getting silicone "stain" off glass?

[number6]

I have a used tank and a

background was once used in the tank itself.
The silicone they used has left a mark on the

glass. Is there an easy way to get it off completely? It won't scrub off and before I see if a

razor blade can do a better job (and I avoiding scratching the glass!) I wanted to see if

anyone knew of a trick or two...

Acetone is the solvent used in silicone

sealant. You can use it to remove the last little bits, but a razor blade is best for removing most

of the sealant. Acetone is a known carcinogen, so I recommend using it with rubber gloves in a well

vetilated area.

I have not seen spec

sheets for aquarium silicone so perhaps the solvent is acetone.

My nose tells me it is

acetic acid.

cool. I'll try the

acetone 1st. I'm going to tip the tank on it's side, and use plain non-clumping cat litter

to coral the work area. This way I make sure no drip or anything hits seams.

Thanks

guys! http://cichlid.ipbhost.com/style_emoticons/<#EMO_DIR#>/smile.gif

You're right, I'm wrong, it is acetic acid that is

the silicone solvent (must have been sniffing too much of the stuff). Try white distilled vinegar.

If you need something stronger check photo stores of acetic acid where it's used as a

"stop" in printing photos in a darkroom.

ah, thanks Mike... I went

looking for acetone last night and didn't find it.

Vinegar shouldn't work

should it? makes me worry about all the times I've used straight vinegar to clean a tank of

hard water deposits... http://cichlid.ipbhost.com/style_emoticons/<#EMO_DIR#>/blink.gif

you can find acetone in the health and beauty aisle at walmart. its a nail polish

remover.
also in the hardware store in the solvents aisle.

can you believe that the hardware store

didn't know they had any then? They also told me to head to Wallymart for nail polish

remover... maybe it's just cheaper.

Anyhow, will try vinegar 1st followed by

acetone to see if these work.

Then on to the cedar racking... http://cichlid.ipbhost.com/style_emoticons/<#EMO_DIR#>/biggrin.gif
