In my home we have a huge issue with keeping our white clothes white, they always begin looking faded or greyish after only a few washes. Because we don`t have any extra money laying around to take care of that pesky problem we use some household items that did wonders!
Most commonly used to whiten clothes. Fill your machine with the clothes and hot water, and then add LOTS of lemon slices for about an hour or two (if you can let them sit over night) then you wash as you normally would. Your clothing will be fresh and clean with a nice smell of lemon on them.
You can add white vinegar too your clothes to make them brighten up. The vinegar also cleans up any left over residue from the other soaps and thus makes the clothes softer. Simply add about one cup into your white clothes along with the regular laundry detergent and let it run like normal. It may smell like the vinegar when you go to move the clothes to the dryer but after they have been thoroughly dried they will not smell like it at all.
Baking soda works well in the laundry machine by deodorizing and cleaning the clothes and also whitening at the same time. Simply add the baking soda to your normal laundry cycle and your clothes will look and smell great. You can also add baking soda in with lemon juice to make a whitening mixture.
The whiting agents in the dishwasher soap will work away on the stains on your white clothing and clean/brighten them right up. Add about ¼ cup of the dishwasher detergent to warm water with your clothing and your regular detergent. Everything will look and smell great when you are done.
Hanging your clothes out to dry may not be an option where you live but if it is, then go ahead and try it out. It may not be the most powerful way to whiten your clothes, but it does not hurt to try.
