Muriatic acid find it in pool chemicals and use good gloves. Rinse thoroughly afterwards. It dissolves it quick and will almost wipe off if it glass. Dont use on acrylic.

Use CLR cleaner, wear gloves it will come right out and wash the tank out after.

Watch out for the Muratic Acid as it fumes quite a bit. If the glass is etched, they won't come unless ground and polished out and if attempted it's a lot of work and can't be done at all if the glass is tempered.
