How to Clean the Exterior of a House. Keeping your house exterior clean not only makes it look better, but it will help keep you aware of any problems that might otherwise go unnoticed.
Things You'll Need
- Muriatic Acid
- Trisodium Phosphate
- White Kerosene
- Clean Rags
- Garden Hoses And Attachments
- Liquid Bleach
- Scrub Brushes
- Wire Brushes
- Oxalic Acid
- Power Washers
Wash your house once or twice a year, depending on your area's air quality and the amount of dirt deposited by the rain.
Rent a power washer, which uses your garden hose to shoot a high-pressure jet of water. Work from top to bottom to keep the dirty water below the areas you have just cleaned.
Make up a solution of 1 tsp. trisodium phosphate dissolved in a gallon of water. Use this to clean siding, masonry, rock, wood, and painted surfaces.
Treat mildew with regular laundry bleach applied with a sponge. Dark or heavy stains might benefit from a good scrubbing with a wire brush and a solution of 1/4 cup muriatic acid in 2 1/2 cups of water.
Get rid of rust on hardware and window screens with a kerosene-soaked rag.
Bring out the beauty of naturally weathered wood with oxalic acid applied with a scrub brush (read the manufacturer's recommendations for dilution).
