It is hardly the only way to clean a cartridge, therefore, until matters are cleared up to a sufficient degree, I would not use something that can be the cause of so much problems.
It is not just the deposits I would worry about. I would worry about the application of force pulling down on the cantilever when one is lifting the stylus out of the cleaning pad. This direction of force is unnatural and it may damage the cartridge. I know of two people who pulled the cantilever out of very delicate MC cartridges using this kind of cleaner. Perhaps they raised the arm too fast, thereby applying excessive force, but, in any case, I would not risk damaging a cartridge this way.
