention, waterless car wash products require minimal elbow grease, so car washing actually becomes enjoyable. =)

He mentions that he used the Meguiar’s Ultimate Waterless Wash on his wheels, and he likes that product as well.

What’s the Cost of Rain-X Waterless Wash? Can You Save Money?

According to my calculation, an $18, 32-ounce bottle can give you approximately 8 car washes. That’s assuming you use the average 4 ounces of cleaner per wash, which will cost about $2.25.

If you own a smaller vehicle or a motorcycle, the spray bottle will obviously last longer. On the other hand, if you use a heavy hand with the sprayer, you’ll go through the bottle faster.

From my experience, a small amount of Rain-X Waterless Car Wash can go a long way. This is partly due to the design of the spray nozzle, which lets out a fine, even mist. In other words, you can use less product while covering a larger surface area. Brilliant!

Rain-X Waterless Car Wash Ingredients:

I find that microfiber towels play a very important role in car washing. First, they virtually magnetize dirt and dust away from the item you’re cleaning. Second, they work really well at absorbing moisture quickly.

Therefore, you don’t have to worry so much about leaving streaks or fiber particles on your newly cleaned bright shiny car. I mean, who wants that?
