Now that it’s winter - at least in the Northern Hemisphere - static electricity becomes even more of a challenge. There’s nothing more depressing than to pick up a loved and carefully crafted robot, only to feel a multi-thousand volt bolt of electricity fry it’s sensitive electronics.
Commercially prepared anti-static spray can be had, but it’s expensive.
Anti-static spray can be made very cheaply from liquid fabric softener, (which you may already have), water, and a spray bottle.
All you do is mix about 10-15% fabric softener with warm water in a spray bottle, and there you are!
Spray liberally over any surface that is a potential static generator.
Since fabric softener is, essentially, a perfumed fat solution, it can be very slippery and somewhat conductive.
Avoid spraying on smooth, potentially slippery surfaces and avoid spraying electronics with it.
