I have a counter-top gas stove - one valve is difficult to operate- requires more force than others?

Question

Is it proper to lubricate this valve with WD-40 or should it be left as is or disassembled and cleaned? Keep in mind that the valve is probably 45 years old. Other wise the stove works just fine.

Answer 1

The valve needs proper lubrication, go ahead and use a straw on the WD-40 and shoot some in the stem area.  Work it a little bid and that should free the stiffness.

Answer 2

My company used "stop c**k grease" in older stoves.  I wouldn't use the wd-40 on it.  It might start leaking.
