Why 304 Stainless Steel Can Show Rust Marks During Renovation (Even Though It Doesn’t Rust)
304 stainless steel is a high-quality material known for its shine, strength, and resistance to rust. That’s why it’s widely used in sinks, taps, and kitchen products. However, during renovation, rust marks can still appear. Here’s why:
-
Dust from Other Metals
During drilling or cutting nearby, tiny iron particles can settle on the steel surface. These can oxidise and leave rust marks. -
Chemicals in the Air
Fumes from paint, glue, or cleaning agents may react with the steel’s surface, causing temporary stains. -
Glue or Cement Splashes
If these materials sit on the surface too long, they can trap moisture and result in rust-like marks.
The Good News
These stains are usually only surface-level. The actual stainless steel underneath remains strong. Use a proper stainless steel cleaner to remove them.
How to Prevent It
Cover your stainless-steel products during renovation and wipe them clean once work is done. That helps preserve their shine and keep rust at bay.
