Give this a try. It is great as a clarifying shampoo! It will remove all residue and product build up form your hair but be careful using it on coloured hair as it is a natural hair lightener. It will leave it feeling really clean and with more body! Great for blonde hair with product build up.
How to clean your garbage disposal. Start by running hot water through your garbage disposal for a minute. Pour about 1/4 c. baking soda into the drain. Flip the garbage disposal on for 2 seconds, just to whirl the baking soda inside, and then leave it alone for 10-15 minutes. Follow with 1 c. of vinegar. Watch the bubbles erupt out of your drain. (Yay!) Rinse through one last time with very hot water and run your garbage disposal for 5 seconds.
