Sentinel X400 High-Performance Cleaner is specifically designed for cleaning older central heating systems. It is a non-acid treatment which restores circulation to radiators and pipework. Its ruthlessly efficient formula shifts built-up magnetite sludge, eliminating cold spots in radiators and restoring proper heat distribution. Use the Sentinel X100RD to treat the system for limescale and corrosion. It works effectively as a boiler descaling chemical, helping to keep internal surfaces clean and free from mineral buildup.
