Hey all, I was wondering if anyone has any tips or tricks to remove silicone residue? I've tried rubbing alcohol, sos pads, goo gone silicone caulk remover and countless hours with many, many , many razor blades and just no luck.

Fresh razor blades to remove the bulk of it and magic eraser for the rest.

The angle of the razor blade makes a huge difference too.

Methyl hydrate and 0000 steel wool.

Well no luck with the magic eraser or the acetone. I've resealed many aquariums before, but never had so much trouble getting the residue off as this one.

Well I guess I'll pick some of this up tomorrow if I have time. Hopefully it works. I'm tired of looking at this tank empty.

wd/40 should soften it up, wait 5 minutes and then you can just wipe it off with a rag

I wouldn't use WD40 - too much stuff in it

99% Isopropanol (isopropyl alcohol) works well on the leftover film
Drug store stuff

I used the replaceable blades for an olga knife. Very sharp! Just cuts the silicone off. 2-3 blades is all you will need. Then I used alcohol to clean the glass before putting on new silicone.

Stainless steel razor blades are the best, they don't scratch glass. (as easy)

I spoke yesterday with the GE sealant people and asked them if they make any silicone that is aquarium safe. Their answer NO, all their stuff contains mold and mildew chemicals. So GE I or GE II that some of us used over the years is now included in the formula. :neutral:

Whoever you spoke with must not know about GE SCS1200.

Most of the aquarium builders use it.

Isn't that what you use to make oil?

I'm not trying to start anything, just passing along what I was told by GE and read in their information . :wink:
Aquarium builders should read these Data Sheets, unless I missed it I could not find anywhere where it states that GE-SCS 1200 is aquarium safe. The last point on page .02 under not recommended is a good clue that it shouldn't be used in continuous contact with or under water.

Interesting.

From what I am reading it says "Contact Momentive technical services for applications where sealant is used underwater or in continuous contact with water."

The other widely used silicone for aquarium building is the Momentive RTV-100.

I don't build aquariums but have always used NuFlex 333 Aquarium silicone for resealing jobs and repairs. Recommended by my local glass shop. Think I paid like $10 a tube for it.
