How to Clean Dark Edges on a Carpet

Dark lines around a relatively new carpet can be a nightmare for homeowners. The dark lines can make a home look rundown and poorly cared for. Filtration soiling lines result from dust, pollutants, and air pockets in the floorboards, and they often form near the baseboards. Even with frequent vacuuming, the marks do not come off easily, leaving many homeowners to spend money on professional carpet cleaning. With a few tools and some elbow grease, you can rid yourself of these dark edges and once more take pride in your clean carpet.

Step 1

Dilute the alkaline detergent solution following a standard 1 gallon of water to 2 to 4 ounces of alkaline detergent. Use more detergent for darker stains.

Step 2

Protect your baseboards from damage by inserting a flat square of cardboard between the baseboard and the edge of the carpet pile at a perpendicular angle to the carpet surface.

Step 3

Apply the solution directly to the soiled area, and let the solution stand for 10 to 15 minutes.

Step 4

Agitate the soiled area with the pile carpet rake until the solution lathers. Scrub the area as close to the wall as possible without striking or scuffing the baseboards.

Step 5

Mix 4 ounces of alkaline rinse solution with 1 gallon of hot water.

Step 6

Dig a crevice hammer into a sponge, and blot the excess solution left in the crack of the carpet. Push the sponge as hard as possible into the crack. The crevice hammer might tear the sponge, but you must fully soak up the detergent, or the area will soil rapidly with pollutants and dust.
