Gdetrailer, The only plastics wd40 says to avoid are polycarbonate and polystyrene ( mostly clear ). Don't think this includes sewer hoses.
In my case the tube dries before the hoses are inserted. I do not spray the hoses.
Been spraying my outboard motor, small engines, and all kinds of things that have plasic on them for years. Never had a problem with plastic melting away so not to worried.
I am more concerned about my sewer hose failing due to poor construction and crappy materials used in making it. Tossed the el cheapo that came with the TT and now feel pretty confident it won't blow, especially not spontaneously. :)
Search WD-40 MSDS, you will find that it contains PETROLEUM BASES.
Many plastics also use PETROLEUM BASES.
While it may appear to not harm the plastic at first, it WILL over time degrade most plastics that have come into contact with it.
When WD-40 "dries" it leaves trace amounts of light oil.
You push and pull the slinky in and out and the coil spring edges will be in contact with that trace amount of light oil.
I have seen different plastics react to oils like Diesel, motor oil and even spray oils, not to mention gasoline. Some get soft, some just melt and some get brittle..
Don't believe me? Search for PVC/CPVC oil resistance, plenty of PVC/CPVC manufacturers warn of direct contact with other Petroleum products and I even found one manufacturer that DIRECTLY MENTIONED WD-40 as one to avoid contact with.
It is your life and your problem if that slinky fails while dumping, as for me, no thanks.
