My Chlorine Only cylinder is stained with many black spots from using the DPD powder. I have tried washing the cylinder with very minimal results. It is getting to the point that I can barely see the markings of the cylinder.
Why is this happening and what can I do short of buying a new one (I just bought one at the end of last year )? Thanks!
