I have a #3 and the racks won't fit it any sink that we have nor the dish washer. I put them in a large black contractors bag from Home Depot. I open the bag completely and slide the racks to the bottom, add enough hot water to cover the racks,with the racks laying flat, so only a inch or two of water, put in one of the dish washer pods (Finish I believe) then I pull the bag up around with the racks flat on a patio table, I put a small bungy around bag and let them lay in the sun till I get back to them, a few hours or a day or two. Living in Arizona, even in the winter, the solar effect on the black bag heats the water through the day. Everything comes off real easy, even smoke stains. Easiest way I have found for the larger racks.
