I had to remove the faucet today and put back on. When I did the cold
water side comes out very slow. We have very hard water and this has
happened before, but there was a plumber here that time.

I can not remember how exactly he cleared it. But I remember him
turning off the water at the water heater then he opened a faucet in
the bathroom and either blocked off the one in the bathroom or kitchen
and put back pressure on the line and it cleared.

Does anyone know the correct procedure for this?

Disassemble the cold water side valve on the faucet.
Slightly open the valve under the sink to flush out
the line.
