If you don’t plan on washing the entire shirt, rinse the stain removal product off under cold running water.

You can also try adding some all-fabric bleach to your laundry cycle. This may take out stubborn stains if you don’t have a gel pen.

Oxygenated bleach is useful for brightening shirts that look dull. It’s used the same way as non-chlorine bleach.

Your best chances of removing unwanted dye is right when you notice the stain. Once the dye dries, removing it is unlikely. You may also be able to remove dye stains on your own with rubbing alcohol or bleach.

Most wear and tear from machine drying won’t show up right away. The polo may shrink at first, but the heat also can wear out the fabric over time. Instead of machine drying the polo now, you can also choose to throw the polo into the dryer for the last 2 or 3 minutes of the drying process.

If the polo is completely dry, you won’t have to worry about water damage. However, still try to put the shirt away as soon as you can.

Direct sunlight weakens and discolors fabric over time, so avoid drying your polos in it. You can also spread the polo on a drying rack instead of a towel.

A polo that has been partially dried in a drying machine may finish drying in about 15 to 25 minutes, although this varies depending on your environment. If the shirt seems to be drying slowly, try flipping it after 15 minutes. This encourages both sides of the shirt to dry at an even rate.
