What Happens in a Rug Wash Pit — Our Full Cleaning Process

A hand-knotted rug holds a surprising amount of dry soil in its foundation — soil that a vacuum or an in-home cleaning machine cannot reach. The full wash process exists to remove that embedded grit, along with odors, stains, and anything else that has worked its way into the pile and foundation over years of use. Here is exactly what that process looks like at our facility in Chamblee.

Before getting into the steps, it helps to understand why in-home surface cleaning — whether by a carpet cleaning company or a rental machine — is not the same thing as a proper rug wash.

Carpet cleaning equipment is designed for wall-to-wall carpet. It applies a cleaning solution, agitates the surface, and extracts moisture. For a hand-knotted rug, that process cleans the top of the pile but leaves the foundation largely untouched. The dry soil that has settled into the base of the knots stays there. Odors that have penetrated the foundation stay there.

More importantly, in-home cleaning does not allow for controlled drying. A wet rug left on a pad, on a wood floor, or in a humid room is a rug at risk for mildew, dye migration, and dry rot in the cotton foundation. Georgia summers make that risk worse.

The full wash process addresses all of this.

The first step is mechanical dusting — removing the dry soil before the rug gets wet. We use a dusting machine that beats the back of the rug while it moves through, loosening the grit that has settled into the foundation. The amount of dust that comes out of a rug that looks clean on the surface is usually surprising.

Skipping this step means washing that soil into the rug rather than out of it.

Before the rug goes into the wash pit, we inspect it and pre-treat any problem areas — pet stains, food stains, heavy soiling in traffic areas, or spots where dyes may be unstable. Pre-treatment gives those areas more dwell time with the appropriate cleaning agent before the full wash begins.

We also test dye stability at this stage. Some rugs, particularly older pieces with vegetable dyes or certain synthetic dyes, will bleed if washed aggressively. Knowing that before the rug gets wet lets us adjust the process.

The rug goes into the wash pit — a large, shallow basin — where it is fully submerged and hand-washed with a pH-appropriate cleaning solution. We work the solution through the pile and foundation by hand, using soft brushes on the pile surface.

This is the step that actually cleans the foundation. Full submersion allows water and cleaning solution to move through the entire structure of the rug, not just the surface.

After washing, the rug is rinsed thoroughly until the water runs clear. Residual cleaning solution left in the foundation can attract soil and cause the rug to re-soil quickly after cleaning. A complete rinse is not optional.

This is where most in-home cleaning falls short. After rinsing, we extract as much water as possible and then hang the rug vertically in a climate-controlled drying room. Vertical drying allows water to drain out of the foundation rather than pooling at the bottom. Controlled airflow and temperature prevent mildew from forming during the drying period.

A rug dried flat on a concrete floor — or worse, folded — is a rug that will develop mildew in the foundation. In Atlanta's humidity, that can happen within 24 to 48 hours.

Once dry, the pile is groomed with a soft brush to restore the nap direction and even out the surface. This is also when we check for any areas that need additional attention before the rug goes back to the customer.

Before the rug leaves our facility, we do a final inspection — checking the pile, the fringe, the edges, and the back. If we find anything that needs to be addressed, we contact the customer before returning the rug.

How long does the full wash process take? Most rugs are ready within five to seven business days. Rugs with significant staining, odor treatment, or repair work take longer. We will give you a realistic timeline when we pick up the rug.

Can all rugs go through the full wash process? Most hand-knotted wool and cotton rugs can. Silk rugs require a modified process with lower agitation and different drying conditions. Very fragile antique rugs may need a gentler approach. We assess each rug individually before washing.

Is the full wash process necessary every time? No. How often a rug needs a full wash depends on foot traffic, whether pets are in the home, and the environment. A rug in a low-traffic room might go five to seven years between full washes. A rug in a high-traffic area with pets might need it every two to three years.
