Find a couple canning jars at the thrift store in two different sizes that would work as hand soap dispensers for the bathroom and kitchen. Choose a basic glossy white spray paint and spray it on the outside of the jars. Then take a nail and hammer it into the center of the jars' lids to start a hole. Use needle nose pliers to pull the tin back enough to fit the soap dispens...
Keep the mess in the towel then throw the towel in the laundry when you get home from your trip.
The Duggars' Homemade Liquid Laundry Detergent - $0.01 / load....hmmm, lots of good reviews on this. Maybe I will try it. Maybe.
According to one pinner: Holy Cow!!! This stuff is AWESOME!!! I only made 1/2 as much (I didn't have as much lemonade as I thought, oops). I will not be buying dishwasher soap ever again!!!! My tupperware looks brand new again!
Another pinner said: The Duggars Homemade Liquid Laundry Detergent. Ive been using this recipe for a few months now and will never go back to buying Tide. This soap works as good, if not BETTER than Tide. The savings alone should be reason to try it out. Leaves no scent on clothes and they still come out soft. I love this stuff! (Rated 5 - TRY THIS STUFF! Its seriously amazing!)
