Sure...
I start by reaming with a PipNet set then move on to an oyster shucker to scrape out some of the cake.
I clean the outside of the stummel with Murphy's Oil Soap (I plug the bowl with a cotton ball) rinse really well with warm/hot water.
Soak the stems in warm/hot water and Oxiclean, remove crud with a magic eraser, then polish with micromesh pads. Coat with mineral oil and let them sit and absorb. Apply a coat of before and after restoration balm, let that sit for a while, finish with Paragon Wax.
The stummels get a light polish with the micromesh pads if needed, a good coat of before and after restoration balm, finish with Paragon or Halcyon Wax.
Internals are cleaned with Everclear, q-tips, bristle pipe cleaners, an ear wax removal set of tools (kinda gross but it really allows you to get the tars out of the shank)
Any pipe with bead lines get a gentle cleaning with a set of dental tools, to get all the crud out of the valleys. They are also great for getting tough residue out of the end of the stems, where they flair.
In the case of stubborn ghosts I use cotton a ball and Everclear soak and or a warm damp coffee grind treatment to pull out the funk.
Stems with bites get painted with a flame first to raise the indents, filled with black superglue if needed, then worked on gently with needle files and sanding pads. I do not like to remove material if at all possible.
To recolor the logos on the stems I stole an idea Ken Barnes mentioned in a thread about Upshall pipes ... white
ons!
