I once had a Kenyon alcohol stove. Nothing but problems and one serious
fire.. Ya can't see the flames.

If I remember correctly, the 'cleaning' is a function where the needle valve
is use to purge any gummy buildup in the needle valve passage. I don't
remember how it worked.

My recommendation is to ditch the Princess and get a non pressurized
stove.. If you want alcohol stove, use one of those sterno types with the
refillable canisters.
