While this doesn’t directly address the original question (something of a tradition on
Internet forums), I added a second shore-power inlet in my
anchor well, so that when docked bow-in (my usual), I don’t need to run a second 50’ cord the length of the 45’
deck to get to the cord that reaches the
pedestal.
On the original topic: I do have one cord whose plasticizers have leached creating a sticky sheath that collects and holds dirt; that one has been demoted to my “on the hard” cord. I’ve found the only way to get rid of the sticky is to let it attract and hold enough dirt/dust to provide a (not pretty) non-sticky surface.
Tried
cleaning it off with various products, but based on how long the first 12” took to clean (and it remained sticky), I may not live long enough to do the whole thing.
I suspect (just a theory) that treating a brand-new cord with something like 3M 303 Protectant might prevent or delay the original plasticizer problem. Not sure about mildew though.
