VLM Carpet Cleaning: A Basic Instruction Manual

1. Introduction to VLM Carpet Cleaning

Very Low Moisture (VLM) carpet cleaning is a professional cleaning method that uses limited moisture (typically less than 1 gallon per 1,000 sq. ft.) and fast-drying encapsulation chemistry. It’s ideal for both residential and commercial environments due to its quick dry time, eco-friendliness, and cost efficiency.

2. Benefits of VLM Carpet Cleaning

• Dry in under 2 hours

   

• No risk of over-wetting

   

• Green-certified chemical options

   

• Lower equipment cost

   

• Easier to operate solo

   

• Great for maintenance programs

   

3. Understanding Carpet Types and Fibers

Note: Always test a small area before applying chemistry or agitation.

4. VLM Cleaning Chemistry 101

Encapsulation Cleaners
These crystallize dirt and suspend it for easy removal during post-vacuuming.

• pH range: 6.5–8.5 (safe zone)

   

• Application rate: Light mist, not saturation

   

• Popular brands: Releasit, Encap-Clean, VacAway

   

Boosters & Pre-sprays (optional)
Used for heavily soiled areas. Ensure compatibility with encapsulation chemistry.

5. Equipment Overview

• CRB (Counter-Rotating Brush) – Excellent agitation and lifting power

   

• Orbital/OP Machine – Covers larger areas quickly; used with bonnets or microfiber pads

   

• Pump-up or Electric Sprayer – For applying solution evenly

   

• Vacuum – Pre- and post-cleaning (HEPA recommended)

   

• Pads/Bonnet Options – Cotton, microfiber, or synthetic (color-coded for soil levels)

   

6. Step-by-Step Cleaning Process

Step 1: Pre-Inspection

• Identify fiber type and problem areas

   

• Explain process and set expectations

   

Step 2: Dry Vacuum Thoroughly

• Use commercial vacuum

   

• Remove as much dry soil as possible

   

Step 3: Apply Encapsulation Solution

• Use a fine mist sprayer

   

• Cover small areas (100–200 sq. ft. at a time)

   

Step 4: Agitate with Machine

• Use orbital or CRB

   

• Overlap passes, avoid overworking areas

   

Step 5: Dwell Time

• Let solution sit for 5–10 minutes (if needed)

   

Step 6: Bonnet/Padding Pass

• Attach absorbent bonnet

   

• Vacuum

7. Stain and Spot Treatment

Common Stains & Solutions:

• Grease/Oil: Citrus-based gel or solvent spotter

   

• Coffee/Tea: Tannin remover

   

• Pet Accidents: Enzyme spotter followed by encapsulation

   

• Ink: Solvent-based remover (minimal use)
  Always blot, never rub. Rinse and extract using bonnet method.

   

8. Commercial vs. Residential

9. Maintenance and Machine Care

After Each Job:

• Rinse bonnets and pads

   

• Wipe down machine

   

• Check cables and cords

   

Weekly:

• Clean brushes/pads

   

• Inspect belts and bearings

   

Monthly:

• Test sprayer function

   

• Descale chemical sprayer if needed

   

10. Safety and Best Practices

• Use low-pH chemistry only

   

• Wear gloves when handling chemicals

   

• Avoid electrical outlets with water sprayers

   

• Inform client about drying time and safety

   

• Mark off slippery areas during and after cleaning

   

11. Troubleshooting Common Issues

12. Client Communication & Expectations

• Set realistic outcomes (e.g., stains vs. wear)

   

• Explain the dry time.

   

• Offer aftercare tips: rugs, furniture coasters, re-cleaning frequency
