try a scraper for removing paint off windows. its a shaped piece of plastic with a blade in it

Use a non-stick pan scouring pad. Sprinkle plain flour on tiles, and use liberal amounts of warm water on pad; scrub like crazy then wipe off gunge with a dry, lint-free cloth.Depending on the type of tile, there is a danger that a scraper will scratch them.
