Simply take an empty foaming soap dispenser & your dish soap. (The same method can be used to make hand soap, just replace the dish soap with hand soap.)
Fill 1/4 of the pump with soap & fill the remainder with water. Gently mix together.
Voila, you have foaming dish soap! Just add a few pumps to a sink of dishes & you're good to go. Look forward to long lasting bottles of dish soap & fewer trips to the store!
