This concentrated central heating cleanser from Wiseman helps to restore heating efficiency by removing sludge, limescale and flux residue from central heating systems. It also prepares heating circuits prior to introducing inhibitor solution. 1 bottle of Everad central heating cleanser is enough to clean and preserve 100 litres of system water, but it mustNOTbe left in the system!

• 500ml bottle concentrate
• Will clean and preserve up to a 10 radiator heating system
• Overdosing the system is not a problem
