Why Concrete Patios Get Dirty
Concrete is porous, which means it absorbs dirt, moisture, and stains. In shaded areas, that moisture can feed mold and algae. Over time, foot traffic and outdoor living leave the surface dull and patchy.
- Porous concrete absorbs dirt and grease
- Moisture in shade leads to mold and algae
- Foot traffic grinds dirt into the surface
- Grills and plants leave stains

Frequently Asked Questions
Can I pressure wash my patio myself?
Yes, but use a wide spray, keep the wand moving, and avoid older or damaged concrete. Pre-treating with a cleaner is often the real difference-maker.
How often should I clean concrete?
Sweep and rinse as needed. Deep clean once or twice a year, more often in shaded or humid areas where algae grows faster.
Why do stains keep coming back?
Moisture, shade, and poor drainage can cause algae and mildew to return. Treat the root cause (sprinklers, puddling) to keep patios cleaner longer.
