Removing silicone before making tank- how clean!
 

Im turning my 125 into a sump for my new 180, so removed 4 x 1/4 inch thick glass baffles from a diy 40b sump. I’m thinking I might use the glass panels to make a small 7.5 gallon mangrove tank to pretty up the basement sump fishroom. Cute little 17w x 8d x12h.

I’ve been scraping silicone off these things whenever I get 30 minutes free for 2 days . I’m down to a really thin film, not continuous, and was wondering if i should keep trying to get it all completely clean before attempting to make the tank?

Magic eraser and more elbow grease? Any tips?

Cheers

All of the above...razor blade...vinegar soak...magic eraser..whatever works

New silicone will not adhere to old silicone, so therefore it must be completely removed.
Google remove or dissolve silicone, there are lots of products that will help remove any residue. Some can even be had at Lowe's or Home Depot.

Acetone

Made some progress with spraying the edges with wd40, wrapping it in seran wrap and letting it marinate for 4 hours. First panel took 10 minutes to scrub off with a green pad. That pane looks good as new.

Acetone and steel wool works like a charm.

Yep, acetone & steel wool works well to get the final haze of silicone off.
