Need extractor for moen diverter valve installed for tub/shower application. Valves include hot water -- diverter valve -- cold water aligned left to right. Diverter handle will not turn and can not remove valve even after several days of soaking with vinegar. Moen part number for the valve is 94543. Unable to locate puller for diverter valve.

Use CLR product. It can be purchased in any large supermarket. Put it in spray bottle and generously spray the assembly. Let sit for 1/2 hour. It will help.
