All my floats and trowels are coated with cement and rust,
but now i want to do some smooth top coats of plaster.

After scraping off the cement with a chisel and wirebrush
what should I do?

After using them I used to rinse them then leave them to dry.
Is there a better way of doing it?

Should I segregate top coat plaster tools away from any cementy work?
