I mention items not as an expert but rather just things that worked for me. As a drag boat racer any
oil or?? was spread around by water in the hull coating everything.
First off, wear leather gloves so any stray whiskers on the hose will not cut you as you clean and handle the hose. I would spray with carb cleaner to brake down any
oil in the weave. Carb cleaner does not evaporate as quickly as brake clean but it will leave a residue. Scrub first with rag and carb cleaner and repeat with brake clean to remove anything left.
A blue and red Sharpie works well to touch up any wrench scars on the fittings as a final detail.
