Hardwater Stains On Wood Siding

The sun and water beat down on a deck snow can pile up.

Hardwater stains on wood siding.

Spray the water stain or stains directly and allow the vinegar to penetrate the scale. The best stains should last three to five years on a deck and even longer if applied to siding or fences which don t get as much abuse. Vinyl siding is susceptible to stains just like any other housing material. Wait about 10 to 15 minutes before proceeding as the hard water scale will take some time to soften.

Whether it is used for house siding outdoor furniture decks fences or sheds wood holds up well against weathering as long as it is maintained but whenever water and wood mix there is the possibility of water stains. Hard water stains are ugly but not impossible to remove. Stain generally comes in a variety of different pigment concentrations thus some will cover more than others. I tried soap.

We have very high iron well water at our house. On the other hand stain or dye will penetrate most materials including wood brick and sometimes even vinyl. Inexpensive distilled white vinegar available in half or whole gallons at your grocery store is acidic enough to break down the hard water spots yet mild enough not to hurt the siding. After some watering of the lawn we had some very heavy iron stains on the white vinyl siding.
