Can't say I've had that problem. I've got a small (50ml) spray bottle of
the sort you can buy at Superdrug for well under a pound. It's used
nearly every day with 100% isopropanol and has been going for at least
10 years. I didn't expect it to last more than a few months, but it has
certainly surprised me with its longevity.
