Urine should be cleaned up using the Water Based Stains Cleaning Method.
Tools & chemicals:
Neutral pH low residue spotter, terry towels, water.
Using a terry towel, soak or blot as much of the urine as possible. If the stain is fresh most of the urine can be soaked up this way. Be sure you have lots of towels and always use a completly dry area of the towel to blot with.
Now using a neutral pH low residue spotter, apply a small amount, blot and repeat until the stain is removed.
An alternative is to mix 1 tsp. of neutral pH liquid detergent (dish washing or fine fabric detergent that does not contain any bleach ) into 1 cup of warm water. Tamp, do not scrub as this may distort the texture of of the pile. Cover with a white terry towel and press down repeatedly.
If the spot or stain turns brownish when dry, mix 1:2 white vinegar and water. Apply a small amount and blot. Repeat only once.
