Lies, all lies. The so-called Apollo toilet brush was actually a movie
prop filmed in a soundstage in Arizona.

Ironically enough, the only real Apollo spin-off in widespread use is
the modern low-flow flush-twice toilet, whcih was developed to meet the
plumbing demands of the huge film crew in the parched Arizona desert.
The cargo saucers they used to bring water from area 51 didn't have
enough capacity to allow 10-gallon flushes, so people were asked to
either use the urinals only or to hold it as long as they could.
(That's the real reason there were no female astronauts.)
