It's not as easy as just rubbing a lemon on the stain. You have to also add rock or sea salt to the half of a lemon and work that into the stain. Then, take outside on a sunny day and allow to set in the sun for awhile. Then launder. but, because you already dried the pants, you MAY have to do this process again. But, it should do the trick. Addition: The rust stain removers for fabrics in stores are for WHITE fabrics only. It will damage colors.Can you still get rust stains out of clothing after being washed and dried? If so, how?
Whink, in a small brown bottle in the laundry aisle.





Yes, it might change the color, but I've used it for 20 years and have never seen any changes on any fabric I've treated. The directions say to ';try in an inconspicuous place';
you can buy a rust remover for fabrics at walmart. Its cost $4-5 and will still work after being washed and dried. Look in the cleaning chemicals aisle
i used the lemon juice trick and it worked afterwards, just remmember to sprinkle salt over the juice and lay in the sun.
