We have multiple pets and use this to clean up accidents. We also have three kids so, assume the worst. This product gets anything and everything up. It will even reduce old stains. We buy it by the case so we don’t ever run out.

What a special, easy, efficient product. Just spray, scrub withou water, and wow what surprise. It is super great.

Have tested and used this on all kinds of stains. Has worked excellent on all. Black grease even came out of carpet in the car. Had some stains in the house that have been cleaned a couple of times by professional carpet cleaners, buy they always came back. Used CU4 on these almost 4 months ago and still no sign of return. Only downside I see is the spray is too tight and hard too cover anything very large. Perfect for me with smaller stains here and there.

My wife HAD an odd stain on the drivers seat of her 2015 Jeep that we had tried to remove with another nationally known brand product with no luck.. While ordering a case of FW1 I saw CW4 and thought, what the heck.. It arrived, we followed the instructions and there is no more stain.. Mamma happy, everyone happy! Thanks,

This is a GREAT Product. I have used other cleaners in the past but this product is far the best. It’s application is easy, swipe with a damp terry cloth and the stain is completely lifted.
Highly recommend trying it. I use it on the Vehicles and Home when stains appear.

Used it on my vehicle’s upholstery. Don’t know if it was because of the nature of the stain, which I think is spilled coffee, but I wasn’t as impressed with it was with the vehicle cleaner and cleaning wax.

I use the CU4 carpet cleaner on my kitchen carpet….it removes dripped oily spots, iced tea stains and lots of other stains that are dripped off of dishes being loaded into the dish washer…
I also use it on my car upholstery and carpet but those are the easy stains…..
