4. Don’t overload your washer.
Give your clothes plenty of room to move! If they’re too packed in, they won’t be able to circulate and get clean. I know I have a tendency to want to fit more in, so I can get more laundry done, but in the end, it doesn’t save me any time.
5. Use a lower heat setting on your dryer.
Higher heats have the potential to scorch or singe your clothes, making them more yellow. Also, only keep them in the dryer as long as they need to be, and take them out as soon as they are dry.
6. Use bleach when appropriate.
I like to use bleach. It gets rid of stains that I just can’t get out any other way. That said, you do have to be careful. There are some fabrics that shouldn’t be bleached, and even some white cotton towels will have a “No Bleach” warning on the label. It’s most likely due to a some kind of finish that’s on the towel that isn’t appropriate for bleach. When using bleach, it’s best with hot water—the hottest possible—so keep that in mind when checking care labels on your clothing and white items.
DO NOT MIX BLEACH WITH ANYTHING ELSE! It does not mix with vinegar or peroxide, and should only be used on its own (except your laundry detergent). Always do your research and read the directions on the bottle before acting.
