Baking soda neutralizes the ph in the soil and nothing will grow there. use baking soda around all of the edges of flower beds to keep the grass and weeds from growing into beds. Just sprinkle it onto the soil so that it covers it lightly. Do this twice a year - spring and fall.
Your bathtub will never be whiter!! Works great on glass shower doors too- no more soap residue! Martha Stewart's Tub Scrub--works better than any other cleaning product to get off hard water and soap residue
The appliance repairman told me using the self-cleaning feature takes years off the life of an oven. The best oven cleaner! Cover bottom of oven with baking soda, then pour vinegar so it's all wet. Let sit around 20 minutes or so then wipe all of it out with damp cloth or sponge. I leave my oven door open too. After drying you may see some white residue, wipe again.
