Water = 25

General Metal CleanersRecipe 2 :

Phosphoric acid = 15-25 parts
Ethylene glycol monobutyl ether = 7-20
Water = remainder

General Metal CleanersRecipe 3 :

Sodium acid pyrophosphate = 16.5
Sodium bisulphate = 80

General Metal CleanersRecipe 4 :

Sodium sulphate (anhydrous) = 15
Sodium melltsilicate = 40
Sodium sesquicarboflate = 35
Tetrasodium pyrophosphate = 4
Xynomifle powder 20 = 4
Sodium alkylnaphthalcne sulphonate = 2

For soaking or electrolytic cleaning of ferrous metals use 4-6 oz/gal of this solution at l85-200°C.
For soak-cleaning of aluminium and zinc alloys use 2-4 oz/gal at 165-175°F.

General Metal Cleaners Recipe 5 :
