Myersc1989 Posted March 30, 2022 Share Posted March 30, 2022 Hi first post here. I just bought a used 20 gal high. I tested it for leaks but had none. When I got in the tank to clean it up I noticed that the seams were pretty shot looking. I decided to just go ahead and reseal it. I'm currently scrapping the seal from the inside and come across an issue. Everything I've read or seen says to scrape then remove any residue. I'm using 99% isopropyl alcohol or vinegar. I can't seem to remove all the residue from glass visually. When I touch the spot it feels clean. So the question is can I go ahead and reseal it or do I need to get it off. Picture is off the worst of it. Link to comment Share on other sites More sharing options...
