Alkaline cleaners are required primarily to degrease heavily soiled surfaces, including metals.


A typical formulation would be:

%

Lanphos TEP4K 10 Lansurf AE105 5 Potassium Pyrophosphate (50%) 20 Sodium Metasilicate 1 Preservative as required Water balance


Method of production -


1. Add the water and sodium disilicate and then mix

2. Add the remaining ingredients whilst mixing and then finally the preservative


In case phosphates cannot be used replace with a silicate or carbonate.
