I just mixed up a batch of hand sanitiser for some family members.
It's just a mixture of 99% isopropyl alcohol and aloe gel. Many model makers will already have the alcohol, I've got almost a litre of the stuff and the gel is till readily available.
It's a LOT cheaper than the branded stuff, assuming you can still find it.
You need to end up with more than 60% by volume alcohol, the maths isn't difficult and it doesn't need to be precise.
