Some alkaline tolerant organisms can survive. pH 12-14: Very few organisms can survive at this pH.

10 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Let’s do some Acid! (Cleaning, that is). Acids that can be used for beverage processing equipment cleaning: Mineral Acids (Hydrochloric, Phosphoric, Sulfuric) Oxidizing Acids (Nitric, Peracetic Acid- PAA) Organic Acids (Citric, lactic, acetic) Phosphoric/Nitric acid blends Nitric/Phosphoric acid blends Surfactant Blends Normally Proprietary, Check with your supplier.

11 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Big Key To Remember with Acid First and Detergent ONLY cleaning: Keep your pH preferably in the range of for optimum performance.

12 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Fermentation Vessel CIP (using acid and detergent only) The test was performed in the following manner: Acid Wash: 3% as supplied nitric/phosphoric blend & 0.25% detergent additive – 20 minutes Rinse Cycle PAA Sanitation

21 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Filler Bowl, Tap Line Cleaning If beerstone is a problem, try this approach! May not suitable for brass and other soft metals (do not pack brass faucets with the cleaning solution, stainless is OK). Dirty tap lines are a huge issue in bars and restaurants.

22 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Why Use a Detergent Additive? Better Soil Wetting and Penetration (Compared to Using Acid Alone) Better Soil Removal (Protein Displacement/ Dispersion) Better Rinsing with a properly formulated detergent additive

23 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Why Use Nitric/Phosphoric Acid Blends? Nitric is an oxidizing acid, extremely effective on organic soils. (Beerstone contains protein). Nitric is a passivating acid to stainless steel Phosphoric “tames down” the nitric and holds pH Recycles well, and can be easily neutralized and sent down the drain.

24 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Pros of acid first and detergent only cleaning: Acid and Detergent Recycles Well Saves CO2/unaffected by C02 in the keg or tank Better at removing and preventing beerstone formation Can reduce DO level in subsequent beer in bright tanks Cons of acid first and detergent only cleaning: May not be as effective on protein soils Make sure the detergent blend works! Need good spray nozzles, preferably spinning type Caution – acid is tough on untreated concrete!

25 Copyright 2011 Birko. All rights reserved. Acid and Detergent ONLY Cleaning Conclusion: Acid & Detergent ONLY Cleaning can be not only less expensive in terms of use cost, it is proving to be more effective in removing and keeping beerstone from forming in secondary FV’s,kegs, brite tanks. Overall product quality can be improved (less DO in the beer and no flavor profile issues. Don’t work harder-Work Smarter! (Shhh: X-Puma has “bits of real panther in it!!!. Just kidding.)
