Without any pics or fiber content, it's hard to say. I surface clean rugs in my shop. I use the appropriate solutions for the type of rug. After dusting/vacuuming, I prespray with a proper prespray, then use a rotary machine with a tank and shower feed to scrub the rug, then rinse with a powerful portable or sometimes the truck mount. Then groom and hang to dry. There are tons of products out there. Use wool products on wool rugs. Use stronger products on synthetics. Beware of viscose rugs.What is the best product to use on these cheap dirty rugs, I just want them clean am not worried about re soiling and such. I clean them in shop but do not have a pit .
MehCheap greasy rugs need a pressure washing gun with a high ph treatment on a concrete slab
