I flush blocks, rope clutches, etc liberally with water. The only lube I would be tempted to use on Harken blocks is McLube.
I use Superlube on slides and T-track things. Don't forget to flush your furler drum and swivel with water at LEAST annually. T-9 is for electrical use, not lube applications. If you want to spray a corrosion inhibitor on blocks, try Corrosion Block. It doesn't last long but it doesn't seem to leave a residue. Dennis C.
