  • Mix MB-2 Alkaline HD in the following proportions with hot water:
    • Light soiling: 3 ounces to 1 gallon of water
    • Medium soiling: 6 ounces to 1 gallon of water
    • Heavy soiling: 8 ounces to 1 gallon of water
    • Stronger solutions can be used for extremely soiled conditions
  • For routine cleaning, use MB-1 Floor Amore for floors or MB-5 Stone & More for other hard surfaces.
  • Always test product in an inconspicuous area.


  1. Remove all loose debris from the surface to be cleaned.
  2. Strip the floor from wax or any topical sealers.
  3. Apply the diluted solution liberally with a mop or a sprayer and allow the product to dwell. For small areas, use a cotton rag or sponge.
  4. The level of soiling will determine dwell time. Light soiling may require a very limited dwelling time, a few minutes. The longer the product is allowed to dwell, the easier the cleaning procedure will be.
  5. Do not let the product dry on the surface being cleaned. Agitate the solution with a hand brush or mop.
  6. Remove the solution with a mop or, for best results, with a wet/dry vacuum cleaner. For small areas, use a dry cotton rag or sponge.
  7. Rinse thoroughly with plenty of clean water.
  8. Once the floor is dry, buff to a uniform clean using a white nylon pad.

To help prevent deep soiling and staining in the future, apply MB-24 Barrier.
