This is a first for me, I have cleaned oriental rugs for 3 years now, all fabrics and styles. I am not new at this, I trained under a master textile cleaner, and am fully certified by the IICRC. My wife and I bought one from home depot 6 months ago, I had olefin cleaner left in my bottle, so yesterday afternoon I decided to clean the rug on a slower day.

Right away the edges wrinkled in a wave pattern all the way around, maybe 1 ½ to 2 inches high, and finally today they are going down. While cleaning I used high heat, olefin traffic lane cleaner, and had plenty of vacuum to get the rugs dry in 4 hours max, no over wetting at all.

My only guess was the AC wasn’t running, and the humidity was 68% percent (we had a ton of rain in PA), I now have the AC on and the humidity is back down to 48%

Any idea why the rug wrinkled? Its 100% synthetic, the backing is as well.

Even if it's not over-wet, an olefin rug will be wet front to back. I can't definitely answer why, but I do know from experience that it happens from time to time and it's not anything to worry about, as you've noticed. I'm putting my niece through a certification course this Monday and Tuesday with Doug Heifferman. If I have the chance, I'll ask him. It probably has something to do with tension-while-wet variance between the front and back. Anyway, I'll see if I can get a technical answer.

Thanks Michael. One thing to note, while the fabric is olefin, the style is very low pile, not your typical looped olefin

What is it woven over?

The warps are probably cotton and very tight.

You go over it with your truckmount and the water just rolls off the fibers down into the natural warp backing.

The backing fibers swell and then the tension pulls at the spots with the least dimensional stability- the corners.

I checked again, the carpet is 100 olefin, and the tag recomends from Shaw to use hot water extraction

What are the fringes made of? What is the binding/surging made of?

Take a little snip, burn it and see if it smells like paper.

That being said it is not completely unheard of for synthetic fringes and backings to swell and result in shrinking. It is just unheard of for olefin to do that.
