I use dishwashing detergent to clean all of my equipment. To sanitize I used to use One Step, which works great, but can react with copper tubing if you need to sanitize a counterflow wort chiller. So I switched to Iodiphor. It is cheaper than one step and can be purchased in large amounts. The food industry has been using Iodiphor for many years as a food grade sanitizer. You just add one ounce per 5 gallons of water, soak your equipment or fermenter and allow to air dry for a few minutes. If you do not let it dry then some say it may impart an off flavor, but I have never had a problem. If your copper tubing starts turning green then run distilled white vinegar through it an let soak overnight. You can also boil any materials that will not melt for 15 minutes. The most importany thing is to not let your sanitized equipment come in contact with any unclean surface.
