Sometimes you just cant find the right tool for the job, even with all the usual cleaning tools at your disposal. Here are some tips for those items and places that are always a pain to keep squeaky clean.
The microwave - The solution for a clean microwave is in your refrigerator (or maybe in the produce section of the grocery store). Microwave a cup of water and a few lemon slices, and then use a sponge to clean the microwave with the warm water.
Grease stains - This one works on clothes as well as surfaces. Rub white chalk on the grease stain, let it sit for five minutes, and then wipe it away with a wet rag.
The television - Screens on HDTVs are delicate, and you want to avoid liquid cleaners, especially on LCD screens. Instead, take a dryer sheet and use it to clean the screen. The sheet will pick up dust and reduce static, and wont damage the TV.
AIR VENTS - Its always tough to thoroughly clean air vents because the spaces are so small, but they attract a ton of dust. Wrap a small towel around a butter knife, and then use the knife to clean the openings in the vent.
