I have a leaky kitchen faucet. I am trying to fix it but the screw at the top knob, will not move. It is a phillips screw, but seems to be froze up form old age. How do I get this loosened, I tried PB blaster, but not working. What do you recommend? Thanks

Suzy, spray WD40 on the screw. Be generous. Let it set over night. Next day, take large phillips screw driver. Put it inside the screw slot STRAIGHT on. It cannot be under angle. Push as hard as you can while turning. Once you break the grip, it will go all the way...

Let us know how you did...
