Removing Urine Stains and Odors on Natural Stone
Removing Urine Stains and Odors from Stone
Urine accidents on natural stone in homes or businesses can cause staining and odor problems. Maybe your new puppy made a mess on your marble floor. Perhaps in front of the urinals in a business restroom the granite is stained and smells of urine. Whether it’s your puppy, poor aim, or some other cause, there are ways to remove these stains and odors. Here are some instructions for urine stain removal, and if odors linger after stain removal, we’ve also included instructions for urine odor removal.
The Chemistry of Urine
Urine is unique in that it is a substance that comes out of the body as an acid, and when it starts to dry, it becomes an alkaline crystal, which absorbs moisture. In the case of urine accidents, stains can grow as these crystals absorb moisture. If the stone is a polished marble or limestone, it can become etched due to the initial acid reaction, but it can also be etched from the strong alkali. If this is the case, the stone may need to be repolished.
Removing Natural Stone Urine Stains
Removing urine stains can be tricky and timing is everything. The quicker you can get to the stain the easier it will be to remove.
As soon as you can, blot the urine up with some dry paper towels. Do not wipe, since this will only spread the stain. Clean the stain with some dish soap and water. Mix about one teaspoon of dish soap in a gallon of water. Apply this solution to the wet area and allow it to sit for a minute or two. Blot the solution up and rinse with clean water. If there is still a stain, then you will need to apply a poultice.
Poultice To Remove Urine Stain
A poultice is a mixture you will create and apply to break down and draw out the stain from the pores of the stone.

Removing Natural Stone Urine Odors
Once the stain is removed, the urine smell may still be present. The nasty smell you may experience is the result of bacteria using the urine as a food source. So, to eliminate the odor, you need to kill the bacteria. Here is how to neutralize the odor:
There are numerous products on the market designed for eliminating carpet odors. These same products can be used for stone. Make sure the product is enzymatic. Many products will only mask the odor. Since you want to eliminate the odor, an enzymatic product is necessary.

The above processes are time-consuming but will be well worth the effort if done properly.
Urine Etch Damage on Natural Stone
It is possible in the case of polished marble or limestone that discoloration may persist despite your stain removal procedures. If the stone looks dull or has texture when you run your finger across the surface, then etching may have occurred. Sometimes, minor etch damage on stone with a polished finish can be removed using a marble polishing compound. For other finishes or deep etch damage, professional honing and polishing will be necessary. Your stone and tile restoration technician, who has the expertise to deal with this problem and can determine what needs to be done in your particular situation.
