What about anything higher than 91%, would that work? Curious because I have access to IPA at work
I don't think it's a problem to use something with a higher content, if you have convenient access to it. 70% and 91% are the two types most easily acquired at the local drug or grocery store. Between those two the 91% is the way to go. I did briefly look into buying from a supplier so that I could get a bigger volume, by the gallon. It can take a lot of alcohol to fill the size tub needed for an O scale loco or car. You can get a funny look or two when you checkout with 20 small bottles at the store.
For the tub, I just used a plastic storage container. But another good idea is a wallpaper hanger glue trough. It's the right shape for O scale type stock. But no lid, so I would cover it with plastic wrap or similar to prevent evaporation.
It would appear that 99% costs about 4 times as much as 91%, based on GRJ's link, but if you have it at work then that's not an issue.
