OK, maybe Johnson didn't have this use in mind for their baby powder.
But, it can help to pinpoint the origin of leaks. This is particularly true
if there's a leak and the source is not obvious. Baby powder is an
inexpensive readily available substance, however it will not change
colors when it absorbs fluid like Met-L-Check D70, a leak detection
powder that some car manufacturers recommend to help verify
automotive fluid leaks.
After all a correctly diagnosed leak on the first attempt, saves warranty
costs for the dealers. Occasionally in the past, I used baby powder to
help determine what was causing a leak. I remember once I was checking
a fuel leak near the fuel rail. It was really hard to trace where the leak
was coming from. It wasn't spraying, more of a quick saturation when
the vehicle was started. I would dry the engine off, but by the time I
would start the engine and go around to the engine compartment to
look for the leak, the fuel would saturate the top of the engine making
it difficult to pinpoint where it was leaking from.
I dried the engine off with compressed air one final time and sprinkled
baby powder in the area of the leak. (I always kept baby powder around
for re-using latex gloves, since it allows them to slip on easier) So with the
baby powder on top of the engine, I was ready to start the vehicle once
again. An auto technician I worked with was walking by, I explained to him
I was looking for a leak, so had him watch while I started the engine.
What he said next struck me as funny, when he peered closely checking
for the leak, he said "smells like baby powder."
