I don't think ONR or any other solution out there which demands scrubbing a sponge, micro fibers or whatever over the paint is considered safe, at some stage, or if you do it wrongly you will scratch your paint !..
I am planning from now on to wash my car myself with water pressure and possibly snow foaming (since i got coating installed professionally for me) then I will use ONR as a waterless/drying aid ONLY after this to dry the car and minimize scratches and swirls, i really never trusted the standard sponge or ONR announces the use of the Big Red Sponge to wipe off dirt and filth of your car paint, you WILL be dragging that dirt across your paint and WILL cause some sort of scratches I believe...
good luck,
While that is true, Rinsless washes are even safer than a traditional 2 bucket wash if done correctly.
I use a total of 12 towels to do my rinsless wash

10 in the solution bucket and 2 drying towels. This way, once a towel side has touched a dirty panel it never touches the paint again. This is in comparison to the two bucket wash method which would require you to use a grit guard - while safe, its still not as safe as multiple towels when using rinseless.
Look up the Gary Dean method of rinseless washes.
I was so skeptical of trying rinseless washes - but since I started a month ago, this is all I do. Call me converted. Plus, you dont need to drag out a hose, pressure washers, buckets etc. One bucket filled halfway (2gallons) with you towels is all you need

I save the pressure washer etc. for once a month deep cleans only.
P.S. If you scrub the paint with your wash media as you describe - its already a stupid move. All you do is a light pass with the media - Never scrub.....I completely agree with the big red sponge method being a little unsafe as the same sponge is reintroduced to the paint. However, using multiple plush towels loaded with solution will not cause a problem. All you do is one
LIGHT pass (not SCRUB) - the solution traps the dirt and lifts it. Your towel picks it up. You then turn over to a fresh side and continue. In my one month of doing this - I have not noticed even a single hairline scratch on my soft Honda paint. Do it right, and you can go a long long time without any swirls and scratches :xyxthumbs:
As stated before, foaming or pressure washing will release loose dirt. It will not touch the embedded dirt that has attached itself to your paint.
Some form of agitation with a lubricated solution is needed. Then you can follow with ONR as a drying aid.
Your steps are missing a crucial step (bold and underlined ^ )
Therefore: I still find your method will cause swirls. Just my opinion but you wont know till you try lol.
I would suggest multiple towels if you plan on using waterless wash. This is the only way you can minimize scratches and swirls. Mist your panel and wipe, and then turn over to a fresh side. Never touch the paint with a side that has been used to wipe the dirty paint. Using this method with your pressure rinse and foam will yield far better results
