Hard·⏱ 20–40 min

  1. Apply lemon juice directly to the rust spot on the carpet.

  2. Sprinkle table salt over the lemon juice.

  3. Let sit 30 minutes — the citric acid dissolves iron oxide.

  4. Rinse by blotting with cold water on a clean cloth. Blot dry.

  5. Repeat once if needed.

Pro tip

Rust on carpet usually comes from a wet metal object (furniture leg, can, bracket). Commercial rust removers are significantly more effective than home remedies on carpet.

⚠ Warning

Commercial rust removers are strong acids — rinse completely. Test on a hidden area first.

Always check the garment's care label and test any solution on a hidden area first. StainsGone provides general household guidance, not professional textile or restoration advice.
