Silicone Residue Removal

[Stef]

Apologies if this has been answered in the past.  I have a used 3.7 gal Imagitarium kit tank that's been in storage that I removed the internal filter compartments. The compartments came out ok, but left stripes of silicone residue.  I've been razor blading it off, but there's still stripes of residue.  The more I razor blade it, the more it just gets streaky and kind of greasy-like.  Maybe it won't show up when it's filled and scaped, but I was wondering if there's some safe product to remove it.  Would this be white vinegar?  Didn't want to use Goo Gone or something harsh like that.  If vinegar is the ticket, could white or red wine vinegar (for cooking) be a solution?  I don't have any normal vinegar for cleaning.

If you have white (or any vinegar) give it a go.

Is it a glass or acrylic tank?

I've used nail varnish remover to clear sticky residues on surfaces but friction is probably the best for silicone if not the fastest.

It's a glass tank and the silicone streaks are on the inside of the back and side panels of glass. The original silicone was black, so the streaky/greasy residue is kind of grey ish

I have used this OLFA Square Razor blade several times for resealing tanks. It in my opinion is the best for silicone removal without digging into the corner/seal. When the blade is brand new it is also excellent at removal of residue, it comes off in thin sheets. 

I think its exclusive to Lowes.

The vinegar and elbow grease worked.  I ended up using a rough terry cloth towel and buffed off the vinegar.  Rinsed the tank afterward in super hot tap water. I think my razor blade was dull which only made it worse.  Thanks @Flumpweesel and @StevesFishTanks!!
