Frequently Asked Questions

What PSI is safe for cleaning small decks?

For most small decks (especially wood), we recommend 1500-2000 PSI. Higher pressure (2500+ PSI) can damage softer woods. All our recommended models include adjustable pressure settings.

How often should I power wash my deck?

Most small decks benefit from annual cleaning. High-traffic or shaded decks may need biannual cleaning to prevent mildew buildup.

Can these portable washers clean other areas?

Yes! These compact models work well for patio furniture, fences, sidewalks, and even vehicles when used with appropriate nozzles.
