What will not come out

Worn traffic lanes

The most common disappointment in this trade, and the most misunderstood.

A traffic lane looks darker than the carpet beside it, so people assume it is dirtier. Frequently it is not. It is physically worn. Years of grit underfoot have abraded the fiber, splitting the tips and changing how the strip reflects light.

Clean it perfectly and it will still read differently, because the carpet in that lane is genuinely a different texture from the carpet next to it.

Cleaning removes the grit that is causing further wear. It cannot undo the wear that has already happened.

That is the argument for cleaning on a cycle rather than waiting until lanes appear. By the time you can see a lane, the damage is done.

Permanent staining

The distinction that matters is whether something sat on the fiber or changed the fiber.

Soil, grease, food, most drinks and most accidents sit on and in the fiber, and a proper clean lifts them. That is the majority of what is in a carpet.

Anything that chemically altered the dye is a different matter. It is not sitting there waiting to be removed, the color of the carpet in that spot has changed, and there is nothing to extract.

We will tell you which category a given stain falls into during the walkthrough. Frequently we can tell by looking, and occasionally we test a corner of it before committing.

Bleach spots

Its own category because people rarely know what caused them.

A bleach spot is color that has been stripped out of the fiber. Household cleaners are the usual culprit, and so are acne medication on a bathroom mat, benzoyl peroxide on a bedroom carpet, and some pet stain products bought off a shelf.

The fiber is undamaged and the dye is gone. There is nothing to clean off, and cleaning around it makes it more obvious rather than less, because the rest of the carpet gets brighter.

Repair by re-dyeing exists as a trade. It is not something we do, and we will say so rather than cleaning it and hoping you do not notice.

Pet urine that has reached the pad

The biggest one, and it has its own page because it comes up constantly.

Urine in the fiber responds to treatment. Urine in the pad does not respond to surface cleaning, because surface cleaning never reaches it. That is why the smell returns a week later and people conclude the treatment failed.

It did not fail. It only ever addressed the top layer. The full explanation, including when the honest answer is replacement, is here.

Carpet that is simply finished

Sometimes the answer is that cleaning is not the right purchase.

Carpet with delamination, where the backing has separated. Carpet with wear so advanced the backing shows through in the lanes. Carpet that has been repeatedly over-wet and has developed odor in the pad across a wide area.

In those cases we will tell you the money is better spent on replacement, and that conversation happens on the phone or at the walkthrough rather than after you have paid.

It costs us jobs regularly. It is also the only version of this that is worth anything to you.

What does come out

Worth ending here, because the page is not an argument against cleaning.

The majority of what is in a Mesa carpet is fine abrasive grit at the base of the pile, and it comes out. So does general soil, most food and drink, pet hair and dander, and a great many spots people had written off.

Removing the grit is also the single biggest thing that extends carpet life here, because it is the grit doing the cutting. That benefit is invisible and it is the most valuable part of the job.
