Using ON OFF on Awlgrip
Is it safe to use ON OFF on Awlgrip. I have a very dirty waterline with algae and scum and scale.
Last year I scrubbed scraped and sweated trying bleach and vinegar. Finally in desperation I tried ON OFF which shifted it like magic. Brush on wash off job done.
Now I read that it damages Awlgrip but how bad is the damage? Can it be any worse than the mechanical damage I would do by rubbing and scrubbing and scraping?
