this might be a stupid question, and i'm an amateur.
I dont have a wash-out booth but there is something similar to one in my apartment complex's laundry room. Where the washer water is drained. would it be hazardous at all of I used it as a wash-out booth? Would the the chemicals coming off the screen cause any problems?
If you use proper Industry reclaiming chemicals you should be fine as most these days are drain safe. The apartment people might not like you doing this in their sink though. Might need to get permission before you jusmp right in.
Are you talking about one of those plastic tubs that are on 4 legs? You can also buy those at Lowe's, Home Depot etc. They are pretty inexpensive, and I think you can just hook up a garden hose for the drain.
