Glass Polisher

[weisoon]

Anyone knows how to remove scratch on a glass? Its a straight line single scratch. Any polisher to recommend? Hope will not cause more fine line scratches then the single line scratch if using the polisher.

Weisoon,

Apparently there are glass polishing kits available - just read about this browsing TFH at MPH this afternoon...but no mention of brand or where to get! Most likely it will be quite hard to find in S'pore (as a lot of DIY things are) so best to search overseas. If you find, get me one OK? want to try it on some rather irritating scratches on the front glass of a small tank I just bought!!

Will try to do some search on the web at the mean time and will keep you updated.

think someone asked this before...

it depends how bad is the scratch.. but small scratches can be polished off using some toothpaste, moderate ones can try autosol, heavy ones have to import some kinda special stuff from overseas.

reason why toothpaste and autosol might work is that they are slightly abrasive, so it actually "grinds" down the area around the scratch thereby smoothing it out... which actually at the same time will weaken your glass ever so slightly.. so don't over do it (hm.. is it possible to overdo it??)

Anyway really no harm trying lah.. how much damage can toothpaste do.. haha..

No problem in trying them out. But my main worry is that with the polishing disc, instead of removing the single scratch line, end up with a patch of multiple very fine scratch lines. Hope you know what I am trying to describe. Maybe will try it out when I have the time on a piece of unwanted glass. I actually bought some stuff from Germany for polishing acrylic. Should be able to apply to glass as well. Just that need to find time to try it out.

Weisoon, for glass polishing can look for Cerium Oxide. We used it at the final polishing stage for our telescope mirrors.

Can get from USA.

what if the scratches are inside the tank? Is it possible to remove them.. I have a lot of small scratches due to excessive scrubbing of algae.. : D

If inside then good luck must drain off the water and polish the interior.

The tool I bought is a small power tool with speed adjustment and universal adapter for fitting bits. The range by this German brand : Pro***n is much more than a particular USA brand Dr***l. Just have to try it out.
