Is it safe to use as a prewash on ceramic coated vehicles?

TMH123, Yes you can use it as a prewash on a good quality coating. 8:1 dilution in a bottle or you can run it through a foam cannon- 30 ml in the cannon is plenty. Completely dependent on how good and which type your coating is however. @scwdetail

Is this clear coat safe? Just in case I get over spray on wheels while cleaning tires

When diluted it is safe on clear coat

I have a question what dilution sure would you recommend just after going through snow on tires and wheels wells

Usually for exterior and wheels a 1:5 dilution, but is extremely dirty a 1:1 could be good, especially since it’s very cost effective

What’s the strongest dilution ratio safe on car paint?

1 part GS to 5 parts water is safe for paint.
