WARNING: Ammonia is not widely recommended as a cleaner for wood flooring because it has a very acidic pH that can eat into and lead to dulling of the floor finish or even bleaching of the surface. Ammonia is really not suited for this purpose; there are dozens of better options that clean and protect your flooring.
However, if you still want to use ammonia, here's how...
Dilute the ammonia. When using ammonia, it must be in an extremely diluted form -- no more than 1 or 2 teaspoons in 2 gallons of tepid water. Apply with a well wrung mop and rinse floor well with pure water. Better options follow below.
