What it is and what it does. Steel degreasing powder is the powdered alkaline cleaner used for soak and electro-cleaning of steel hardware before pickling and plating.
- White to off-white powder; normally used at 20-50 g/L in water.
- The blend of alkali builders, surfactants and chelating agents saponifies oils and lifts shop soil from the surface.
- Powder is cheaper to freight than the liquid concentrate, which is why most export customers order the powder.

Buyer Questions We Answer Every Week
| Question | Answer |
|---|---|
| Which polarity for electro-cleaning steel? | Cathodic for a short time followed by an anodic flash is the usual sequence; the exact cycle depends on the part. |
| Can it be used for zinc die castings? | No - the strong alkali attacks zinc; a dedicated die-cast cleaner is required. |
