Wow. Everybody is entitled to their opinion, but people who have no chemistry understanding beyond reading a label should not be offering chemistry advice, especially not telling you everything will be ok.

HCl does not magically neutralize, it REACTS with something, possibly your rope.

HCl is a gas, it doesn't need to spill to cause damage.

"HCl is a gas"

I understand.
In the case of Scotchie's situation - I felt that any concerns about corrosion from gas/vapors were mitigated by the fact that three of the ropes were in bags (therefore very poor air circulation) and the exposure time was very short. Hence any HCl that might have touched the rope sheath could be washed off, and corrosion effects would be negligible for a very short time.

I would feel completely differently if the ropes had been in the storage shed for a prolonged period of time - months or years.

Thanks for posting that link. It was a very interesting read.
I find it quite puzzling that two of the chemicals with
significant effect on the Dyneema in the 3-hour soaking
with 15-min. drying
--viz., acetone & vinegar, weakening resp., 17% & 20%--
had NO weakening for a 72-hr soak and complete? drying!?
Huh?
Sounds like melting, which IIRC, weakens polypropylene
but after cooling the strength remains!?

In reply to:
BTW, in case anyone who climbs with me reads this thread, the ropes were retired and my wife bought me a new one. Problem solved. Thank you honey!

But the questions remain. As I suggested above, it would
be nice to test the unbagged rope; if that is fine,
surely those in the bags must be so --and you'd 3 of them!
