Silicone removal

[MattW]

Just spent the last couple of hours scraping off as much silicone as possible on my dismantled used tank. There is still some residue on the glass that I can't get off with my razor.
Is there a product/method that would help at all to remove this?

I've read that either vinegar, alcohol, or WD-40 helps. I've already used 70% alcohol wipes but not much happened. I'm guessing 90%+ is needed?

Also, would a good soak in warm and soapy water help? I read it could help but was unsure.

Though whether they'd contaminate the glass I'm not sure.

I don’t think you need to worry that much . I would wash it well and take some isopropyl alcohol to it and then go to work resealing . I’m going to be resealing an aquarium this week and that’s all I plan to do .

I've been looking at bar keepers friend as well. The tank I bought has a few scratches and was outside, so it's a bit weathered too.

I used barkeepers friend for resetting up my tank and it all washed off no problems. Not sure how well it works on removing stubborn silicone but it got rid of everything else just fine.

The glass wont "soak" anything. commercial foam caulk remover can be used at large.

I use rubbing alcohol, isopropyl or ethanol, to remove silicone traces. You may have to do it a couple times. New silicone will NOT stick to old & you won't get a tight seal. Try not to let it get between the glass joins, those are structural. Don't forget the under the top rim framing. Less important I think, you shouldn't fill the tank that high but you still want it to hold.

Is this your tank w/ broken end glass? (is that you?) Then you need to gently shove/wiggle a razor blade w/alcohol between the joins (but only on that end!). I've always chickened out of replacing broken panes, be very careful!! You might put the tank on its broken end & allow the alcohol to soak in & soften things up. But brace the tank so it can't tip over easily especially if you have kids or nosy pets.

I don't know if you have glass repair shops near you, but they might be helpful. I got a rimless DIY tank that didn't have a way of holding up lights. They seemed happy for a new challenge & we drew diagrams of what I wanted & size specs (no charges yet). They even rounded the edges so I'd be safer! It cost (back then) under $10 USD. It doesn't cost anything to ask & they might be very helpful. If you have a fish club, there may be someone there that can help w/info too.
