This may be a dumb question, but I'd love to see someone test the actual cleaning ability of a rinseless wash (especially when used as a presoak) to determine if one actually cleans better than another.
If you presoak a section with D114, presoak a section with N-914, and presoak a section with ONR (all at waterless wash ratio). Waited a few minutes for the presoak to start breaking down the dirt, then proceeded to pressure washed them off the paint, would one actually be a better cleaner than another?
We know some car soaps when foamed onto a vehicle provide a good amount of cleaning ability while other soaps are virtually useless as a presoak. I am just curious if there is actually a measurable difference in the cleaning ability of our favorite rinseless washes.
What I really want to know is if D114 & N-914 actually CLEAN more than other rinseless washes OR do we just say they are "better cleaners" because they are more concentrated and don't leave any gloss enhancers, silicones, or waxes behind & therefore technically leaving the paint "cleaner".
