Help! I can't get these spots off my glass!

    I'm trying to clean the glass before setting up a turtle tank and I can't get these spots off.


    I have tried

    a razor

    all of which with lots of elbow grease

    nothing works. I have no idea what they are but they seem to be embedded in to the glass if a razor can't get at them..

    Alcohol and vinegar is a big no no for tanks. Are these spots on the outside of the tank or inside?

    Have you used water and paper towels?

    What kind of vinegar did you use?
    If the spots are calcium deposits then white vinegar or apple cider vinegar ime works best

    glass tank right? Swirls? did this used to be a saltwater tank? If so, you may not be able to get them out, they could be etched in the glass.
