View Full Version : cleaning silicone from glass
Got a leaky 33g Hagen. If I can seal it, thinking about using it for a ref and trying different overflow techniques.
I've removed all visible silicone from inside but wondering what to use as a solvent to ensure I can get a good bead of caulk down?

try goo gone, if you don't have that, canadian tire or similar places should have silicone dissolving stuff.

I don't know about solvent in the tank but a razorblade gets most of the old silicone off :biggrin:
Got the silicone off with a Olfa blades but seems like there's a greasy residue left.
Use a vinegar and water mix. That should help remove the gunk.
If you don't want to use a solvent (and I don't think you do), then try some low heat and/or a bit of friction (a chamois and some elbow grease has worked for me). If you use a hair dryer or such, be very careful not to get it too hot. If you overheat the glass it can crack when cooling.

I've done that in combination with a new razor blade and it works nicely.

Straight Vinegar, kinda works or at least works in a pinch.
Or Acetic Acid, Glacial.

Vinegar will not work to get the greasy layer off a large amount of glass. Been there, tried that.

Vinegar and water with razor blades and a towl combined with some elbow grease has always worked for me

i use 100% alchahol, or as close to 100% as i can get at the grocery store. i think it is more like 99%. it works great and it evaporates so fast and does not leave any residure. i clean it off anyways with water. or you can use methylhighdrate (probably not the correct spelling). i know that this is actually the best food safe product to use but i don't know where you would find it. hope this helps.
