After tasting some of my wine my neighbor wants to give it a try as well. He was excited about getting about 200 bottles for free. They were rinsed after use but stored upright and have a few spots of mold in them. Anyone have any ideas how they can be cleaned? I was going to use a mild bleach solution like I have in the past for beer making but I just read in a wine making book never to use any type of bleach near any type of wine making equipment as it can cause an entire infection in your cellar area that you may never be able to get rid of and can infect your wine for years because it becomes airborne. Anyone heard of this and have a good way to clean bottles? Thanks in advance, Ken
