When we first got the new machines (Thankfully we ordered the set instead of just the replacement dryer, because moving the washer revealed a hidden leak. Yikes!), I wondered about my laundry detergent. I've been making my own detergent for over a year, and I LOVE it. So simple and cheap, and I get to add the essential oils I like to the mix. Love, love, love. But, I wondered about using it in a high efficiency washer. It turns out the homemade stuff should actually be better than the commercial detergent for the machine, because the homemade detergent is naturally low-sudsing.
You can find several laundry detergent recipes to try at Tipnut. I always preferred the liquid detergent, so I adjusted the recipes to make a smaller batch for myself, enough to fit into two large, recycled detergent bottles. I put a little lavender oil in it to keep it from getting funky and smell nice, and sometimes I add a little extra lavender for sheets, peppermint oil for pet bedding, and lemongrass oil for towels. Just my preferences (and the peppermint is a nice bug repellent).
Now I'm considering switching to powdered recipe #4 on that site. I have used it in the past (I keep a small batch of those ratios for traveling), and I think it would be so much easier to grate the soap, toss it in the food processor, then mix it with the washing soda, borax, and essential oils. In the past I had trouble with the powders dissolving properly, but I think the new washer will do a better job with that.
Anyone else love homemade laundry detergent as much as I do?
