Very smallest spot I couldn’t get clean (not the right equipment) but has been cleaned and has great heavy function airflow it’s name was pancake because of the base 
It’s base is part of function 

All you need to clean it is iso and salt. No equipment needed. Also, use something to take those fugly stickers off the side. Its not a recycler, its used, and it was shipped in from china. Fucking thing is worth a box of rocks. Maybe less depending if the rocks are in nice shape 🤣

@grizz I used iso and salt it’s it a hard spot and was soaking for 3-4days and still cant get the spot ,it wasn’t shipped anywhere I bought it in person and the sticker just matched at the time I like how u spent the time to be rude asf for no reason must mean you have no life hmm 😝
