Cleanliness and sanitation are extremely important to the brewing process. It’s an indisputable fact that you can’t make good beer with dirty or unsanitary equipment. PBW, or Powdered Brewery Wash, is an environmentally friendly alkali cleaner and it's widely considered the gold standard by commercial and homebrewers for cleaning brewing equipment.
We have a lot of experience brewing beer at home. In fact, we just had a brew day here at the office and in this tutorial, we’ll be showing you the steps we took to clean our brewing equipment with PBW. Specifically, we will be cleaning our 10 Gallon 120 Volt Brewing System but this process can be used for our 240 volt 20 gallon system as well.
Cleaning Vs. Sanitation
Before we explain how to clean brewing equipment, it's worth noting why it's so important. Preparing a brew system for making beer is a two part process that first involves cleaning and then sanitation. Cleaning is the process of removing debris from the equipment. Sanitation is the process of eliminating microbes like wild yeast and bacteria. If cleaning does not happen first, sanitation will not be effective.
How To Clean Brewing Equipment
We actually clean our brew system after every batch of beer. That's when it's easiest to clean because debris has not hardened yet. It's also the ideal time to clean because storing dirty brewing equipment can lead to all sorts of problems.
You'll need a few items for this process. We suggest the following:
- Gloves and goggles
- Dirty brewing equipment
1. After a brew day, drain any remaining wort from your equipment and rinse it with water. Reconnect all your hoses after rinsing.

2. Fill your brewing kettle with water. We filled our 10-gallon kettle (37.9 liters) with 7 gallons (26.5 liters) of water - if you’re using a 20-gallon (75.7 liter) kettle fill it with 14 or more gallons (53 liters).
3. Put on safety goggles and gloves - you may notice we did not do this, but safety equipment is always recommended when handling cleaning chemicals.
4. Weigh out 1-2 ounces (28.3 - 56.7 grams) of PBW for every gallon of water - for our 7 gallons of water we weighed out 10.5 ounces (297.67 grams).

5. Pour this into your brewing kettle and heat water to 130° - 180° F (54.4° - 82.2° C).

6. Turn the pump on and recirculate your PBW solution for one hour.

7. After one hour, empty the PBW solution from your equipment and replace it with an equivalent amount of freshwater.
8. Heat the clean water to 130° - 180° F (54.4° - 82.2° C) and recirculate it for an hour as well.
9. After recirculating hot clean water for an hour, you’re brewing equipment is ready to brew another beer!
Extra Step: Recirculate a Star San solution after these steps in order to sanitize your equipment. Even though boiling wort can sanitize your brewing equipment during the brew day, it can only help to sanitize beforehand.
