Was the first space toilet brush developed on the Skylab?


Way before then - the brush that turned up on Skylab was actually a Gemini
model, though not a flown item.

In 1969, an Apollo-era space toilet brush was used as an improvised APS ARM
circuit breaker prior to Eagle's lunar lift-off. The year after, during the
flight of Apollo 13, it became apparent that the CM and LM brushes were
incompatible (the CM brush being designed for a square hole), and a
jury-rigged adapter had to be created on the fly. Additional LM brushes were
carried on subsequent flights.

There are doubtless many other such stories.
