I just made up my second batch of homemade laundry soap. I switched over to homemade soap back in June. Over all I am happy with the switch. It has definitely saved us money. The soap I made in June lasted a little over 3 months, and trust me, we do A LOT of laundry at our house. Here are a few things that I have observed.
Clothes that are washed must be removed from the washer within 12 hours or so or they will start to develop a stink. When I used commercial laundry soap I could let the clothes sit in the washer a day or so and there was no odor. The perfume used in the soap would make the clothes still smell nice when I finally took them out.
Things that are heavily smelly (like son's football gear) still smell after washing with the homemade detergent alone. I have been adding vinegar to the water but I still get a funk. So, I have reserved commercial detergent for those kind of items. Any suggestions on that?
Like I said over all I am happy with the switch and will continue to use homemade laundry soap. If you are interested in the recipe you can read my post here.
