(2) One part CPPC Ultra Bleach 2 (6.15 percent sodium hypochlorite; EPA Reg. No. 67619-8) in 3.1 parts water.

(b) Applying steam to all surfaces until the point of runoff, and so that a critical temperature of 170 °F is reached at the point of contact.

(c) Cleaning with a solution of hot water and detergent, applied under pressure of at least 30 pounds per square inch, at a minimum temperature of 170 °F.
