# §761.375. Specific requirements for surfaces coated or covered with dust, dirt, grime, grease, or another absorbent material.

- (a) **First wash.** Cover the entire surface with concentrated or industrial strength detergent or non-ionic surfactant solution. Contain and collect all cleaning solutions for proper disposal. Scrub rough surfaces with a scrub brush or scrubbing pad, adding cleaning solution such that the surface is always very wet, such that each 900 cm 2 (1 square foot) is washed for 1 minute. Wipe smooth surfaces with a cleaning solution-soaked disposable absorbent pad such that each 900 cm 2 (1 square foot) is wiped for 1 minute. Wash any surface <1 square foot for 1 minute. Mop up or absorb the residual cleaner solution and suds with a clean, disposable, absorbent pad until the surface appears dry. This cleaning should remove any residual dirt, dust, grime, or other absorbent materials left on the surface during the first wash.
- (b) **First rinse.** Rinse off the wash solution with 1 gallon of clean water per square foot and capture the rinse water. Mop up the wet surface with a clean, disposable, absorbent pad until the surface appears dry.
- (c) **Second wash.** Follow the procedure in [§ 761.372(a)](/cfr/40/761.372.md?p=a).
- (d) **Second rinse.** Follow the procedure in [§ 761.372(b)](/cfr/40/761.372.md?p=b).
