A Comprehensive Guide to Cleaning the Dirtiest Carpets

Best Carpet Cleaning Procedures

1. **Dry Soil Removal:**

- Begin by vacuuming the carpet to eliminate as much dry soil as possible. Removing dry soil before applying any cleaning solutions is more effective. For dense pile commercial carpets, consider using a powerful vacuum.

2. **Carpet Cleaning Stain Removal:**

- Pre-spotting every stain on heavily soiled carpets is often unnecessary. However, certain stains like those from colored beverages, pet accidents, or mustard may not come out with regular cleaning. Many stain removers perform better on dry carpets as the dry fibers absorb the product more deeply without moisture dilution.

3. **Carpet Cleaning Prespray:**

- Apply a prespray like Firestorm or Ultrapac to tackle heavy soil and grime. For enhanced cleaning and color brightening, add 1/2 ounce of Booster per gallon of ready-to-use prespray. For dealing with oil and grease, mix Citra Quick into the prespray, using at least one ounce per gallon.

4. **Agitation:**

- For carpets with heavy soil, mechanical agitation might be necessary. Options include using a Counter-rotating brush machine like the CRB, a Lo Boy machine with brushes or synthetic scrub pads, or an RX-20 rotary extractor.

5. **Extraction:**

- Perform the extraction process using the Truck mount machine to remove the cleaning solution and soil from the carpet.
