WD is a very good product with many uses. Use it to clean chrome, leaves a light film that evaporates when running temps are reached. Cleans SS braided fluid lines, pictured, like no other product I know of. S Green and WD are the only cleaners I typically use.
Hold a rag under the line, spray along top, crap runs right into the rag & wipe, so easy I could fall down.
