VFI®-1009 Cleaning Detergent

VFI®-1009 Cleaning Detergent

VFI-1009 Cleaning Detergent is a 100% biodegradable, water-based, general-purpose roof cleaner. It is an essential part of surface preparation to remove grease, oil, tough soils, and other contaminants from roofing substrates. The detergent ensures the roof is clean and free of residue before a primer, coating, or foam is applied. Starting a commercial roof restoration project with a prepared membrane will guarantee the adhesion of subsequent roof coatings to the surface. VFI-1009 is a versatile cleaner that pretreats masonry, concrete, deck, roof, and wall surfaces. Packaged as a cleaning concentrate, it requires a 1:10 dilution with water to remove tough stains. It works well in locations that limit the use of hazardous cleaning chemicals due to environmental regulations.

Eco-friendly detergent concentrate that thoroughly cleans existing roof membranes.

Features & Benefits

  • Enhanced adhesion – allows for better adhesion of a primer
  • Biodegradable formula – safe for use in areas with strict VOC regulations
  • Multipurpose – formulated for use on roofing substrates, decks, and walls
  • Easy to use – can be applied by sprayer, roller, or brush and rinsed with water
  • Tough cleaner – cleans and degreases without the use of harsh chemicals
  • 10:1 dilution – concentrated formula for increased useable material

Instructions for Use:

Surface Preparation

Remove large amounts of dirt, leaves, and debris from the roof with a broom. Inspect the roof, including flashing, seams, vents, metal caps, etc., and repair as needed. A chlorine solution can be used to treat areas with algae, mildew, or fungus growth. Remove rusting and other oxidation with a grinder or wire brush. Rinse off cleaning agents and allow the surface to dry before using the cleaning detergent.


VFI-1009 Cleaning Detergent must be diluted at a ratio of 1 part cleaning detergent to 10 parts water. Measure the amount of water needed in a bucket and add the concentrate afterward before mixing. The material should be brought to a minimum temperature of 65°F and mixed until uniform before use. Mix times will vary depending on the mixing method and volume.

Apply VFI-1009 with a brush, roller, or single-component sprayer to the surface at a rate of 150-400 square feet per gallon. The total amount of cleaner you will need is specific to the job/application. Allow the solution to stand on and saturate the substrate for at least 15 minutes, and then scrub with a stiff bristled broom or brush. Spot treating may be needed to ensure the substrate is completely clean. Use a pressure washer capable of achieving a minimum of 2000 PSI to remove the remaining material with clean water until all soap bubbles are gone. On roofs with a slope, work from the lowest point to the highest and then back down for a double rinse. On flat roofs, work away from the drains and back.

After cleaning, allow the surface to dry thoroughly before proceeding with the application of any primers, foams, or roof coatings. Drying time will depend on temperature, humidity, and air movement.


Use water to clean any equipment used to apply VFI-1009. If sprayed, flush water through the spray lines until the detergent is completely removed.


*Always read the safety data sheet before working with chemicals

Use chemicals only as directed and for their intended purpose. Do not dispose of chemicals down the drain. Most chemicals must be disposed of as hazardous waste.

PPE to avoid all unnecessary exposure:

  • Eye protection – safety glasses or goggles are recommended
  • Hand protection – wear chemically resistant protective gloves (nitrile, butyl, or neoprene)
  • Skin and body protection – wear suitable protective clothing
  • Respiratory protection – in case of insufficient ventilation, wear suitable respiratory equipment. Respirator selection must be based on known or anticipated exposure levels, the hazards of the product, and the safe working limits of the selected respirator

Product Limitations

As a water-based product, VFI-1009 must be protected from freezing.

  • Incompatible materials – strong oxidizing agents
  • Conditions to avoid – incompatible materials
