You might be surprised to see that many ingredients act as great rust removers. It is about choosing the correct one for your fabric type & the intensity of the stain. For example, if you wish to remove rust stains from white shirts & t-shirts, lemon juice is the best. But for colored clothes, lemon juice will be a nightmare owing to its bleaching property. For colored cloth, vinegar is a good option. It is less abrasive on the color of the fabric as compared to lemon juice. Not only this, but vinegar is excellent for old stains as well. Besides these, you can also use WD-40 Multipurpose Product for removing rust stains on fabrics like jacquard & jeans. WD-40 MUP is an excellent rust remover and, therefore, will help in this regard too. We always recommend conducting a small patch test to be safe.
