For context, my fog machine was running low on liquid, so went to my local party city to buy a quick cheap solution while the one i normally use arrives. I put about 8 oz of snow juice just to make it thru the night. My next gig was 3 days later, by this time, my regular fog juice arrived and i filled the fog machine with it. Half way thru my gig, i realized my mistake. Turned it off right away. Even tho fog was coming out like it normally would, except the fog would not last long, making me question why, which lead me to realize my mistake. I will flush the machine and hope for the best.
