Gently scrape the rust spot with the edge of a teaspoon to remove loose pieces of rust. Work gently to avoid damaging the fibers in the fabric.
Thoroughly saturate the rust spot with lemon juice.
Liberally sprinkle salt over the lemon juice. The salt and lemon juice create a chemical reaction to remove the rust.
Let the lemon juice and salt sit on the stained area for 24 hours. This gives the chemical reaction time to loosen the stain.
Press absorbent toweling on the stained area to lift the stain out of the fabric. Do not rub, as this can damage the fabric.
Run cold water over the stained area to remove any residual rust.
If the stain is not completely gone, apply more lemon juice and salt, and repeat the process until no stain remains.
