Cleaning and maintaining the outside of your home is just as important as the inside. It keeps your home’s exterior strong and durable while boosting your curb appeal. Traditional cleaning methods are effective, but there are some clever alternatives that can make the job easier and more efficient. This article explores four innovative ways to tackle common exterior cleaning challenges, from mildewed siding to rust on concrete.
Problem: Mildewed Siding

Mildew on siding is unsightly and can lead to long-term damage if left untreated. While pressure washing is a common solution, there’s a simpler and more accessible option for spot cleaning: the Mr. Clean Magic Eraser.
The Magic Eraser has gained popularity as a versatile cleaning tool, and it’s particularly effective at removing mildew from siding. The secret to its effectiveness lies in the melamine foam’s superfine abrasive texture, which works mold and mildew spots out of vinyl and wood siding without causing damage.
To use the Magic Eraser on your siding, follow these steps:
- Wet the eraser and squeeze out excess water.
- Gently rub the affected area in a circular motion.
- Rinse the cleaned area with water to remove any residue.
This method is ideal for small- to medium-sized mildew spots and can be a quick fix between more thorough cleanings. For larger areas or persistent mildew problems, the traditional pressure wash method is best.
Beyond removing mildew, the Mr. Clean Magic Eraser can also tackle other stubborn stains on siding, making it a multifunctional tool. It’s a convenient solution for homeowners looking to maintain their exterior without investing in heavy equipment. The Mr. Clean Magic Eraser is readily available and affordable. You can get a four-count pack at most home improvement stores.
For stubborn mildew that resists spot cleaning, consider specialized products designed for exterior use. KRUD KUTTER House Wash contains SPOREX, an additive that removes tough stains from mildew, mold, and algae without bleach — making it safe for surrounding plants and pets. One gallon of concentrate makes 20 gallons and can clean up to 4,000 square feet when applied with a pump sprayer or brush.
Problem: Dirty Windows

Clean windows can dramatically improve your home’s appearance and let in more natural light. However, cleaning exterior windows, especially on upper floors, can be challenging and potentially dangerous.
The Brillo Sweep and Mop is a great solution for cleaning hard-to-reach windows. This lightweight mop features a 360-degree swiveling head, a self-anchoring sponge, and an extendable handle, making it ideal for cleaning windows and floors.
To clean your windows with the Brillo Sweep and Mop, follow these steps:
- Fill a bucket with warm water and a mild detergent solution.
- Dip the mop head in the solution and wring out excess water.
- Use the mop to clean the window surface, starting from the top and working your way down.
- Rinse the mop head frequently to avoid streaking.
- Use a squeegee or microfiber cloth to remove excess water and achieve a streak-free finish.
This method allows you to clean second-story windows safely from the ground, eliminating the need for ladders in many cases. The extendable handle ensures you can reach high places while maintaining your balance on solid ground.
The flexibility of the Brillo Sweep and Mop makes it handy for cleaning other surfaces, such as patio doors and car windows. The Brillo Sweep and Mop starter kit is available at most grocery stores and online retailers.
Problem: Oily Driveway Stains

Oil stains on driveways are unsightly and can be slippery and dangerous. While there are many commercial driveway cleaners available, clay-based kitty litter can be surprisingly effective.
Clay-based kitty litter is highly absorbent and can effectively soak up fresh oil spills from asphalt and concrete surfaces. This method is useful for recent spills before they have a chance to set into the surface.
To use kitty litter for cleaning oily driveway stains, follow these steps:
- Spread a thick layer of clay-based kitty litter over the fresh oil spill.
- Gently press the litter into the stain with your feet or a board.
- Leave the litter in place for at least 24 hours to absorb the oil.
- Sweep up the used litter and dispose of it properly.
- Hose down the area to remove any remaining residue.
For older, set-in stains, you may need to repeat this process or use a degreaser in combination with the kitty litter method. Clay-based kitty litter is an eco-friendly and budget-conscious option. It also works well on garage floors and other concrete surfaces. Having a bag of kitty litter on hand can be useful for other spills and leaks around the home. Clay-based kitty litter is inexpensive and can be found at most grocery or pet supply stores.
For concrete driveways, This Old House experts recommend checking if there’s a sealer present before treating oil stains. Simply spray water on the surface — if it beads up rather than soaking in, you’ll need to use a degreaser first to break through the protective coating.
Pro Tip: According to This Old House Magazine’s exterior cleaning experts, “Superabsorbent clay helps soak up oily patches from asphalt. Spread litter over a fresh spill. Wait a day” before sweeping up.
Problem: Rust on Concrete

Rust stains on concrete can be stubborn. These stains often result when metal objects are left on a concrete surface for a long time, where they can get rained on or hit by sprinklers. While there are commercial rust removers available, a pool cleaning product can be an effective alternative.
Acid Magic, often sold for swimming pool maintenance, contains muriatic acid, which is effective at lifting rust stains from concrete. Use this product with caution because it’s a highly caustic chemical.
Here’s how to use Acid Magic for removing rust stains:
- Put on protective gloves and eye protection.
- Dilute 1 part Acid Magic in 4 parts water in a plastic bucket.
- Apply the diluted solution to the rust stain using a brush or sprayer.
- Allow the solution to sit on the stain for 5–10 minutes.
- Scrub the area with a stiff brush.
- Rinse thoroughly with water.
- Repeat if necessary for stubborn stains.
Always follow the manufacturer’s instructions and safety precautions when using Acid Magic or any similar product. Properly dispose of any runoff to avoid environmental impact. This product is available at most hardware and pool supply stores.
For stubborn rust stains that resist initial treatment, consider using a power washer after the acid application. However, always use a low-pressure nozzle and keep it moving away from you while wearing safety glasses, as even low pressure can cause injury.
Additional Tips for Outdoor Cleaning
Maintaining a clean home exterior goes beyond addressing individual problems. Regular upkeep ensures that your home remains attractive and that minor issues don’t escalate into significant damage. Here are some additional tips to keep your home looking its best:
- Address any issues promptly to prevent further damage or staining.
- Apply a protective sealant to concrete surfaces to prevent future staining.
- Clean gutters regularly to prevent water damage and mildew growth.
- Inspect and clean your home’s exterior at least once a year, preferably in spring.
- Use soft-bristled brushes or cloths when cleaning to avoid scratching surfaces.
When cleaning gutters, Tom Silva, This Old House contractor, recommends using aluminum or stainless-steel screws to secure loose downspouts. “The shorter the screws, the better,” he says. For tough gutter stains, try this proven formula: mix ½ cup clothes detergent and ⅔ cup trisodium phosphate with 1 gallon of water.
These proactive measures will help you maintain your home’s style and integrity. Regular inspections also allow you to catch and address problems early. By developing a routine, you can save time and effort in the long run.
Pro Tip: Norm Abram, This Old House master carpenter, advises: “Those openings look small, but that’s where water gets in and heat goes out. I clean out old caulk and fill them with 30-year acrylic.” Pay special attention to gaps where siding meets doors, windows, and trim during your annual inspection.
