Protocol K-280 is an organic salt based descaler that is designed to remove hard water scale and rust deposits in coffee machines. Protocol K-280 is formulated without detergents to prevent foam build-up and film formation. The organic salts used in Protocol K-280 act like hydrochloric acid without the safety hazards.
Product Directions
- For cleaning new coffee machines to prevent large scale build-up, add 500 mL of K-280 to the reserve water tank and flush the cleaning solution through the system.
- If the machine permits, allow the solution to sit in the machine for 5-10 min.
- After sitting, drain the cleaning solution and flush with water until the water tests’ pH is neutral with pH test strips.
- For cleaning heavily scaled coffee machines to remove large scale build-up, add 500 mL of K-280 to the reserve water tank and flush the cleaning solution through the system. If possible, allow the solution to sit in the machine for 5-10 min.
- After sitting, drain the cleaning solution. If time permits, recycle the spent cleaning solution back through the reservoir to maximize the amount of scale removed.
- pH strips can be used to test the strength of the cleaning solution. Once the cleaning solution has reached a pH of 4, it is spent.
- Drain the cleaning solution and flush with fresh water until the water tests’ pH is neutral with pH test strips.
