After surveying dozens of people who have spent their professional lives cleaning kitchens and bathrooms in London, here are the five most surprising cleaning facts they came up with. You should feel very honored.

Amazing Cleaning Fact #1: Your kitchen is the dirtiest room in your house – positively gross. London cleaning professionals know that as long as you flush regularly, your sink will be dirtier than your toilet. More seriously, bacteria left over from food preparation and disposal accumulate throughout your kitchen. Invest in an industrial strength antibacterial cooking spray. Don’t just spray and wipe, as these products take time to do their job. Spray the spray and then watch TV for a while. Come back in twenty to twenty-five minutes and give the surfaces a good scrub before wiping them down with a clean cloth. If a clean cloth is not used, it defeats the purpose entirely.

Amazing Cleaning Fact #2: Your sofa is a breeding ground for dust mites, particles, and microscopic samples that cause allergies. A professional sofa cleaning or a dedicated afternoon vacuuming session is required to get rid of these. The Victorian hit of household furniture with an outdoor broom handle comes in handy here, too. Imagine all those stray hairs and little bits of dead skin coming out of your house. The thought is positively uplifting.

Amazing Cleaning Fact #3: Most adults spend more than 8 hours a week cleaning homes and offices in London. If you have children, this figure could triple or even quadruple. Be efficient with your cleaning efforts and don’t waste time. You might even find time to take a second job or spend an extra night a week at the pub.

Amazing Cleaning Fact #4: Club soda is great for cleaning emergencies. Forget the old wives’ tales about white wine removing red wine stains unless you want a larger stain made up of red and white wine. Apply carbonated water to clean sofas or on your clothes or rugs and gently blot away moisture and stain with a dry cloth.

Amazing Cleaning Fact #5 – The Grand Finale: The Dirt Comes From The Outside! Keep the pavement and driveways clean and you may notice a miraculous change in the cleanliness of the house.
