How do you clean?
Question:Help- we just had a new deck put on our house, pressure treated wood, and our male shih tzu is constantly peeing on it, now we notice a dark stain. is there something we could use to clean it off, and not ruin the finish of the wood or dull the look of the deck? Help please, my hubby is not happy with our Murphy----
thanks to all who can help
Answers:
If the finish on the deck is not keeping it from staining, then it is a penetrating type finish and anything that will remove the "stain" will also remove your stain (your finish), or at least dull it a bit. You will need to use the same product to fill back in, or maybe even clean the whole deck and start over.
The "stain" should come off with a solution of bleach and TSP. Gallon of water, quart of bleach, 1/2 cup TSP. Brush on, scrub a bit with a medium bristle brush. Let is soak for 20 minutes or so. Rinse with plenty of clear water.
If for some reason that solution does not work, a product called oxalic acid (also called "wood bleach") will. A good home center will have it. Follow the directions on the box -- although I like to mix it a bit stronger than what it says.
You are definately going to have to sand the area. You can then apply matching stain to the same area as which can have a protector in it. A Water seal would be great to apply. But you might want to teach rover there that peeing where he pleases is not appropriate.
You can't sand pressure treated wood. It will release toxic dust into the air. This is a tough question to answer, but quite frankly if your husband is going to get upset with spots on the deck he should never have constructed it from wood. In a year it will be spotted everywhere.
In the meantime, however, I would try a pet stain remover from the pet supply store. I personally use Simple Solution. Pour it on the spot, and I mean pour so that it is soaked. Let is soak in and dry out. I did this w/ cat issues on wood subfloor and it was amazing. After 24 hours you couldn't even tell there was a stain. Don't know about pressure treated, but it's worth a try.
