CG Cleaner/Degreaser - 1 Gallon

Have used this product for over 30 years. Biodegradable, I use it on RV, boat, metal buildings, vinyl siding, gutters, works fantastic. Removes black streaks, mildew, etc. Let it soak for for 5 ten minutes then brush or pressure wash. Use as directed, very concentrated.

I have worked in a shop environment my entire life and detailed everything imaginable. Probably the toughest out there is RV black streaks and this stuff works incredibly well. There is nothing out there that comes even close to working as good as this product as an all-purpose product. I am a customer for life.

This is great cleaning product! It is cleans everything well and be strengthened for tough jobs.

You get what you pay for : this product worked very good. Follow directions and you won't be disappointed.

This was recommended by the dealership I bought my used camper from (fiberglass sides). Removes the black streaks caused by rubber roofs and cleans extremely well. Just remember that it needs to be diluted! Read the instructions and you will be more than happy with the results!

If you could only have one cleaner this is the one you should have. There isn't anything this stuff doesn't clean! Great for carpets, car seat stains and stains on cloths, walls....What ever you have dirt on this will clean it. Won't use anything else! Buy it you will not be disappointed.

My husband swears by 4U when it comes to cleaning himself in the shower. He works on diesel generators and RVS, so he comes in covered in grease! 4U works great at ridding just about all of it!

This stuff worked Great. Removed almost all black streaks (they had been there for 2 years) on my travel trailer. Definitely worth the money. Just be careful because it can be too strong on some metals.
