urine stain in unfinished Oak table

Hey guys, I am building a custom oak entertainment center for my wife and we also got my son 3 miniature goats. We kept the goats in the garage during our brutal cold weather and unfortunately a goat urinated on the table top.

The top had been stained, but not polyurethaned yet. So the urine stain seeped in a little bit. Can this be saved?

Veneer or solid? Red or white oak? Can you post a picture of the damage?

More than likely you can wash the table with a mild detergent, rinse and allow it to dry, then sand the rest of it out. It all depends on just how bad they got it.

Steve, I agree with what you are saying and you may very well be right.


My concern is how deeply the urine soaked in and if there was any chemical reaction especially with the high tannins in oak and neutralizing the remnants of the urine. The thickness of the veneer will also play a part as to how much sanding can be done without sand thru. Of course red oak with its large pores will wick up more urine and likely penetrate the full depth of the veneer, if it is veneer.


This message is for the OP and other viewers who may not have much experience with this, or similar issues that arise while working with wood and preparing for a finish.

It is red oak and the first stain is on the solid oak 1" thick top... the 2nd stain is on the oak plywood bottom. I will post pictures in the morning.

Without pictures we can't begin to guess how many time they got it. If it was just one or two times it shouldn't be a problem even if it's veneered. If it was multiple times over months where the wood is turning black then that could be a real problem even if solid wood. Then it would take two part wood bleach to clear up. Then bleached it's going to be difficult to make look normal again so there really isn't a good fix if the damage is severe.

How much experience do you have with goats peeing on your projects?

I have an Industrial Technology degree, teaching experience, and time in the trades. Goat urine would be new to me, however urine stains and hardwood floors are not. Tannins especially in oak will react with the uric acid turning the wood black. Fun fact, urine is sterile and may save your life as a replacement for water when there is none. Not recommended to be repeated as the concentrations of chemicals become high. No, I've never had the need to partake and goat urine would be at the bottom of the list.


The reason for the statement that you quoted was out of respect to Steve and his experience, but your comment did make me laugh. Guess I set myself up for that one!

Oxalic acid will help with the stain. Fresh air and sun exposure may help with the smell. BBQ goat is kinda stringy but not too bad,

Oh good, for a second there I was worried you'd taken me seriously.

I really think if the goat had much access to the table he would have ate it.
