How to use
500ml bottle 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 the F&E tank. For long-term system protection, use
MC2 Silencer in conjunction with ADEY’s MC1 Protector.
Also available in the following sizes: 300ml, 5L, and 10L.
Do not use in single feed indirect cylinders.
