How to Clean Blood Stains Off a Wooden Deck

Most wooden decks are made from finished wood, so cleaning blood stains requires little more than a quick swipe with a wet, soapy sponge or rag. With quick action, the stain won't have time to penetrate through layers of finish.

Bloody Stains

  1. Dab--don't rub--the stain with a clean sponge or rag soaked in cold water and lathered with regular dish soap.

  2. Use ammonia for a particularly stubborn stain. Dab a little bit onto a fresh rag or sponge, dilute with cold water, and then dab onto the stain.

  3. Repeat as necessary.

  4. In extreme cases, you might have to sand down the stained area and refinish it.
