After completing my 400 build I noticed a residue on the glass. Im not sure what its from but I dont remember seeing it when I started. Maybe I didnt look close enough, b/c the glass was used from an old tank. I have been trying to clean it for a while now but I can't seem to get it clean. What can I use to clear the glass up. I've tried scraping it with razor blades, using apple cider vinegar, stronger industrial cleaners, but nothing has worked. Is there a way I can buff it out?
Any advice? Thanks
