How to descaling galvanized steel pipe?
Galvanized steel tubes will not rust in principle.... Batch rust with weak acid water immersion, individual can use steel wire brush brush on it.
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
