PRELUDE ACPR HD is a concentrate mixture of surfactants, sequestrants and caustic alkali and is particularly effective in cleaning ferrous parts in immersion tanks but it is also capable to remove oil, grease and some air-dried paints of internal combustion engines that have become heavily contaminated in service, e.g. valves and cylinder heads.
 
BENEFITS
PRELUDE ACPR HD cleans metal parts which are heavily contaminated with carbon, paint, rust and lead deposits.
