Compressed air first…if your mold is properly waxed and buffed 90% or more of the PVA will leave with the part as it’s pulled and usually the remainder of it can be blown off the mold surface with compressed air. It’s been a long time since I’ve had to use water to clean a mold surface of PVA, when I use PVA that is.
