I used purple power to clean the gunk off of mine and see if they were supple enough to re-use. plus I did re cover using harness tape to keep things looking new"ish" plus it removed most of the oxidation which surprised me.Before I decide to purchase a new wiring harness I thought I would check the one ithat was in the car and an extra one I have. Anything I should know. Best way to clean ECT.
Well, knowing what I know about wire harnesses, I personally would never submerge my cars wiring harness in any liquid. Except maybe isopropyl alcohol, that has a tendency to flash off fast. Wire tends to act like a big sponge and will suck up the liquid and hold it for a long time (wicking). Most wire harnesses produced in industry are tested (insulation resistance, dielectric withstanding voltage) for that and other non-conformances before being put into service. Separating the wires and wiping the outside of the insulation with alcohol and a rag is the way to go. JMO.
Do not be fooled, find a piece you do not mind splicing and strip it back. You might be surprised. California and Arizona cars and areas with low humidity might be fine but for most of the rest of us it is suspect.
My sister in-law works for an insurance firm and happens to tell me different. It AIN'T the wiring that causes the cars to get totaled, it's the hidden areas that never gets cleaned and the water/ corrosion get into everywhere ,seats and carpet trap water and mold, electronics get ruined and all the Seals in the windows,doors headlight,tailight and trunk area trap the moisture causing problem later on in the cars life , it's all about cost. if they had to replace everything that traps moisture they would be out even more that the (any) car was worth. if it was just about wiring they could have easily replaced the wiring and been done with it. fact in point during the 09 Atlanta flood a friend of mine had a 2000 F-150 that had some water damage, water went up to the rockers and never got any higher than that (flood damage in his garage walls showed the high water mark so we knew how high the water had risen) they totaled the truck not because of wiring or anything else but just because water had hit the rockers and gotten the carpet wet. cheaper to let him get a new truck than fix the rocker problems he would have had.Might as well drive the car off in a river. This is exactly why insurance companies total cars that have been submerged.
Vacuum pot to remove air (I use that one to do my Resin casting and the odd cleaning procedure) like this but not this one a 5 gallon onePressure pot?
