I recently did some night hunting and took the enviro cover off to enhance the night light. It was dark and I sprayed on some bug spray on myself - some of the mist drifted onto my racer screen - it was dark so i didn't notice at the time - well the next day I noticed the plastic screen is all spotted where the bug spray hit it. I am sure this is not the first time it has happened to someone. Anyone know what I can rub on the screen to lessen the effects of the spotting?
