Cleaning and sanitizing everything that touches your beer after the boil is probably your primary concern now as a beginning brewer, and going forward, as it is with all of us. Clean equipment like you are cleaning dishes that you will be eating from. I use diluted, unscented dish soap, same as I wash my dishes with. Get some brushes to clean tubing, spigots and small bits, bottles, etc. Soft cloths are needed for plastic fermenters, bottling buckets and other equipment that you do not want to scratch - scratches in your plastic equipment can lead to infected beer.
After you clean, then use sanitizer (I use Star San, there are other products),typically diluted in clean water, and follow the directions. Star San gets pretty foamy when it is shaken. Don’t fear the foam is a common term in brewing, meaning the foam from the sanitizer won’t have any negative effect on your beer.
When making beer, there is a lot of dishwashing that goes along with the process. Keep things clean and sanitized, and you are giving yourself a good chance to make good beer.
