Fixing my Vanity Faucet

Fixing my vanity faucet
My faucet was giving less water pressure and when i tried to open the cap of the faucet, it was rusted and very tight, not opened.
Then I spray WD-40 and wait for 1 minute, all the rust came down and then I opened my faucet cap, cleaned it, there was a lot of dust particles came with the water, and sprayed WD-40 one more time , then i put back the faucet cap and the water pressure increased.
Thanks to WD-40 for making a very awesome spray to remove rust from the things that I can't open.
