I want to begin my first batch but I know sanitizing is really important and I don't want to make mistake about it, so I read How to brew - Everything you need to know to brew great beer every time and it is written about sanitizing with Star San:
No-rinse. Can be used via immersion or spraying. Will sanitize clean surfaces with 30 sec. contact time.
So, I went on Brouwland to make my order and I saw about the product:
Prepare a solution of 15 - 25 ml Star San HB™ per 10 L of water. Apply on surface with a cloth, mop, sponge, spray or by immersion. Spray 15-20 cm from surface and rub with a brush, cloth or sponge. The surface must remain wet for at least 1 minute. Rinse with water of the same temperature.
There are differences about time and rince. About the time, I guess it is not really important and I can wait 60 seconds without risks. But about rince: should I do it or not?
To finish and add some confusion, Five Star edits a cleaning guide who says:
Your equipment is ready for use immediately after removing the solution.
