De-misting a sand blaster window

My Guyson sand blasting cabinet is excellent, but the perspex window
constantly mists up externally from my breath. Especially  in the
current cold weather it becomes a right pain, but even in more normal
times it's a problem. I have thoughts of installing some sort of
blower to give a cross draught, possibly with a heater, but cannot
find anything small enough not to be cumbersome.

Any suggestions welcome, but lets not start a heavy breathing thread!

Isn't there something that you can spray on to prevent misting like
motorcyclists use to prevent their visors fogging?
I'm thinking vaseline, but probably wrong...

Washing up liquid, wiped on then polished off is what I use on the
visor.

I have a couple of 24v dc 0.33A tangential blowers. Outlet is 210mm
wide by 25mm high. Fan is about 40 diameter. Overall mount area about
25 x 100 weight 400g. If any good you can have one for the postage.
They are ex photo copier.
I am in Cheltenham.

I would have thought a computer fan would do the job. Something off an old
power supply or cpu. My video card even has a diddy one mounted on it.

A little neat washing up liquid rubbed on stops the misting for quite a
while. Isn't that what posh divers use on the inside of their goggles -
common ones use spit :-)

In the early days of high speed experimental jets the Yanks used Drene
shampoo.
I wonder if it's still available :-))

I have some of the hydrophobic liquid (I can't remember the name and the
label is missing, so not a good sales pitch) designed for car
windscreens, shower doors, binoculars etc. If you want I can stick a
small vial in the post for you to try.

but washing up liquid may work just as well, that's what I used to use
on my visor.

Something like a motorcycling mask, so your breath is diverted down
towards your neck, rather than straight forwards at the visor?
