Does the soapstone come already treated with the mineral oil?
No. This is done after the countertops are completely installed. The oil is applied easily with a cloth, allowed to soak in, and then the excess is wiped off. This process is repeated, approx. twice a week for the first 3 months or so, then once a week for another 3 months or so, then once a month for about six months. Thereafter, apply as needed (when colour lightens). Mineral oil is readily and cheaply available at drug stores.
