It’s a little dirty, and I’ve tried cleaning it with iso and salt but some stains remain. There’s no cracks, other than the mild resin inside of it which can be cleaned, it’s a great ash catcher. I’m retiring from my smoking days and would love for someone else to enjoy and use it. I also have a bowl that comes with this catcher as a set, if you wanna buy that it’s on my page!
