★ Put some DAWN in your Shower ★
If you coupon, chances are you have a GOOD stockpile of Dawn Dish Detergent since this coupon usually comes out Monthly in the P&G Inserts!
You can usually grab the little bottles (9 oz.) at CVS with a sale anywhere between $0.25 and $0.50. Once you have used most of the detergent washing your dishes, DO NOT THROW that bottle out! Fill it up with some hot water and shake well, and put it in your shower. Every few days when you are in the shower, squirt some around on the walls and wipe them down. It work GREAT, Smells delightful, and keeps you from having to use those caustic shower cleaners!
