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, Greg on Jan 23rd 2018
This cleaner works amazing, does not leave a greasy reside! Best I have used. I recieved the order very quickly! Unknown on Jan 9th 2018
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. Doug on Jun 6th 2017
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. Mr. Biggs on Dec 29th 2016
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..... Jodie P on Sep 11th 2016
