I am going to make one of these. Thanks for the pic. I will probably make a smaller one; maybe 10 holes by 2 holes.
I usually wash 12-18 bottles at a time and let them dry. When they are dry I tear aluminum foil into small squares, about 3"x3" to 4"x4", and cover each bottle. Then I feel better about storing them for a while. When I want to sanitize I just fill the dishwasher with bottles. I don't use any soap, and I turn the heat-dry on. I checked the dishwasher with my probe thermometer, and it reaches over 170F, which I believe is enough to sanitize. I haven't had one problem, yet. When the bottles are cool I just sit next to the dishwasher and bottle right from there. Works like a charm.
