The treatment depends on whether the floor is carpet,or wood.
If wood,is it sealed?
Has the deposit been in contact with the sealing substance long enough to soften it? There may be no alternative to replacement a laminate.
Carpet wee stain should be flooded with a mild detergent solution eg baby bath in water. This should then be soaked up with repeated application of dry towel and pressure - typically, folding an old bath towel,placing it over the spill and standing on it.
Then pour clean water over the site,and repeat the blotting process.
