It is brass and I've tried to apply penetrating oil a couple of times now and still cannot get this thing to budge. Any suggestions on how to safely remove this unit without breaking it? | | | | | Joined: Feb 2004 Posts: 29,799 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,799 | A little heat from a Propane torch, followed by tapping the wrench flats with a hammer and a blunt punch will usually get things moving. PB Blaster is a good penetrant- - - -KROIL is much better. Heat- - -tap- - - -soak- - - -repeat.
