Wash Cold - Heat is the enemy of the performance lycra fabric used to create your singlets. You should wash in cold or warm water, never hot water.
Use Mild Detergent - Use a mild (non-phosphorous) detergent. Harsh chemicals can cause bleeding or fading of colors.
Hang Dry - Avoid hot dryers & remove the singlet as quickly as possible from the washing machine, allow it to drip or hang dry away from sunlight. Don't use metal hangers, they can leave rust marks.
Presoak It - If your singlet has bloodstains, presoak it with a little laundry detergent. Soaking for at least one hour will help loosen any stains before washing.
Lose the Stink - Let's face it - singlets get stinky. If you have a singlet that has got the funk, add up to a cup of baking soda to your pre-soak, it will go a long way to removing odors.
No Bleach - Never use chlorine bleach - it will damage the fabric and dull the vibrant colors sublimated into the fabric.
Wash Alone - Wrestlers compete alone, and their uniform should be washed that way, or with other singlets. Other fabrics (especially those with velcro or other fasteners) will damage the lycra fabric or can transfer lint to the singlet.
No Ironing - Hopefully this goes without saying, but don't ever think about ironing your singlet.
New Singlet Care
When washing your new singlets for the first time, wash each garment separately in cold water. This will maintain the maximum contrast between fabric colors and white fabric.
Do Not wash multiple new singlets together. Washing multiple new singlets together in one load, could result in loose dye release and staining of the uniforms
