clean the bristles and rollers. If your vacuum has become malodorous, try using a dryer sheet. For Roomba owners, iRobot has a number of helpful videos on their support site, such as step-by-step instructions for cleaning each model (check out this one for the Roomba 700 series).
2. Household Cleaning Appliances One might think that washers, dryers, and dishwashers clean themselves each time they run, but grime and debris can build up in these appliances over time. Your dishwasher may be cleaned with household standards such as baking soda, white vinegar, and an old toothbrush. Your laundry machines can be easily maintained as well, so no excuses! Lastly, be sure to regularly clean or replace the filters in your air purifier, HVAC system, or AC unit.
3. Computers & Devices As large desktop boxes lurch into the sunset, computer cleaning requirements are generally becoming simpler. You don't need to worry about dust accumulating in your iPad's massive cooling fans because it doesn't have any. These days, a good spray cleaner and microfiber cloth are your best allies. iKlear, maker of specialized gadget-cleaning materials, has some simple instructions for cleaning your microfiber cloth on their FAQ page. Remember, you can clean day in and day out, but your home will only be as clean as the tools you're using. Keep these essential appliances and accessories maintained to avoid costly repairs (and grimy discoveries)! (Images: 1. Kimberly Watson, 2. Flickr member Old Sarge licensed under Creative Commons, 3.
