I don't think he was asking for a non abrasive polish either or claybar recommendations. Griot's Garage has a liquid spray on Paint Prep LSP remover and he's looking for something like that. Carpro Eraser recommendation 'may' do the trick. It is designed/intended to remove the polishing oils for a pre LSP smooth surface and wax removal may just happen to remove the wax too. Blackfire Paint Prep is a new product that may be spot on for your needs but I would read more into just to be on the safe side. Also a lot of people strip while washing using Chemical Guys Citrus Red a little more concentrated then usual or add a couple ounces of all purpose cleaner* to there maintenance wash soap.
*I know Pinnacle All Purpose and I think Blackfire lists that as one of its uses. SO I would just be careful/research which All Purpose Cleaner is safe for that because there could be plenty of unique formulas that aren't great for paint.
