I have no idea what is going on here, I have a Czech pipe tamper that I have used for two years, so I really am getting attatched to it, even though it is a cheap $2 tamper; it has always looked quite stunning. Anyway, now it has developed what looks like a white film or discoloration (not sure) near the bottom of the tamper area, I am not sure what this is, nor can spit, water, or even a standard cleaner remove it like soap or a laundry/carpet stain remover. Anyone had this happen to them, know what it is or what to do with it?
