Scalemaster SM4 Sludge Remover Concentrate 250ml 500454

Description

Scalemaster SM4 Sludge Remover is designed for the regeneration of established central heating systems, helping to restore circulation and system performance by removing black iron oxide sludge and corrosion products. Added to the system and circulated during normal heating operation, SM4 works by loosening and suspending contaminants so they can be effectively flushed out. Supplied in a 500 ml bottle, it treats systems up to 100 litres (10 radiators) and is compatible with aluminium components. The formulation is safe to overdose (up to double dose) and can be mixed with other Scalemaster products, offering flexibility during servicing and remedial work.
