When it comes to brewing sanitising and cleaning is nearly half of your work. Sanitising is important to make sure that your beer comes out tasting great and without any unwanted off flavours and infections. You need to make sure that everything that touches and holds your beer or wort is clean. Including the smallest of utensils and accessories including spoons, scissors, brew bags, droppers, measuring cups, thermometers, hydrometers to the larger ones like your boiling pots, mash-tuns, fermenter, bottles, bungs, grommets, crowns-crown capper and so on.
1. First off, wash all your equipment sparkling clean with warm water and unscented dish soap(you don't want your beer to smell "Lovely Lavender" or "Morning Fresh"). A Vim lemon dishwash soap is still OK, but rinse well with water after wash.
2. Use 2.5ml Povidone Iodine per liter of clean drinking water(RO water is your first choice or add 1 teaspoon of vinegar per liter to the water). Make sure to use the the exact amount. Use a dropper with markings on it for this purpose. You can get droppers from any medical store(it might require you to buy some cheap medical drops but consider it a one time investment).
3. Soak a rug or clean cloth into the sanitising solution and wet wipe all your equipment and then the surface of your kitchen counter or the place where you're planning to brew. Make sure it touches every inch of your equipment to be certain its sanitized.
- You can rinse bottles or fermeneters with narrow mouths with the solution. You don't have to discard the solution after rinse, save it in a closed container. You can use it over and over for 48 hours.
- Keep the cloth drenched so that it leaves a thin coat of liquid on the surfaces after you wipe. (This is necessary since it needs 2 minutes of contact time to kill all the bad bacteria and microbes)
4. You must not rinse your equipment with water before brewing(this sanitiser is foodgrade, so if a few drops end up in your brew it wont harm).
5. Make sure you touch your equipment with very clean hands(use any antibacterial handwash to wash your hands when required) and nothing else touches it until you're done using it.
X. Follow this procedure everytime you brew. All for brew... Merry times!
