These mix together really quick and I learned through experience that you need to be sure they are wet enough to form or they fall apart. Also, to keep them from sticking to your hands, I have found wet hands makes it so much easier. If you have sensitive skin, you might want to wear disposable gloves when forming the tablets. When forming your first tablet, be sure it fits into the dispenser of your dishwasher. Flat rectangles work for mine, but every machine is different!
1. Mix dry ingredients together in a medium sized bowl. Add the lemon juice and mix completely. You want the mixture to be wet enough to mold without falling apart. Add additional lemon juice if needed.
2. These dry very quickly so working quickly and one at a time, portion out a tablet around 2 tablespoons. I used a small cookie scoop. With wet hands, form the tablet into whatever shape needed to fit the soap dispenser in your dishwasher. Place on a sheet of wax paper and let dry for a few hours before putting in a storage container. If a tablet happens not to fit into the dispenser, just toss it in the bottom of your dishwasher.
