OK...Point well taken. However, when the plugs are old to begin with, it is almost impossible to get them pliable even with Lacquer Thinner. DAMHIK...cr8crshr/BillUsing lacquer thinner on cleaning rubber parts has worked for me for years. So saying lacquer thinner will eat at the plasticizes will promote faster dry rot and hardening, I'm not going to argue that.
My plugs are fine, all I hear is blah blah blah.
WD40 works good too, but it draws dust/dirt to them so there's my blah blah blah lol.
Happy 4th of July weekend to all.
