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.
The "miracle" of baking soda and peroxide. Put 1/4 cup of baking soda in a bowl.....add enough peroxide to make a paste. Rub on with fingers or sponge. Cleans EVERYTHING! Stove, oven, pans, stainless steel applicances, even the white handles of the refrig door<---for when I burn the pan after steaming broccolli!
Shower Cleaner 1/2 Dawn and 1/2 Vinegar in a dish wand. Clean after every shower. MY REVIEW: nothing got rid of the mildew like this combination. Know that only dawn works - it supposedly has an ingredient that others don't. The wand was a great idea too because let's face it, the most dreaded chore next to cleaning the toilet is cleaning the shower.
