Scratched Glass

[Spiceweasel69]

I am getting rid of my juwel 260 and need to get rid of a scratch that is 6 inches long that i can feel with my nail,but only slightly, it doesnt catch, but i can feel where it is if im not looking.

I have been told cerium oxide, toothpaste, brasso, very fine grit paper etc. Has anybody done this? I dont think that using a scratch repair on it from a windscreen repairer will work 100% as i dont want to leave any residue and make it worse.

Any suggestions?

i know dan robbins used cerium oxide

I used T Cut recently, along with a wool pad fitted to a power drill.


Took about 30 minutes to get rid of about half of the scratch.


Gave up in the end, as my back was about to snap!!

Cerium Oxide is supposed to be the best way

Wouldnt grit paper be too abrasive?

I guess theyre probably too deep to go completeley, but i at leas want to smooth them out so as they cant be seen as mych.

is it on the inside or outside? be careful what you use if its in the inside! dont want to poison any future fishy residents.

i always use toothpaste if i scrath glass (the one for teeth whiting not gel/minty ones , never tried it on an aquarium though!

Is it glass or acrylic ? if its acrylic then autosol (metal cleaner) is what you want I have used it to get rid of scratches on watch faces never tried it on Glass doubt it would work

Does depend on whether it is glass or not.

Glass - use T-cut to take the obvious depth difference out, i.e bring the scratch level with the surrounding glass, then clean it up with metal polish. The T-cut will leave small tiny scratches as it abrades away the glass, which is why you use metal polish to buff the small scratches out to a flat finish.

Toothpase works indeed spish - Used it on my phone screen last time it got scratched - left it minty fresh too!!
But i wouldnt want to use it on a big scratch coz it would take FOREVER!!

If its a scratch on acrylic I simply wouldnt touch it.... can end up doing more harm than good. Acrylic is really easy to scratch. If the tank is small and light, turn it around so the scratch is at the back.

Its a glass tank - Juwel Vision 260.

I had a go today with Tcut and toothpaste. Made some difference but not a whole lot. I guess where the tank is dry itll show up more. I hope when the tank is filled they wont be so obvious. Theyre right in the middle tho so im gonna try to do what i can. I found this:

In the link it says ideal for aquariums. Id say mine were medium scratches, not deep. Ill buy this kit and let you know how i get on. I have 4 or 5 weeks of buying things for the tank before i set it up proper.

Any other info is hugeley appreciated.

Hey I just did some scratches on a Vision 180 it was a hell of a lot of hard work! You could just feel most of the scratches but one was really bad... How the hell these were produced I will never know! Worth it though I will get some pics up later...

I used Jewelers rouge (cerium oxide) from the glass cutters £3 for a 450g bag. Quite a bit left over. Next time I will try to source some proper grit for the deeper stuff and finish with cerium I think.

I used a felt round disk on a high speed drill. Glass guy told me not to let the glass get too hot or it will crack but I thought sod it and just went for it and all seemed ok...

Never tried fixing scratches on an aquarium myself.

But the replies in here reminded me of when I was working on an IT fit out in a building and we were up against time, the guys running the fibre into the building had us making up fibre cables.

Now these have to have a perfect unblemished end.

They were made with a very fine sand paper with water on it then the ends in a die and then doing a figure of 8 motion on the end, not sure if this will help here I guess its hard to be the first to try something, but it did turn cut glass ens perfectly smooth.

Well I guees I am about to try and find a way myself.

Saw a bargain, IMHO, today and have just taken possesion of a Juwel Rio 240 + stand, Eheim 2026 Filter, heater, Upgraded lights, gravel, stones (6 large rocks) , a few fake plants for £90.

It does have a few minor scratches on the glass, I intend to spend some time getting this right before the fish go in so any updates from this thread welcome or any new contributors with successful methods appreciated.

Just had another thought as in my situation it will be a while until fish are in the tank could I use something such as HobBrite, we have a ceramic hob, to work on the scrathces then a thourough clean down of the tank afterwards.

Happy to spend time up ront getting this right.

So have been doing some more research and came upon this very long page:

If you do a search for:

Aquarium Glass Scratch Removal Idea/Experiment

Seems like another old tech like me had the same idea (use the fine sand paper for polishing fibre optic cables), unfortunately the results do not seem to have been posted.

Have you tried approaching a company that polishes stone and stuff like that. You can get grits designed for this sort of thing they rated such as 1200, 1600 2000 then after working through to the finest grit get some Jewlers rouge nothing beats this as a final polish and it is cheap enough.
