Help! Will lubricant affect spkr.cables?


My H.Tech. Pro-9 bi-wire speaker cables are a very tight fit when trying to slide them up inside my B&W speaker stands. If I put some lubricant on the outside cover to help slide them through would it affect the sound of the wires? Any recommendations? I don't want to damage the casing in case of future resale.

I will look into the French chalk vs. talc, and check with the manufacturers first. Good suggestions! Thanks. Any more?
Sorry all, I feel like a moron. I posted about this way too late at night and thought you were having a tight connection with the ENDS of the cables (Tight terminaters). Please ignore my comment.
Why not just use a snake to pull wires through? As far as lube, soapy water since it’s the mildest thing I can think of
