What Causes Hard Water Buildup On The Exterior

What Pressure Washing Can Clean, And What It Cannot

The first job is to tell the difference between removable buildup and actual damage.

On smooth surfaces, such as painted siding, metal panels, and some sealed masonry, the stain often breaks down with a combination of detergent, dwell time, and low to moderate pressure.

Glass is more delicate. If mineral buildup has sat too long, the stain can bond tightly enough that pressure alone will not clear it.

• brick, stone, and stucco near irrigation overspray
• fences, railings, and metal fixtures exposed to overspray
• driveway edges and hardscape where water dries again and again

For example, glass can go from cloudy to clear if the mineral film is still on the surface, but etched glass may keep a ghosted look even after cleaning.

Clean mineral lines make the whole property look better maintained, even when the improvement is small and specific.

Preventing Repeated Mineral Buildup Around The Home
