What product do most use to clean and protect hose and electrical conduit lines.
I've been waiting to see if anyone would take a crack at this....
My short answer is I don't use anything on the hoses or wiring to preserve them.
I take that position, because I don't want to mask any leaks, or add to trapping dirt or moisture around electrics. Plus, I'm just not that into doing detail work. I'd rather ride. My diamond in the rough, so to speak.
Armor all, hose spray you'd buy at the auto parts store...... If it were used with care is probably not going to cause issues. Far better to apply it to a rag and wipe that on the part you want to preserve, than spraying goop into cracks and places you can't get it out of.
When stuff like that drips away, it will look like oil, or coolant..... Not to mention how slick most of these products are. I will never, ever use any sort of tire dressing. Too slick. Too risky.
I have experimented with various petrochemicals, to see if I can preserve the appearance of the plastics which are only cosmetic. Switch covers, mirror backs, rear fender...... Few things maintain the deep dark wet look the new parts have, as the aging process goes on.
So far, air filter oil, and left over fork oil seem to be as good or better than wax, or any version of armor all I have tried. Only improves the appearance for a day or two, before fading back to the weathered appearance it has otherwise.
10 year old cosmetic plastics can realistically only appear new, by replacing with actual new parts.
This is because the surfaces are evaporating. The smaller molecules in the mix, leave. Outgas. Can't be stopped. (Think of how much plastic things stink of chemicals when you first unwrap them)
As the surfaces become less smooth, they appear dull because they don't reflect as much light. The mirror finish alters. Almost all plastic parts are cast with textured surfaces to mask imperfections, and to soften the impact of the aging process.
My advice? Ride. Fuggedaboutit.
