After a harsh winter and an unpredictable spring, your home and garden may need some attention. But before grabbing that pressure washer, think again. While these machines are great for certain tasks, they can cause more harm than good when misused.
Pressure washers excel at tackling tough jobs, like restoring backyard pavers, but some surfaces should remain untouched. Cleaning them with a pressure washer can lead to damage, expensive repairs, or even personal injury.
A pressure washer, like the Kärcher K1700, utilizes a high-pressure water jet to blast away dirt, moss, and grime from hard surfaces. They work wonders on patios, decks, and driveways, especially if you're sprucing up your outdoor space this season.
7 Surfaces You Should Never Clean with a Pressure Washer
Here are seven surfaces to avoid cleaning with a pressure washer, along with safer cleaning alternatives.
1. Windows
Window cleaning can be incredibly satisfying, but using a pressure washer is a bad idea. The powerful jet can shatter fragile glass or damage double-paned windows, risking exposure to mold and moisture. Instead, opt for a vinegar solution or dish soap mixed with water and a squeegee. A highly-rated microfiber squeegee from Amazon can help, or use microfiber cloths for interior windows.
For rinsing, a simple garden hose with a nozzle attachment will do the trick.
2. Bikes and Cars
If you're aiming for a spotless vehicle, you might consider a pressure washer, but beware of potential damage. While some washers claim to be safe for bikes and cars, high pressure can strip paint, create dents, and even lead to rust. For cleaning, hand washing with a soft sponge is best; consider using a microfiber wash pad from Amazon. If using a pressure washer, maintain at least six inches from the paint and a foot from damaged areas.
3. Render Planters
Rendered planters and raised beds are beautiful additions to your garden, but they require care. A pressure washer can damage the render, potentially causing it to separate from the structure.
4. Wooden Garden Furniture
To keep your outdoor wooden furniture looking great, avoid pressure washing, as it can lead to splitting and chipping. It may also strip any waterproof sealants you've applied, exposing wood to the elements. Instead, clean gently with a soft cloth and the grain. There are specialized cleaners for certain woods, like teak, that can restore color and protect against stains. Check out Star Brite's Teak Care Kit at Walmart for added protection.
5. Light Fixtures
Outdoor lighting can accumulate dirt over time. However, using a pressure washer can damage the fixture and potentially allow water to enter electrical components. To clean, remove the bulb and wipe the fixture with a damp microfiber cloth, like these microfiber cloths from Amazon. Use an old brush to clear away debris first.
6. Asphalt Shingle Roofs
While cleaning your roof might not be a priority, moss and dirt can cause significant damage. Avoid using a pressure washer on asphalt shingles, as it can loosen tiles, especially on older roofs, leading to leaks and structural issues. If your roof needs cleaning, hiring professionals is the safest route.
7. Pools
As summer approaches, pool maintenance is vital. While you may want to use a pressure washer to tackle algae, it's risky. Excess pressure can damage the pool's surface and lead to leaks. Instead, focus on chemical treatments or consider a robotic cleaner, like this cordless robotic cleaner from Amazon.
What Can You Clean with a Pressure Washer?
When used correctly, a pressure washer can be incredibly useful. Before you buy one, consider what tasks you'll use it for. There are basic models with fixed nozzles, or more advanced ones with adjustable settings, rotating brushes, and specialized kits.
Here are some items suitable for pressure washing:
- Concrete patios and pathways
- Driveways
