I was told to use
I was told to use the sponges from the auto parts store?
Stopped by an auto parts store today .... they have about 7 different styles of sponges. None really had the look of working. I've tried many over the past year and find the cheap ones work best. I parted with $26 for 10 humidity pads (sponges) while picking up the all plastic door for my 1502 GQF. Have installed it...............love being able to see into the incubator so well. (-:
