Carpet fibers, and why it changes everything

Nylon

The best fiber for cleaning, and the one you want if you are choosing.

Nylon takes heat well, which matters because hot water extraction works better hot. It has genuine resilience, so crushed pile recovers rather than staying flat. And it releases soil more completely than the alternatives.

If you have nylon, expect the best result available. It was the standard in better carpet through the eighties and nineties, which is why some twenty-five-year-old Scottsdale carpet cleans up better than ten-year-old builder carpet.

The one weakness: nylon is vulnerable to acid dyes, meaning red drinks and some foods can permanently stain it. That is a dye reaction rather than soil, and it does not extract.

Polyester and triexta

What most newer carpet is, because it costs less than nylon.

Excellent against water-based staining. Polyester is naturally hydrophobic, so spills sit on it rather than soaking in, and you get more time to blot.

Poor against oil. The same property that repels water attracts oil, so body oil, cooking residue and the grease that comes in on shoes bond to the fiber and hold. That is why polyester traffic lanes go dark and stay dark.

The fix is pre-treatment aimed at oil rather than general soil. It is a different product and a different dwell time, and it is why identifying the fiber matters even on a carpet nobody would call delicate.

The other weakness is resilience. Polyester crushes and does not spring back the way nylon does. What looks like soil in a lane is frequently crushed fiber, and cleaning does not stand it back up.

Olefin

The one that produces the most confusion, and the confusion has a cause.

Olefin is solution-dyed, meaning the color runs through the fiber rather than sitting on it, so it is extremely resistant to bleaching and fading. Excellent in a sunny room.

The problem is wicking. Olefin releases soil easily, which sounds good, but it also lets moisture carry material back up from the backing as it dries. So a spot extracts cleanly, looks perfect while damp, and reappears the following morning as the carpet finishes drying.

That is not a failed cleaning. It is olefin doing what olefin does, and it needs a drier extraction approach and sometimes a second pass once dry.

If your carpet has ever done that, it was almost certainly olefin, and a cleaner who did not warn you either did not know or did not say.

Wool and wool blends

The most demanding and the most rewarding when handled right.

Browns permanently if over-wet. Damaged by high-pH chemistry. Both failures are invisible until after they have happened and neither is recoverable.

Handled properly, wool cleans beautifully and lasts longer than any synthetic. Its own page covers this in full.

How to tell what you have

Rough guidance if you want to check before ringing, though we confirm properly on site.

• Press your thumb into the pile and release. Strong spring back suggests nylon or wool. Slow or no recovery suggests polyester
• Feel the surface. Olefin feels slicker and slightly waxy. Wool feels warmer and softer
• Look at a sunny area against a shaded one. Fading suggests nylon or polyester, since olefin barely fades
• Check whether spots have ever reappeared after a previous cleaning. That points strongly at olefin
• Find the original paperwork if you still have it, which settles it immediately

Why this is on the website

Because the single biggest variable in whether you are happy with a carpet cleaning is whether the person doing it knew what your carpet was made of.

It costs a minute to check. Running the same product and the same moisture across every job is faster, and it is how wool gets browned, olefin gets wicking, and polyester lanes stay dark because they were treated for the wrong kind of soil.
