Product data

How to use

500ml of MC2 will provide effective treatment for a typical 100 litre/ten radiator system. For larger or heavily fouled systems, use further MC2 as required.

To introduce MC2 to the system, we recommend using the MagnaClean® canister to dose the system. Alternatively, dose via a radiator or F&E tank.

For long term system protection use MC2 Silencer in conjunction with ADEY’s MC1+ Protector.

N.B. NOT for use in single feed indirect cylinders.
