Since I took down my 40gal sump, I have a couple pieces of glass that are the same size and want to try making a small tank out of it but every piece has a lot of silicone on it. I'll razor blade off most of it, but want to get it pretty much clean so the new silicone will hold. Is acetone fine to use to remove it?

Acetone is a solvent and will not hurt your glass in any way

So after I remove the silicone with it, how should I clean the glass in to get rid of the acetone?

It will basically evaporate on its own quickly, but you can rinse with hot water if that gives you more peace of mind. Fingernail polish remover is a diluted acetone mixture. For as potent as it smells, it has a very low toxicity level

On a side note, not sure what size of tank you want to build, but there is "glass glue" that is way stronger than silicone. Loctite makes good glass glue. Water resistant, not waterproof. Glue for bonding and silicone for sealing. Make sure your silicone is aquarium safe, meaning no mold inhibitors... poison to fish.

It's gonna be a really small tank, probably 10 gallons or less. For this small of a tank, silicone would be fine right? I'll go measure it out really quick too. So it'll probably be cheaper to get nail polish remover then?

The glass is quarter inch thick too lol. Some thick glass for a small tank!

That small, yeah you're good with silicone as a bonding agent, and really I think if you scraped the old off with a blade, you really dont need a cleaner. Not up on nail polish remover prices, but acetone is not expensive.

Well I might have some remover around the house somewhere, so I'll look for it. The tank is gonna be about 5 gallons I think. Probably use it as a betta tank or something like that OR a small aquascape with shrimp maybe :)
