So, my last AG order included two waterless wash products Ultima WW and Optimum Opti Clean. Usually I do 2 bucket washes, occasionally an ONR wash. Whenever I use ONR I always foam and rinse prior with a pressure washer. This does kind of defeat the whole point, but I do it because I have the products and facilities. Also, most filth and grime comes off this way and the towels stay very clean and you use less of them. I pressure wash outside, then ONR inside. I did the same thing with Ultima WW and Opti Clean as waterless washes (so to speak). Both products were excellent and it took me only 2 hours to do my Pathfinder including clean wheels and dress trim. Conventional washes take me close to 3, as I go slow and take every precaution. The thing is, I just can't believe how slick and what a good job Ultima WW does with only a half ounce in 22 ounces of water. It's so amazing and cost effective. This stuff glows with slickness, it's like applying a sealant. The Optimum is also excellent, but requires so much more product to make your dilution. It's hard to pick a clear winner on performance, also, they both smell like a janitors closet. However, by price ULTIMA clearly rules. I was so amazed by this stuff, the towel just glides over the paint. You only need like 1 or 2 sprays per panel. How does Ultima blow everyone away with there dilution ratio? I will never buy a quick detailer again. This stuff is slicker and glossier than any of them. If it wasn't for Corey's review , I never would have tried this stuff, because I wouldn't believe it could work at this dilution ratio. So, thank you for that. Bottom line, truck looks cleaner and glossier than with a conventional wash. This stuff is do slick, I can't see how you could instill any scratches using it unless what you are washing is filthy. Now I want to check out other Ultima products, but I've already have so much of other stuff I'll have to wait. Everyone should have this stuff in there collection for a quick detailer, waterless wash, rinse less wash, and clay lube. It's just wonderful stuff!
