How Often Do You "Deep" Clean Your Pipes?

[Pipe Smoker]

I don't ever deep-clean pipes. I smoke only one pipe on any given day. At the end of the day I spend close to an hour cleaning that pipe. I clean the rim with Everclear (140 proof), then EVOO. And swab out the bit and shank with pipecleaners wetted with Everclear.

If the pipe has a vulcanite bit I polish it with Colgate toothpaste applied to a tensioned piece of flat shoelace. Then a final polish of the bit with neutral Kiwi shoe polish.

Not regularly, but as needed, I ream. And clean the outside of the pipe with EVOO.

Edit: My cleaning procedure for my metal-stem Kirsten is significantly different…
