in water sulphuric acid 10%

1. On treatment cards, give more detail re cleaning method, electrolysis conditions,concentrations, numbers of changes, method of rinsing, numbers of coats, etc. It isnot necessary to use exactly the same works on the treatment card and you can usemore concise ways of giving the information.For example, for copperalloy in BTA:

INHI immvac; BTA 3% in IMS; 10 mins +immer; 2 hrs

2. Treatment of an object with parts: If you want to write about two parts separatelydo a general treatment for the whole first (i.e. RMDU or RMSO) then go on toeach part. This is because there has to be a treatment entry for the whole object.for example:

RMDU whole mech; brushCONS wood brush; Par B72 10% in acetone4RMCO iron mech: scalpel, brush
