How to clean carpet

This guide covers deep cleaning carpet with a carpet extractor, from vacuuming and pretreating to rinsing and fast drying. You end up with clean carpet that has little soap residue left in it, so it stays clean longer.

What you'll need

Also have on hand: vacuum, carpet extractor, foil squares or plastic furniture blocks, fans, dehumidifier, carpet rake

Steps

  1. Step 1: Vacuum the carpet thoroughly, going slowly and making passes in crossing directions. Most carpet soil is dry dirt, and the extractor will only turn it into mud.

  2. Step 2: Move the furniture out of the area. Put foil squares or plastic blocks under the legs of anything that stays so it does not stain the wet carpet.

  3. Step 3: Test the carpet spotter (MIPI-74) on a hidden spot first to make sure the carpet color does not run.

  4. Step 4: Spray traffic lanes and spots with the carpet spotter (MIPI-74) and let it sit 5 to 10 minutes.

  5. Step 5: Fill the clean tank with hot tap water, never boiled water. Add extraction cleaner (MIPI-11) at about half the amount the label calls for, since leftover soap makes carpet get dirty again fast.

  6. Step 6: Start in the corner farthest from the door and work back toward it so you never walk on cleaned carpet.

  7. Step 7: Make a wet pass by holding the spray trigger, pushing forward slowly and pulling back slowly. Overlap each stroke by about 1 inch.

  8. Step 8: Release the trigger and make 2 slow dry passes forward and back. Watch the recovery tank and move on when barely any water is coming up. Overwetting causes mildew, shrinkage and brown spots wicking up from the backing.

  9. Step 9: Empty the recovery tank often as you work.

  10. Step 10: Rinse each room once it is done. Empty the clean tank, refill it with plain hot water and go over the carpet again to pull out leftover soap.

  11. Step 11: Dry the carpet fast with fans aimed across it, AC or a dehumidifier running, and windows open if it is dry outside. Aim for under 6 to 8 hours, because anything over 24 hours risks mildew.

  12. Step 12: Groom the damp pile with a carpet rake if you want a more even, finished look.

  13. Step 13: Clean the machine by rinsing both tanks and clearing hair off the brush. Store it with the tank lids off so it does not smell next time.
