If temp is below freezing I would suggest wings and stab are a far bigger potential problem than the windscreen.
Agree, but at least that you can scrape off, something you can’t do with the windscreen w/o scratching it.
You will damage the paint though.
@172driver: can you be more specific? I fly a C210 in Africa regularly but cannot recall it stating specifically that TKS cannot be used. Might not have been my focus reading the POH with the high temps out there. As the TKS fluid is spayed on the glare shield anyways in other aircraft such as the Cirrus SR22, I would not know how it could damage it. It for sure works to remove it.
Removing a small bit of ice. Seneca 2-200T, parked at Lyon Bron.
Removing ice from Cirrus SR22T.
I find it hard to understand how TKS fluid can keep the ice off an aircraft in flight yet damages it when used on the ground.
I expect the prohibition is due to the lack of hold over time data in the ground de-icing role and keeping the lawyers at bay.
Sunlight.
PS. If TKS damages it, why do I have a deicing system that pumps TKS over the windscreen?
@AeroPlus, I am somewhat puzzled by that as well, that’s why I’ve been asking here. See below from the C210 POH (C210L, Centurion II):
NOTE
Never use gasoline, benzine, alcohol, acetone, carbon tetrachloride, fire extinguisher or anti-ice fluid, lacquer thinner or glass cleaner to clean the plastic. These ma- terials will attack the plastic and may cause it to craze.
NB: in the original text the ‘Never Use’ is underlined.
While I have flown in sub-zero temps, these situations were all in very dry climates, e.g. here in the deserts and in southern Africa.

Goodness Gracious Peter!
At this rate we are all going to end up speaking proper English!
@172driver: strange. I would think TKS fluid can be used as can be seen from this info.
@172driver: technically speaking the windshield might be off limits to TKS, so don’t shoot the messenger. :-)
