Use a rust removing oxalic acid or acetic acid. Prepare a mixture by taking 1 teaspoon per cup of acid water. Then heat the solution and not boiling, remove from heat. Add in a little solution of ammonia and a pinch of baking soda. Briefly dip the cloth with a spot in the liquid and rinse it thing. If the rust is not gone immediately, repeat the procedure several times.
To remove the stain with a white cloth, use sodium hydrogen sulfite, taking 1 teaspoon per cup of water. In solution, heated to 60 degrees, lower the contaminated area of clothing for a few minutes. Then rinse in warm water.
For colored fabrics, this method is not suitable rust removal, as hydrosulfite can discolor them. It is better to use a mixture prepared from white chalk, glycerol and water. These substances should be taken in equal quantities, mix, apply on the stain and leave for a day. After this thing should be washed.
You can display the stain with white cloth, plunging it into a two-percent solution of hydrochloric acid. Should hold up as long as not descend spots. Subsequent rinsing things should be done in water with the addition of ammonia (three tablespoons per gallon of water).
Try to get rid of the rust stains, moisten the area with freshly squeezed lemon juice and then ironed with a hot iron. When ironing, be sure to lay the fabric between the surface of iron and clothes. Then again, wipe the dirt swab dipped in lemon juice and rinse with warm water.
