Those magnetic things absolutely suck, they dont put enough pressure on the glass to actually remove algae so you need to clean it from the inside yourself anyways

    Your magnet isn't strong enough, or maybe there's a problem with the surface of the scraper bit. Different thickness of glass requires different strength of magnets.

    Mine is too strong, I wrap the handle in cloth to increase the distance.

    My scraper takes algae very easily, but mineral deposits seems to require a blade.
