Quoted from cody_chunn:

I don't see any problem at all with "cleaner waxes". As long as you don't bear down with them and use a soft applicator, you're not taking any clear off of any measurable amount in hundreds of uses (years and years).
You are over-exaggerating some products abilities to wear down top coats or damage finishes. If that were the case, there would be many. many, MANY more cars with ruined finishes from these products, as cars' finishes are in an infinitely more destructive environment and are much more aggressively polished at every use. You see classic cars all the time with original finishes that have been shined with cleaner waxes hundreds of times with like-showroom finishes still gleaming. How can that be if these products are so destructive? Answer: they aren't.
That's my opinion on cleaner waxes.
