WD-40 or Gulf Wax for use on Plumbing....?
If I use W-D 40 spray on a plumbing fixture to loosen up the action on a pull-out shower valve, could the oil have an adverse reaction with any of the plumbing glues or putties used in the valve? Would it be safer to try parafin wax instead?
Wax would surly bind and the WD-40 stuff will only grease thing up.
I use it to lubricate and seal o-rings on cartridge valve rebuilds
