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.
