Patio Cover Cleaning in San Dimas & SoCal
Low-pressure patio cover cleaning that removes dirt, buildup, tiger striping and environmental grime from aluminum and other patio covers.
Get Rid of the Streaks
Patio covers collect dust, leaves, bird droppings and the dark vertical streaks called tiger striping. High pressure can damage the coating, so we clean them gently.
We pre-soak the cover, apply a cleaner that is safe for the surface, agitate problem areas by hand, and rinse at low pressure.
- Gentle pre-soak
- Surface-compatible cleaner
- Soft agitation of problem areas
- Low-pressure rinse

How It Works
1. Look it over
We check the cover material, coating and any loose or damaged sections.
2. Pre-soak and treat
The cover is soaked and treated with a cleaner made for the surface.
3. Agitate
Tiger stripes and heavy spots are worked by hand.
4. Low-pressure rinse
We rinse it clean and clean up underneath.
Good to Know Before We Start
We put this in writing on every estimate so there are no surprises.
- Faded coatings, chalking and permanent staining may remain after cleaning.
- Oxidation restoration, repainting, structural repair, rust repair and replacement are not included unless quoted.
- Loose paint, leaks or damaged components are not caused by cleaning and are not covered.

Patio Cover Cleaning FAQ

Do you clean the patio underneath too?
Yes, if you add it. Patio and concrete cleaning are often done in the same visit.
