Optimum Opti Clean

So would it be better to just go with ONR on even a heavily soiled car or do a touchless car wash first to get some of the grime off then do a ONR wash in the garage? I used a touchless last winter then dried with MF's.

 

To reduce the chance of marring, try to rinse off with a hose, self-serve wash, or touchless then do ONR.

 

OOC was intended as a true spray and wipe. Some of the reviews I have read tell of the poster soaking the panel and using a whole bottle on a single car. This is simply not necessary. Prime the MF with water or OOC, mist the panel with a fine mist (not dripping), let soak a few seconds and wipe slowly in a single direction. Flip the towel and make another pass if necessary and lightly buff with a plush MF as you would a QD or spray wax.

If you prefer to soak the to the point of dripping, just to feel safe in your mind, you can dilute OOC further to 5:1 without any negative effects. This concentration still has way more actives than any of the competitors waterless washes and remains super safe. I was involved in the testing process and have as much experience with it as just about anyone.
