I had seen this on Shark Tank recently and, as usual, I had my pipe goggles on. If you're not familiar with this product, it's a cleaning sponge that is either soft (in warm water) or hard (in cold water). What caught my attention was the claim that it would not scratch any surface. Naturally, the thought of estate stem cleaning applications crossed my mind so I'm trying it out today. I spend a lot of time on stems, including going through all the micromesh pads for a mirror-like shine, but it really takes effort to get them that way. If there's a short cut to be had that gets me there sooner- hook me up!
I chose this pipe from my backlog of estate pipes, an Amphora Extra 509. The stem isn't in too bad shape, and I won't be terribly heartbroken if I screw it up.
This is a work in progress, but here is the stem just after I soaked it in Oxyclean for an hour...
...and here it is after just a couple of minutes with the Scrub Daddy using cold water so it had a harder surface. These are iPhone pics so hopefully you can see the difference. I'm noticing a shine already, this is promising.
I'm going to let the stem dry out for a bit to see how much oxidation reappears, and report back later.
