I have around 40 kg of self indicating silica gel ( being chucked out by a customer due to their interpretation of new health and safety regulations; the indicator chemical is toxic, but securely bound up in the silica gel. I saved them £400 ( £10 a kilo) by taking it away ! At the same time I helped them by removing 50 litres of concentrated hydrochloric acid that was past it's shelf life. Great brick/ prop,/drive/ alloy wheel cleaner when diluted down. I can't imagine why there was a ever a shelf life indicated for it at all, in never "goes off" !.
I put in 10 kg of regenerated silica gel every 3 weeks or so into the cockpit during our very wet and warm winters; no mould, no mildew, no smell. The gel in the more sealed cabin lasts longer
How do you "regenerate" it? Do you dry it in the sun? Bake it?
