Advertisement Hey there Recently I bought an old Exo Terra-Terrarium off someone I found in one of these craigslist-like apps. It´s nice and big (45x45x60 aka 18x18x24 inch) and didn´t cost much (20€-thats nearly free for this size). Sadly there is a problem with it (as with most very cheap things): it spend the last five years in the flat of chainsmokers and it strongly smells like nicotine. I had the whole thing soaking in my bathtub for about 10 hours and after a lot of water changes, it seemed kinda clean and the water wasn´t brown anymore. It still has a lot of the smell on it tho. I don´t want to risk that the animals I´m going to put in there will get any health issues from this, so i would like to clean it even more. My dad recommended bare soap and vinegar, but I´m not fully sure if thats the best thing to do. Does anyone here have a clue how to get rid of the smell and possible nicotine-residues? Any advice or ideas would be apprichiated.
