I really enjoy rinseless washing and normally rinselss wash my car once a week. I currently have ONR and Koch Chemie RRW. These seem to work well but I'm just curious what other people's go to rinselss is.
which they then clarified when i asked whether that meant days or weeks:Rrw leave a light protection on the surface for a short time
I would say just some days. It is not like a sealant or coating.
