Fixing my vanity faucet

repairing the faucet on my vanity In addition to having less water pressure, my faucet's cap was rusted and extremely tight when I attempted to open it. After a minute of waiting and spraying WD-40, all the rust disappeared. I then opened my faucet cap and cleaned it, but a lot of dust particles were in the water. I then sprayed WD-40 again, replaced the faucet cap, and the water pressure rose. I'm grateful to WD-40 for creating such a fantastic spray to get rid of rust from items I can't open.
