Are magnetic glass cleaners scratch proof ?

[ColoredRock]

I have an acrylic tank and I put a Melamine foam pad on the wetside and a Microfiber towel on the dry side, so far no scratches... also dont leave it in the tank.

Just wondering if the glass cleaner I bought yesterday is scratch proof or I should not use it ? I’m just scared of damaging my glass. Thank you

Ive used most every magnet out there (current- flipper Edge and Mighty Magnets) and I find none of them are as they have the ability to trap and remain sand and even bland sand particles which are magnetic and will apply fine scratches

I agree but they can even scratch without having any particles trapped. Maybe the glass in our aquariums is cheaper than it used to be.

From my understanding, low iron glass is more expensive for the clarity but it also scratches easier.
