From Koch-Chemie's technical data sheet for No Yellow Cleaner (a PDF on this page), in our words: Use it undiluted or dilute it 1:4 with water in a wash bucket, then apply it to the affected areas with a sponge or a pre-wash brush. Let it take effect and rinse off with water or a neutral shampoo. Keep it off galvanised surfaces and real wood, never use it on a hot surface or let it dry, and note that it does not remove yellowing caused by UV light. Check the sheet's warnings before first use, and where this differs from the sheet, follow the sheet.

Yes on cured clear coat at the recommended dilution, kept wet and rinsed in time. It must never touch hot glass; test aftermarket tint.
