Simply tossing your white clothes into the wash with a laundry detergent specially designed to get rid of stains is probably the easiest way to get rid of yellow stains. Wash your clothes in the laundry as you normally would with the stain-removing detergent to remove the stains in 1 step.  There are a lot of detergents on the market that will not only remove your stains, but also leave your clothes smelling terrific! You can find laundry detergent designed to remove stains at most grocery stores and mass retailers where detergent is sold. Add the capful of bleach to a load of white clothes along with detergent to remove stains while also improving your clothes' overall shine. However, make sure your clothes can be safely bleached before you wash them this way. Avoid bleaching colored clothes or delicates, as the bleach might damage them.  You can check to see if your clothes can be safely bleached by looking at their tags. If a hollow white triangle is on the tags, this means they can be safely bleached. If the triangle has diagonal stripes in the middle of it, those clothes can only be treated with non-chlorine bleach. If the tag on your clothes contains a solid triangle with an X on top of it, that means they cannot be bleached at all. Bluing agent adds the slightest hint of blue to your clothes, which actually combines with the yellow hue of your stains to make them white. Mix the agent with cold water, per the instructions on the bottle, then toss it into your laundry machine with the detergent and the stained clothes and wash them as normal.  You can buy bluing agent at any department store or grocery store that sells laundry detergent. Note that bluing agent isn’t actually a cleaning agent, so although it will offset the yellow hue of your stains, it won’t do anything to make them cleaner. Borax is a naturally occurring mineral that helps to remove stains from clothes and even deodorizes and brightens them. Add 0.5 cups (120 mL) of borax to your laundry along with detergent at the beginning of the wash cycle to wash clothes with odorous stains. Borax is also a great multipurpose cleaner you can use to clean the inside of your car, your pet’s bedding, and even the washing machine itself! If the stains on your clothes were caused by rust, there are a number of commercial products specifically designed to remove rust that you can use. Simply add the rust remover to your washing machine as it's filling with water and let the clothes soak in it for 5 minutes. Then, add your detergent and wash the clothes as normal.  Be sure to follow the usage instructions on the bottle very closely, as rust remover fumes can be dangerous when inhaled. To best protect yourself, wear rubber safety gloves when handling rust remover.
