I can't think of anything that I don't like about GS. I tried P & S interior and didn't like that at all. But this GS is just about perfect. It doesn't leave that sticky feeling like the P & S did. P & S also turned some black plastics white on me. GS has not and leaves the surfaces feeling clean and new. It has almost no smell which I like a lot. I don't get excited about it as a prewash like other people do but for engine bays, bugs, interiors, etc. it is fantastic. It is very versatile which is nice because it keeps the number of products needed to detail lower. Although some days the list of products seems endless regardless. I have purchased some of the other Koch products and am looking forward to using those also.

I bought this product from many detailers saying it’s good for cleaning everything, it foams nice after just 5 ounces of product and 20 ounces of water, there’s not much smell to it there’s shine if your using it as a pre-wash, it works great for leather,plastic, rubber. I would highly recommend as all purpose cleaner!

Can be used on so many surfaces and does a great job… for the dilution ratio it is very economical and that makes it even better

Awesome Multi Purpose Cleaner

Great product! Works well and will definitely be purchasing again
