Laundry stripping is a method of washing that removes odors and buildup of detergents, minerals, body oils, and fabric softeners. It's easy, effective, and only needs to be done once in a while.
Gather the clean laundry that you want to strip. It can be either wet or dry, but it should be clean. Before strip-washing, I washed my towels on my washer's sanitize function with extra hot water. I recommend washing your laundry first in the hottest water your fabrics can tolerate.
Fill a bathtub, top-loading washing machine, or large bucket with HOT water.
Pour 1/4 cup of washing soda, 1/4 cup of Borax, and 1/2 cup of powdered detergent into the hot water. The recipe is a 1:1:2 ratio, so you can adjust the measurements if you have a smaller or larger basin. For a regular-sized bathtub filled 1/2 way, the measurements listed in this recipe are appropriate.
Use a large spoon to swish the water around (the cleaning solution can be harsh on your skin). Once the ingredients have dissolved, toss them into your laundry.
Allow the laundry to soak for about 4-5 hours until the water has cooled to room temperature. Use the spoon to agitate the laundry about once an hour or so.
Enjoy the satisfaction of seeing the water becoming a murky mess.
Drain the tub and wring out the fabrics. Try to get out as much water as possible.
Wash your laundry without detergent in the washing machine (hot water is preferable). Dry as usual.
Snuggle up with your fresh duds!
Notes
The cleaning solution can strip the dye out of your fabrics. With that in mind, I would not strip anything delicate or sentimental. Additionally, dark fabrics can not only fade, but they could bleed onto lighter color items.
