I've been doing laundry by hand a lot recently, especially since I've acquired a few pieces of merino wool clothing that require it to extend the life of the garments.
I made some homemade laundry powder which is a combination of washing soda, baking soda, borax and some grated hand soap. Sometimes I throw a little citric acid or vinegar into the rinse water to neutralize the alkaline washing solution.
I also developed my own technique of squeeze drying clothes where I inch down a garment alternating hands as I squeeze down a line from top to bottom letting gravity help with the draining. I don't wring it in a twisty motion and put extra strain on the fabrics.
Since I've been doing a lot of traveling for the last 18 months, I've been using a dry bag with a window as both my hamper to keep out odors from my bag, and as my '
bucket' when washing.
I usually seal the bag and let it soak with the laundry powder for about an hour before I manually massage it for 5-10 minutes. I've gotten the hang of it, and I sort of enjoy the process.
