We've all been there -- you get out in the hot sun, or play a sport and you come back all sweaty.

In addition, over time sweat can start to make a stain on those clothes, making them unattractive to wear.
Less common, but also a problem can be removing sweat stains from upholstery and carpet.
These types of stains can occur if you sit down on your couch or carpet while you are all sweaty.
Here are step by step instructions for removing stains caused by sweat and perspiration:
Step 1: Assess whether the sweat stain is old or new. If it is old it may have started to change the color of the fabric because of the acidity of the sweat.
Step 2a: When removing an old sweat stain you should apply white vinegar to the stain, and let it sit for approximately 30 minutes.
Step 2b: If it is a new stain, then you should apply ammonia to the stain, and let it sit for approximately 30 minutes. (Be sure to test the ammonia in an inconspicuous area first to make sure it will not damage the fabric.)
Hint: Do not apply both ammonia and vinegar to the stain at the same time.
Because vinegar is a mild acid, and ammonia is an alkaline solution, they will just neutralize the effectiveness of both if combined together.
Step 3: Rinse either the vinegar or ammonia from the fabric.
Step 4: Apply a laundry prewash stain remover containing enzymes, or blot liquid laundry detergent containing enzymes onto the sweat stained area and let it sit for 15 minutes.
Step 5: Launder in the hottest water the fabric will allow to get out the stain caused by the sweat.
Hint: Make sure the stain is gone after washing, but before you place in the dryer or you may set the stain. Repeat if necessary.
Step 6: For really stubborn sweat stains you can also try relaundering with either chlorine bleach, if safe for the fabric, or color bleach if not, in the hottest water also safe for the fabric.

Step 1: Mix a solution of two cups cool water, one tablespoon dishwashing liquid, and one teaspoon of either vinegar or ammonia.
Hint: Do not use both ammonia and vinegar, just choose one, because if you combine them they will neutralize each other's stain fighting characteristics.
Make sure if you choose ammonia that you test, in an inconspicuous location, for color fastness on your upholstery. (Click here for more information on how to clean upholstery.)
Step 2: Using this solution, sponge the stains caused by sweat with a clean white cloth.
Step 3: Next, blot at the stain until the liquid is absorbed.
Step 4: Repeat steps 2-3 until the sweat stain is removed from the upholstery.
Step 5: Now that the stain is removed you should get plain cold water and a new white cloth and sponge the area to remove the cleaning solution, and then blot dry.
Hint: Be sure to get the upholstery only as wet as necessary to remove the stain.
Step 6: If the stain still remains blot at the stain with rubbing alcohol.
In the unlikely event that you get sweat stains on your carpet the instructions for sweat stain removal from carpet is the same as for upholstery.
