If glass use a razor blade. If acrylic...... well....... I guess you have to drain the tank and wash it with vinegar or muratic acid...?

razor blades. (carefully) the Kent scraper is awesome too. But for hard to reach places nothing beats a razor on its own

A credit card on acrylic works just fine... I did it last week. I washed the card first...

... and then flogged myself for letting it get so bad...

Be sure to wash it off first! They have some coating like oil or something on them when new. I just run it under hot water for a bit.
