Appendix: How to Deep Clean Post Manure Contamination

A full-system deep clean strips back the biofilm, removes chemical build-up, and knocks out bacteria hiding in your plant. Think of it as the spring clean your dairy shed didn’t know it needed.

What You’ll Need

• Agmax Alkali and Agmax Acid

• Agmax Vat Cleaner (IF high foam is required)

• Hot water (85°C at the start of the wash)

• Bucket and brushes

• Gloves and safety gear

Step-by-Step Instructions

1. Manual scrub critical surfaces

• Manually scrub clusters that have fallen into cow manure, followed by associated jetters, and any other fittings that were contaminated, using Acid & Alkali at 3x the strength. I.e 100g sachets = 3x = 300g.

• If required: Use a separate brush for the milk line. Dirty brushes are bacteria bombs.

2. Flush the system

• Run cold compliant fresh water through the plant to remove milk residue. Don't skip this step.

3. Prepare your detergent wash

• Use Agmax Alkali first and then Agmax Acid - never both at once.

• Mix according to label instructions.

• Hot water must start at 85°C to be effective. Any cooler and you're wasting time and chemicals.

4. Run the Alkali wash through the entire plant with HOT water
If High Foam is required - use Agmax Vat Cleaner per label instructions with the Alkali wash. 

• Ensure all milking units, milk lines, claws, receivers and surfaces that come into milk contact with the wash. 

• Recirculate for 8 minutes or until your water temperature drops to 55°C.

5. Now, run the Acid wash through the entire plant with COLD water

• Ensure all milking units, milk lines, claws, receivers and surfaces that come into milk contact with the wash. 

• Recirculate for 8 minutes.

6. Rinse thoroughly

• Flush the entire system with cold compliant fresh water (5-10L per cluster). Don’t leave any chemical residue behind.
