Material Safety Data Sheet




ALKEN® SURFACE CLEANER 874 is a proprietary blend of concentrated surfactants and bio-stimulating agents. ALKEN® SC 874 quickly and effectively removes surface stains resulting from spilled petroleum products on concrete, asphalt, rock, and soil. Used alone or in conjunction with ALKEN CLEAR-FLO® 7036, ALKEN® SC 874 decreases the time necessary for clean-up and increases the bio-availability of the contaminant. Can be used as a substitute for ALKEN® CITRUS DEGREASER 872. Safe and effective parts-wash.. See also microbial product made from this product, ALKEN CLEAR-FLO 5100


 Appearance Cream to white opaque liquid
 Odor Mild ammonia or "wild hyacinth" fragrance added
 pH 12.2 - 12.8


  • Rapidly cleans surfaces of oil spills and stains
  • Cleans oily equipment, vehicles and tools
  • Contains no petroleum distillates or solvents
  • Contains essential microbial nutrients
  • Enhances biodegradation above and below ground surface when used as recommended.
  • Ecologically sound.


Hard Surface Cleaning: Dampen the contaminated surface, apply SC 874 and allow it to work for 10 -15 minutes, then brush and rinse. Keep the work site damp during treatment and repeat if necessary.

Porous Surface (soil) Cleaning: Scrape surface, dampen and apply SC 874. Scrape the surface again and rinse. To accelerate biodegradation of the petroleum products, follow with CLEAR-FLO® 7036.

Precautions/Limitations: Read and follow precautions on MSDS. Pretest new equipment finishes by applying to a small area first. Optimal performance is on damp concrete surfaces.
