Cleaning your kegs: How to use the Bucket Blaster?

1. The Bucket Blaster: What is it and how does it work?

Manually cleaning a Soda Keg or a PET fermenter requires elbow grease, long brushes, and plenty of water. The principle of the Bucket Blaster is to replace this human mechanical action with a high‑pressure automated closed‑loop system:

• The autonomous station: The system is built around a 15‑liter reservoir (a dedicated bucket) that serves as the base for your cleaning or sanitizing solution, inside which a powerful 2000 L/h water pump is submerged.
• The spray ball: The keg or fermenter is flipped upside down and positioned directly above the station on a vertical axis. The pump forces the liquid through a rotating stainless‑steel spray nozzle that projects powerful 360° jets against all interior walls, instantly removing yeast residue, krausen, or hop particles.
• The ecological closed circuit: The sprayed solution flows down the walls, falls back into the base bucket, and is immediately re‑circulated by the pump. This continuous recycling allows you to use a minimal amount of water and chemical product (such as Chemipro Wash or San) while still achieving deep cleaning.

2. Simultaneous cleaning of lines and Ball Lock ports

One of the greatest advantages of the Bucket Blaster lies in its ability to clean the invisible and inaccessible areas of your kegs—places traditional brushes simply cannot reach:

• Liquid and gas tee fittings: The kit includes additional flexible hoses equipped with Duotight quick‑connect fittings and Ball Lock connectors (one grey for gas, one black for liquid).
• Full disinfection from top to bottom: By connecting these fittings to the external ports of your keg while it sits on the station, the pump forces part of the cleaning solution to flow upstream through the dip tube and valve threads. Your connectors, internal seals, and service lines are continuously washed at the same time as the keg body.

4. The ideal protocol for a sparkling‑clean keg in 3 steps

To get the most out of your automatic washer, we recommend following this simple yet highly effective routine:

Step 1: Quick pre‑rinse

Before placing your keg on the station, give the interior a quick rinse to remove the bulk of loose yeast sediment. This prevents unnecessary contamination of your main reservoir and prolongs the effectiveness of your cleaning products.

Step 2: Hot wash cycle (15 min)

Fill the Bucket Blaster’s bucket with warm water (do not exceed 50°C when cleaning PET fermenters or kegs such as Oxebar or FermZilla to avoid deformation) and add your alkaline cleaner (e.g., Chemipro Wash). Position the keg, connect the Ball Lock lines, and run the pump for 10 to 15 minutes. The persistent spray will dissolve even the most stubborn residues.

Step 3: Final sanitizing cycle (5 min)

Empty the bucket, rinse it quickly, then refill it with cold water and a no‑rinse sanitizer (e.g., Chemipro San). Run the pump for 3 to 5 minutes. Your keg is now sterile, free of any microbiological residue, and ready to receive your next batch in a closed‑loop environment!
