carpet dirt

I sit at an area that is slowly darkening where my feet are.
It began when I bought some slippers with a tacky sole.
I threw them out and have tried to clean the area about 16" x 20" with woolite carpet cleaner to no avail.
It says to spray, let dry then vacuum
My question is am I making it worse if the color beneath the tan rug is really dark fiber or should I clean it further to get closer to its natural tan?
Would warm water and mild soap with a lightly agitated brush do?
Or warm water with a mild soap and removing by pressing paper towel on the wet area?
Thank you

 

Part of the problem is dirt/staining of the fibers but if they're wearing down more than those around them, they will stand out from that as well and no amount of cleaning can fix that. I would clean it the best you can and then consider a small mat or rug for that area of the carpet.

 

Is the carpet tan or darker?
This will help me know to wash out not.

 

A lot depends on what is causing the darkening. If it's simply dirt then shampooing should help a lot. That is spraying, scrubbing and thoroughly vacuuming while it's still wet. If some solvents, chemicals or other have come off your shoes cleaning might be more difficult but I would still start with a wet shampooing. If you have a wet/dry shop vac you can use that or you can buy a small carpet shampooer online or rent one from your local home center.

 

I'll try. Thank you.

 

Be careful, scrubbing carpet can take the twist out of the yarn and then that area will be flatter than the rest.

 

I had the rug cleaned two years ago and he said it would not be bumpy. After two years of seeing bumps which he said would not appear if cleaned I called and the same son balked. I finally texted the owner and he sent a crew over. They stretched and cleaned and all is well. It was to cost for the cleaning but the stretch for free but I gave him some money for the stretch and feel good about the whole deal.. Thanks all.
