Does clay bars also take old wax/ sealants off

[Alex Haramic]

Looking at cleaners that take off old wax and sealants I noticed clay bars are offered to does that mean it will strip the old wax or sealant of too I know there are non abrasive polishers such as pinnacle and Wolfgang paint cleaners then there are spray waxes I know the difference between the two but I was wondering if clay bars do the same ? Or just pick up particles that are in the paint that some cleaners can't pick up? Thanks
