    Not quite for aquarium use, but I have a tricky problem that I'm hoping someone can aid in?


    I have a piece that has a 1 cm diameter, press-fit into a stainless steel fitting. Looking through it I can see it is a bit hazy. Want to polish it or something. Need to be able to look through it and see a perfectly clear image.
    Anyone have tips to "clean" it.


    PS. No harsh chemicals, nothing heavily abrasive, nothing that will leave a residue is allowed. (needs to be in a super clean environment)

    Any advice!! Please! :help:

    You can only polish it with an abrasive and labour.

    Don't mind the elbow-grease. Recommendations on a good abrasive?

    If not for aquarium use, try spirit vinegar. Clean my tanks on the outside with it.

    this has been discussed on this forum before.. cerium oxide & a buffer apparently works if the marks or scratches are not too deep

    Didn't know, my apologies! :notworthy:

    Will give it a google, thanks!


    Luckily I have a Dremel at work. Should help with some of the elbow grease...
    Will give a few things a try (and post pics if anyone is interested? )

    Sounds strange, but I use Brasso to polish minor scratches in my underwater camera housings and lenses ... ?!
    Have also used toothpaste first (more abrasive) followed by Brasso (finisher)

    Re: Re: Polishing Glass

    Thats very usefull, I've been meaning to ask about a "scratch remover" for a while! So this cerium oxide/ buffer are they widely available products? Is it non toxic? And WHERE CAN I GET IT!?

    Thanks.

    I have used Brasso on perspex dome ports on underwater housings with success, but not on glass yet..

    cerium oxide is available locally, just can't remember where at the moment, try the hardware store for starters :scratch:

    My boss bought the Dremel polishing kit.
    Starting using it this morning. It's working ok, but still a way to go.

    I have given this some thought and I do have some cerium oxide, but i dont think it is the way to go unless you have many many hours to polish your glass,
    I know glass melts at about 1400 degrees give or take, so im thinking of just getting a blow torch (will do a test before i use it on my tank) and blow torch it
    for a few seconds then use a iron on it to smooth it out.

    BTW you can melt glass in a microwave, you have to get the glass started melting first by using a blow torch, then throw it in and the glass will continue to melt,
    thought id just add that if anyone needs to make weird melted glass decor...

    Hahaha!

    Getting it to cool down without cracking is going to be very hard

    Hahaha!!

    I can just imagine some Charlie grabbing a blow torch from his garage and aiming it at his tank. ;D
    I'll see if I can take a couple pics tomorrow. It'll have to be from the phone cam, but the before and after it pretty obvious so it should show nicely.
