I got a used 60g cube today. Great price, but the acrylic is really hazy. I have not started to clean it, but I think that it will still have a foggy look to it afterwards. Should I wet sand it? I'm scared it will leave swirl marks. Can I use a liquid buffing compound like they sell for headlight restoration? If so, is there one that we know is safe with aquariums. I don't want anything that would be toxic to saltwater fish if some was still in there
Any feedback is greatly appreciated!
