Is this ready to use or does it need mixing?

It is a concentrate. Dilute it with water as the label directs, or add it to a carpet cleaning machine's tank. It is not meant to be sprayed straight from the bottle.

Can it be used in a carpet shampooer?

Yes. The liquid is designed for dilution and machine cleaning of carpets. Follow the machine maker's mixing ratio so you don't over-suds the tank.

Does it work on pet urine odor?

It is made for pet accidents, including urine. Fresh accidents clean up best; old, soaked-in stains and odor often need more than one pass.

Can I use it on upholstery and rugs?

It is labeled for textiles, so it suits carpet and upholstery. Test a hidden spot first, since some fabrics and wool rugs can be sensitive to cleaners.

How much area does the 60 oz bottle cover?

Coverage depends on dilution and your machine. Because it is concentrated, one bottle makes several tanks of cleaning solution, far more than a ready-to-use spray.
