I started doing this and will never stop! My tub shower are always spotless-so simple. Simple shower and tub cleaner: fill wand half and half. Wet surface and scrub. wow! leave in shower wash while you are already in there - THIS REALLY WORKS!!!!!!!!!
You put about 1/4 cup of baking soda in a small glass bowl and squirt in hydrogen peroxide until it makes a nice paste. Then you rub it on the offending dirt/stain/grease. Use fingers or a small sponge.
Another pinner says: I just did this to my sink and it looks just as shiny as the picture. I didn't think my old, nicked up, stainless sink could look so good, but it does! How to make your stainless shine.
Best grout cleaner out there and its for carpet! Resolve carpet foam. Spray it on. Leave for 10 min. Scrub it off with a stiff scrub brush! Wha la!! :)) Tip:as you scrub wipe the dirt that comes up off. If you don't it will just soak back in before you get back to mop it off.
