Comet Cleanser with Bleach is one product that I always have in my home. I pay just over one dollar for a 21 oz can of this powdery cleanser, and it is well worth the money I spend.
The way this product works is very simple, you simply wet the surface you wish to clean, sprinkle on the Comet and scrub. I use this prodcut in my bathroom as well as my kitchen and it always leaves my tub and sinks clean and shining. You know those pesky black marks that are often left behind in a white porcelin sink? Comet takes those right off. Soap scum and hard water stains are also easily removed with this product.
The scent is light and pleasant, and for those who want a little extra scent, the product is also offerred in a lavander scent. Personally, I prefer the regular scent; it is not too strong, but definately smells clean.
Overall, with its many uses, I would highly recommend Comet Cleanser with Bleach for absolutely every household.
