I'm a little paranoid about spores that can survive really long times and still be nasty.A rinse out with alcohol will get rid of some things (too bad you can't flame the alcohol off as that isn't good for the rubber). Although alcohol isn't good for some plastics and rubber, so that might weaken it depending on what material it was made out of.I had a spore that contaminated some buffers in the lab that survived through autoclaving, alcohol bath, and the flaming. Nasty bugger that was. I don't think it was something that would infect people, none of us got sick or anything, but the thing just Would.Not.Die. Tetracycline did kill it, funny enough, but all the normal things didn't even touch the spore.I guess some depends on Mom's health status and all, but if I were going to do it, I'd buy one new, they aren't that expensive rather than risk it.But that is me.K.
