Area rug soaked by a leak or radiator? How to dry it in the first 24 hours, what to do with the pad, and when to book a wash

A rug that got soaked by a leak can almost always be saved if it dries fast. The trouble starts when it stays wet: a wool rug left sitting on a soaked pad for three or four days can smell for good, show brown tide marks, bleed dye into the light parts of the design, and leave the floor under it cupped or stained. The first day matters more than anything you do later. Here's what to do, in order, and when a wash makes sense.

First, figure out what kind of water it was

This decides almost everything else.

• Clean water. A burst supply line, a dishwasher or washing machine hose, an overflowing sink, rain through a window left open. If you can get it drying within a day, a rug that took clean water usually comes through fine.
• Radiator water. Heat season in New York City runs October 1 to May 31, and the first few weeks of it are when radiators misbehave. A steam radiator in a prewar apartment can spit water from its air valve, and a hot-water radiator can drip from its bleed valve. Either way the water has usually sat in old iron pipes, so it tends to be rusty or gray. Expect brown or orange marks where it pooled, not just a wet patch.
• Water from upstairs. In an apartment building, a ceiling leak is often someone else's overflowing tub, toilet or washing machine. A tub or washer is not clean water, and an overflowing toilet is worse.
• Sewage or outside floodwater. A backed-up drain, a flooded basement on Long Island or in Westchester after a heavy storm, or a river or street flood. This is a health problem before it's a rug problem. Wear gloves, keep kids and pets away, and for an inexpensive machine-made rug, throwing it out is usually the right call. A regular wash is not decontamination, and we are not a water-damage restoration company.

If you rent, tell your landlord or super right away and in writing, so there's a record of when the leak started. In NYC, you can also report an unrepaired leak to 311.

The first hour

1. Take photos before you move anything: the ceiling or pipe, the puddle, the rug, the floor. If the leak is covered by your homeowner's or renter's insurance, or by the neighbor's, the photos are what you'll be asked for. Check your policy; don't assume either way.
2. Get the rug off the wet floor. Water trapped between a rug and a hardwood floor is how floors cup and get dark stains. Roll the rug loosely, face in, and carry it to a dry room. Don't drag it across the wet floor.
3. Separate the pad. A soaked felt or felt-and-rubber pad holds far more water than the rug does and takes days to dry. In most cases it's simpler to throw the pad away and buy a new one in the same size than to try to dry it.
4. Press out what you can. Lay the rug flat on a dry surface and press down hard with old white towels, or stand on them, swapping in dry ones until they stop coming up wet. A wet/dry shop vac pulled slowly across the rug takes out a lot more. Press and pull; don't scrub.

Drying it in the first 24 hours

The goal is to get air moving across both sides of the rug. The U.S. Environmental Protection Agency's guidance on mold is to dry water-damaged items within 24 to 48 hours, and that's a good deadline to hold yourself to.

• Lift it off the floor. Drape a smaller rug over a couple of chairs, a clothes rack or the side of a bathtub. For a larger rug, prop it on something that lets air under it, like a few overturned buckets or plastic crates, or lay it on a dry patio table outside on a dry day.
• Use fans, and a dehumidifier if you have one. Point a box fan at the back of the rug, where the moisture sits, and close the room door with the dehumidifier running.
• Flip it every few hours so the face and the back both get air.
• Keep heat away from it. It's tempting to drape a wet rug over the radiator that caused the problem, or aim a hair dryer at it. Don't. High heat can shrink wool, distort the shape, and melt or crack the latex backing on tufted and many synthetic rugs. Room-temperature air moving fast dries a rug better than heat does.
• Never roll it up or bag it while it's damp, even for a night. A damp rug rolled in plastic is how mildew starts.

What to watch for while it dries

• Dye bleeding. Press a damp white paper towel onto a dark area, especially red, navy or black, and look at it. If color comes off, keep the rug flat and drying as fast as possible, don't rub it, and keep wet fringe from lying against the colored field. Color runs further the longer a rug stays wet.
• Brown edges or a brown ring. Many rugs, including most hand-knotted and many machine-made ones, have a cotton or jute foundation. When cotton and jute get wet and dry slowly, they can wick a brown stain up into the pile, often in a ring where the water stopped. Fast drying is the best defense. Don't try to bleach it out.
• The smell. Wet wool smells like a wet animal, and that's normal while it's damp. A musty, sour smell that's still there two or three days later, or that comes back on a humid day, usually means the rug or the foundation didn't fully dry.
• Stiff, cracking spots. Fold a corner of the area that got wet, gently, and listen. A crunch or a crack in the back can mean the foundation is weakened from sitting wet. That's dry rot, and it's common under potted plants that have been watered over a rug for months as well as after leaks. Don't keep folding it to test.

When to book a wash

A rug that took clean water and dried within a day or two may just need a vacuum. Book a full wash if any of these are true:

• The water was dirty, rusty or from upstairs, even if the rug looks fine once it's dry.
• It left a ring, a brown edge or an orange radiator mark.
• It still smells two or three days later.
• Colors moved.
• It was a dirty rug to begin with. Water mixed with a year of soil in the base of the pile tends to leave a darker outline where it dried.

Our cleaning is a full wash of the whole rug, not a spot treatment. It isn't mold remediation, and a wash can't promise that every water mark or every bit of bled dye will come out, so don't count on that for a rug that was already badly bled or browned. If the rug has weak or cracking areas, holes, or edges that came apart, you can request a repair quote at easyrugwash.com/rugrepair.

There's no need to rush a wet rug into a booking. Dry it first, then book. If you want the pickup on the calendar now, you can book and choose a pickup date a few days out instead of the usual pickup within 48 hours. Rugs come back 7–10 business days after pickup. The timeline post goes through that in more detail.

What it costs

Pricing is by each rug's measured area. Pickup and return are free when the cleaning subtotal is $250 or more, counting every rug in the order. Under $250, pickup and return are a $50 total fee. If furniture has to be moved off the rug and put back, that's an optional +$50.

A leak rarely hits just one rug. If the hallway runner got wet too, add it to the same order; once the cleaning subtotal reaches $250 the pickup fee drops off for both.

To book, measure the rug flat, width by length, without the fringe (the measuring guide shows how), enter the size on easyrugwash.com, and pick a pickup date. If the rug got wet with pet urine rather than a leak, the pet urine guide is the better place to start, and the pet odor page covers that service. More examples are on the rug cleaning cost page. Pickup covers New York City, nearby Long Island and Westchester, North Jersey and southwest Connecticut; see service areas for details.
