i built two 41 qt. racks for 12 adult female ball pythons that im picking up soon. the racks are made from particle board treated with a marine grade varnish. i was recommended this technique from the owners of a reptile store where i shop. its been about a month since i built them and i can still smell varnish in the tubs. there is no snakes in the rack yet for this reason but im convinced the smell is not going to get any better anytime soon. do you think this is safe for me to make my purchase and put the animals in.....any ideas on getting rid of the smell?...thanks
