How long will the glasses stay unfoggy before they have to be sprayed again?

With this product, cleaning your glasses once before starting the day helps you to use your glasses all day long, even with a mask on. I can also say it is very effective in cold and foggy weather.

I work in a freezer at 20 below will this work on my glasses?

Im very confident it will Not work in temps like that. Then again ive only ever used it in the heat or temps around 70 degree’s

Is this safe to use on “heated” snowmobile helmet shields?

Thank you for your question. This product has been tested effective on Face Shields to prevent fog build up BUT not specifically "heated" snowmobile helmet shields.

I'm very happy with how well it prevents my glasses from fogging while wearing a mask. I would like to know how to clean the micro-cloth?

Thank you for your question. For cleaning your microfiber cloth, they are machine washable but please do not use Fabric Softener.
