Is drain cleaner safe for galvanized pipes?

When dealing with clogs in galvanized pipes, skip the harsh chemical drain cleaners like Drano or lye, they speed up internal corrosion and can lead to rust and leaks over time. Your best bet is to stick with mechanical solutions such as a plunger or a drain snake/auger, or opt for enzyme-based cleaners, which break down organic buildup gently without harming the metal.
