Removing melted vinyl from exhaust pipes


 

Have a problem which I hope this forum can help me with. I recently took my daughter for a ride on my Harley Davidson. She was wearing a jogging suit and when she went to get off, the outer shell of the suit rested on the exhaust pipe causing it to melt onto the chrome pipe. I can't seem to find a solvent to remove it. Any suggestions would be greatly appreciated.

Thanks,

Chip,

Theoretically the PVC 'solvent'... which you can buy in most hardware stores ... should be OK. This is a high end solvent called Tetrahydrofuran and is the standard for cleaning PVC piping. There are much weaker solvents like Acetone [linked by editor to product info at Amazon] and MEK / methyl ethyl ketone but THF is the best. The store can may not contain a pure colorless liquid but tinted blue ... worry not, the blue is to help plumbing inspectors to check that primer, sic. solvent, was applied prior to cementing.

Mind you, there's another way ... heat up to around 550 degrees and at that temperature the PVC should burn off! I've never tried that approach but that's the temperature, I believe, that PVC, the type l rigid top-of-the-line material should decompose at ... your material being of a lesser grade and would need less heat, one presumes. But I'm not sure that the chrome wouldn't also 'discolor' at that temperature.

Cheers!

The old fashioned acetone nail polish remover worked for me.
