I have most certainly heard of this. Both those products are 
extremely powerful oxidants. I don't think they'll attack 
polythermaleze insulation, but rubber and some types of plastic 
would definitely be at risk in my opinion. Then there are uncovered
solder and wire joints not to mention the laminations if unprotected.
Seems to me the blower/sucker outlet should bypass the motor itself.
