Dirty siding makes a whole house look older than it is. In North Texas, the usual culprits are pollen, dust, red clay splash, and green or black mildew on shaded walls. The right way to clean siding depends on what it is made of.
The Short Answer
For most siding, the safest method is a low-pressure soft wash: wet nearby plants, apply a siding-safe cleaning solution from the bottom up, let it dwell, and rinse gently from the top down. Avoid high pressure on vinyl, stucco, painted wood, and older brick mortar.
Siding Cleaning at a Glance
| Siding type | Best method | Watch out for |
|---|---|---|
| Vinyl | Soft wash | Forcing water behind panels |
| Brick | Soft wash, low-pressure rinse | Eroding mortar joints |
| Stucco | Soft wash only | Chipping and wand marks |
| Painted wood | Soft wash | Peeling paint, raised grain |
| Fiber cement | Soft wash | Damaging the painted finish |
How to Clean Vinyl Siding
Vinyl cleans up easily with a soft wash. High pressure can drive water behind the panels and into the wall. See how to clean vinyl siding and, for faded panels, chalky vinyl siding.
How to Clean Brick Siding
Brick handles more than vinyl, but mortar is the weak point. Use a cleaning solution and low-pressure rinse. See how to clean brick and efflorescence on brick.
How to Clean Stucco
Stucco is porous and easy to damage, so it should only be soft washed. See how to clean stucco.
How to Clean Wood and Fiber Cement Siding
Painted surfaces need gentle cleaning. High pressure can lift paint and raise wood grain. Soft wash, rinse well, and check for peeling paint afterward.
Removing Mildew and Algae
Green or black patches on north-facing or shaded walls are growth, not dirt. Scrubbing or pressure alone rarely removes it at the root. A cleaning solution that kills mildew and algae does. See how to soft wash a house.
