Cleaning wires

I have reused several harnesses. I take em outside and spray them with Spray 9, scrub em with a small brush, hose em off. Let them dry fully in the sun. Then I spray them with WD40. They usually look brand new. Mind you, these are harnesses with soft , supple coverings and I do check for green and black oxidation before I use em. I like to use the originals if I can.....
