Washing Hardie Plank Siding

In response to our recent inquiry, James Hardie, manufacturer of Hardie Plank siding, has updated their guidelines for properly cleaning their siding products.  Here is an excerpt from their recent communication with Sparkle Wash HQ.

Note: If a pressure washer is to be used, use wide fan tips only, at low pressures under 1,500 psi and at safe distances. Keep fan nozzle no closer than 6’ to wall. Exercise extreme caution. Improper use could lead to damage of the surface and in-turn, a loss of warranty coverage.

Sparkle Wash standard operating wash practices for this surface fall within these parameters.

Happy Sparkle Washing!
