I put a scoop in about 12 ounces of water and stirred it up. On a later batch, I used one scoop in about a liter of water in a long pan for a churchwarden stem (it cleaned up fine). Should I go to something coarser than the 800 sandpaper for the initial sanding?
Here's a before picture of the bent bulldog (second from the left).

Hi @Haebar,
If you have collectible pipes you’ll have to be more cautious in what you can do. Sometimes it’s better to leave something alone rather than to make it apparent that it was worked on. Refrain from buffing but if you do, cover the nomenclature with a mask (lke masking tape). You will read many places about using tripoli or other compounds (rottenstone, pumice, rouge, white diamond, etc.). Some of these are used on pipes BEFORE they’re stamped and finished but they’re not intended to be used afterwards. eBay is filled with pipes whose value was compromised by inappropriate buffing.
A light buff with carnauba is ok, but only to polish the restore but afterwards you should hand polish (not too hard) because even this can affect nomenclature. The crisper the lines and nomenclature the more value that you retain.
I just sold some Charatan pipes on eBay (pcs of one below) that I restored. Rather than do anything to the Cp stem logo (you had a question about this), I masked it and used micro-mesh pads (close) around it because any abrasive would have eliminated it.

You can barely see the Cp but that's how I received it. I used Dollar Tree brushes to clean the sandblast and rim.

The pipe was received so heavily caked that it's functional diameter was a like a 40 ring cigar and it had a lot of rim build-up. In this photo you can see the ghost of the stem oxidation near the saddle. It just wouldn't come off. The button was pretty well damaged as well with some moderate indents top and bottom but the smoke hole was in good shape.
I'm a little hesitant to describe this method so I'll start with a warning. If you use this method (below) use care because you can damage the stem easily and I have.
Fingernail files are sold that have many grits including ones that have several increasingly fine grits (a system) to buff nails. They're hard backed (usually with a stiff foam) and are very good for re-working stems but their finest grit is nowhere near polishing quality so you'll have to finish with micro-mesh or the papers I listed in my previous post. The fingernail files (foam backed - not metal or regular wood files) are rigid enough to allow you to keep the intrinsic lines of the stem. From your posts I suspect that this was a problem for you (too flexible).
Yes, these files can be as coarse as 150 grit (heed my warning) but I usually start about 240 to prevent creating lines that subsequent grits can't remove. If I were you I'd start at 400 and try it on a test stem until you're comfortable. The benefit of this method is that you are removing oxidized material rather than cleaning it, so it's more permanent and as you become adept you can reshape the stem as needed. I never shape stem barrel (as it approaches the shank) other than to get off the oxidation. Changing the barrel shape is a hornet's nest (yes, I've done that too).
ALWAYS work in the same direction, ALWAYS! Even if you feel that you're not getting any purchase, resist the urge to sand parallel. Always work with the most care near the mortise joint and at the button so that you don't remove too much material. A couple of heavy swipes and you have no button.
The coarser grits can take off a lot of material so go slowly. Do all sanding with one grit at the same time - stem, button and smoke hole. Then proceed to the next grit. Keep in mind my previous comments about not going even as far as flush with deep teeth indentations. Do what you can but no more.
I buy these files at Harmon's and for you better looking (than I), unattached guys you can meet some ladies this way but I only get funny looks while I fuss through the files available.
Hope this helps.
Pete
