paint cleaners are basically just a polish, they can have abrasive in it or they just work chemically , they are used after the claying and before any wax or glaze, if your using a machine polisher with a polish it would take the place of a paint cleaner (something like menzerna IP polish) a glaze is known as a few things, which glaze you thinking, most glazes are very very fine polishes that finish a polishing job just before you protect with a sealant then a wax (or whichever final finish product you choose)
