Puzzled

Sprayed the roof with the moss killing stuff. According to the blurb the spray unit can reach an incredible height, ie to the top of a two story house roof. Well ours is a bungalow and even with the water turned fully on, it definitely did not reach the top of our roof. Had to get the ladders out and spray off them.
The blurb says that one should wear eye protection and a face mask. So being a good little boy I got out the face mask and the goggles. 2 seconds later I was as blind as a bat as the goggles steamed up before I had even begun. How DO people manage to use these things without them fogging up when you breathe?

Goggles can be a pain, especially if you wear glasses. Always steam up.

Try getting goggles to room temperature first.

^^^unless OP keeps his goggles in the fridge, aren't they going to be rather warm anyway?

Ventilated goggles, Palustris...

Always had this problem with the face masks too. We are putting down insulation in the attic and it is best to wear a face mask, but my glasses steam up instantly, even when wiped over with the anti-misting stuff (ie dish washing stuff!).
Found a solution, let my wife do it, she does not wear glasses.
