Note that he said cleaning and sanitizing. You cannot sanitize something that is not clean. Too many new brewers merely rinse and sanitize. That will not cut it for long. Get a cleaner you like and use it every time you use a piece of equipment to be sure that nothing is carried along that might cause infection of your system or beers down the road.
For example: Tubing is especially critical to rinse out, clean, rinse out the cleaner, sanitize, store (in a way that fully drains all liquid) and then sanitize before using.
