??? Really ??? Punch a hole in the top of a bottle of vinegar and sit the bottle in your toilet tank. In doing this you will save water, as the tank wont fill as much, the vinegar will clean your toilet AND tank on each flush, it leaves the bathroom smelling fresh and it doesn't harm any component of your toilet OR the environment when flushed. And won't hurt the dogs when they drink out of the toilet like the blue stuff does.
Instead of using extra laundry detergent to pre-treat, we turn to our old school friend: white chalk. Simply rub onto greasy stains and the chalk powder will absorb the grease, making the stain easily removable by the laundry soap in the wash.
You can add a pinch of salt to your laundry to keep colors vibrant. It seems like every laundry detergent makes claims to keep colors lasting for a long time, but the easiest trick is to add a tablespoon of salt to the load. The premise is that the chloride in salt helps keeps clothes bright by sealing in the color across repeated washings. Salt also contains the power to remove bloodstains, but it turns out it's a great protector of clothes as well.
