Is Dawn Soap Good for Carpet?

Dawn is a spot treatment for a synthetic carpet, not a solution for a carpet cleaner's tank. Diluted and rinsed out, it handles a spill; tipped into the machine, it's a product the machine was never built around. P&G sells a carpet extraction cleaner as a separate line for the second job, and that is not the bottle under your sink.

Is Dawn Soap Good for Carpet Cleaner

In a tank, dish soap is the wrong product, and the best soap to use on carpets is the formula sold for the machine. In-tank products are certified on resoiling, optical brighteners, lightfastness and pH, and dish soap has been tested on none of them. For a spot, the best thing to clean a carpet with is a quarter teaspoon of non-bleach, non-lanolin liquid dish soap in a cup of lukewarm water.

Machine makers want their own formula in the tank, and the reason comes back to the rinse, which is where the question of is there a carpet cleaner that actually works starts. Bissell's guides tell owners that other formulas may harm the machine, and a tank puts soap into every fibre in the room at once, with nothing behind it to take the soap back out.

Rental terms state that rule at its strictest, and the machine in your closet runs on the same logic: the tank takes what the maker made for it, and the stain does not get a vote.

Find the line that matches your room and your mess.

• A dried ring where a mug went over, or one grey drip in front of the sofa. Use the dish-soap dilution, dabbed on with a cloth, blotted, then rinsed with clean water and blotted dry. Skip the rinse and the spot comes back darker, because detergent left in the pile attracts soil to the same place.
• A pet accident you can smell at the baseboard and cannot find. Blot it, flood the spot with cool water, and work in an enzyme treatment made for pet stains. The microbes release enzymes that break down the proteins, urea and uric acid in urine, and a damp towel pressed over the spot keeps them working. Keep heat away from the spot, because a steam cleaner sets the stain and the smell.
• A dried brown patch of vomit or blood. Oxygen-action cleaners rather than enzymes suit coloured stains such as these, and the damp towel does the same job here: cover the spot, let it sit, blot it out.
• A whole room gone grey along the traffic lanes, on a weekend you have set aside. Rent a deep cleaner: one clean costs less than buying, and there is no machine to store between cleans. Cleaning solution is not included with the rental, so pick it up with the machine.
• Traffic lanes that grey over again every few months. Buy the best home carpet cleaner, a corded upright: the Bissell ProHeat 2X Revolution Pet Pro Plus carries a 1-gallon clean tank, a 25-foot cord and a 5-year limited warranty.
• A stair tread, or one patch of carpet where an upright will not fit. A portable earns its shelf space: the Bissell Little Green Pet Pro holds 64 ounces of clean water and a 48-ounce dirty tank, and carries a 3-year limited warranty.

Rug Doctor's own upright is the Pro Deep, the machine it calls the same one you can rent, with two removable 1.5-gallon tanks and a 48-ounce bottle of Oxy Deep. The answer to is bissell or rug doctor better turns on the room and the mess.

Is Dawn Soap Good for Carpet Stains

On synthetic pile, yes: a stain is what dish soap is for. What should you not use Dawn dish soap on? Leather, upholstery and any fabric that will not be rinsed afterwards, which share one trait.

What separates a carpet from that list is the rinse. A synthetic pile can be flooded with clean water and blotted dry, while leather, upholstery and a wool rug cannot, so the dish-soap method stops at the carpet. Wool takes a cleaner made for wool instead, which is where the wool note above leaves it. Automatic dishwashing detergent and laundry detergent are not substitutes for the liquid dish soap.

How long should Dawn dish soap sit on a stain? Minutes, not hours. Spot sprays are told to sit for 30 seconds to five minutes and no more, and a dish-soap dab belongs inside that same short window: work it in, keep it inside those five minutes, then blot and rinse.

A dish-soap spot on a synthetic pile is finished in minutes: diluted, worked in, blotted, rinsed. Everything dish soap gets wrong on a carpet comes back to leaving too much of it in the pile.
