Well, I decided to finally try Thieves® Household Cleaner in the washing machine.
I've had sickness in the house since right after Christmas (why can't the kids all get sick at once?), so I wanted to give blankets, sheets, towels, and comforters an extra dose of disinfecting!
I added about 1 capful to a large load. And It worked great. I worried about discoloration for nothing, but I'm not exactly ready to use it with my clothes. :)
My house sure does smell good when my kids are sick! Thieves® everywhere - in our mouths, in the air, in the laundry - you name it! I think it is safe to say that sickness is finally at bay. Whew!
