How to get dog poop off shoes, decks, patios, and concrete before the rain sets in

You’re standing on one foot at the back door, holding a shoe at arm’s length, trying to figure out what to do next without touching anything. Everybody who owns a dog in the South Sound has been here, and it usually happens in the dark, in the rain, sometime after the first week of October. So here’s how to get dog poop off shoes properly, and then how to deal with the deck, the patio, and the concrete walkway it came from, because on a wet Pacific Northwest lawn those two problems arrive together.

The short version: cold water, patience, and a brush you don’t care about. The long version is below, along with the part most people skip, which is what happens to all that rinse water once it runs off your patio.

How to get dog poop off shoes without making it worse

The instinct is to scrape the shoe on the grass, then rinse it in the kitchen sink. Both of those are mistakes. Scraping on grass grinds the mess deeper into the tread and reseeds the lawn with whatever was in it. The sink is where you wash dishes.

Do this instead, outside, with a hose:

1. Knock off the bulk first. A stick, a paint stirrer, or an old butter knife works. Scrape from the heel toward the toe so the grooves empty in one direction instead of packing tighter.
2. Rinse with cold water only. Hot water sets protein into porous rubber and canvas the same way it sets a stain in carpet, and once the smell is in there, it stays.
3. Work the tread with a stiff brush. An old dish brush, a nail brush, or a toothbrush for the fine grooves. Add a squirt of dish soap and give it a minute to loosen things before you scrub.
4. Rinse again, thoroughly, and check the sidewalls and the seam where the sole meets the upper. That seam is where residue hides and where the smell survives your first three attempts.
5. Dry them somewhere ventilated. Not the garage floor, not a sealed plastic bin. Damp rubber plus leftover residue is exactly how a shoe starts smelling permanently.

For fabric sneakers that took a direct hit, most machine-washable pairs will survive a cold cycle in a mesh bag after you have removed everything solid. Pull the insoles, wash them separately by hand, and air dry both. Never put them in the dryer.

If the shoe made it into the house before you noticed, the carpet is now the bigger problem, and there’s a specific order of operations for that. We covered it in how to get dog poop out of carpet.

Concrete patios, driveways, and walkways

Concrete looks tough and behaves like a sponge. It is full of tiny pores, and anything liquid that lands on it starts wicking down within minutes. That is why a spot you hosed off in August can still smell in September when the humidity comes back up.

Scoop everything solid first with a bag or a scooper, then rinse the area with cold water and scrub with a stiff outdoor brush. For the residue and the odor, dish soap will get you most of the way, but an enzyme cleaner labeled for pet waste is what actually breaks down the proteins living in the pores instead of covering them. Let it dwell for the time on the bottle before you rinse. Rushing that step is why people conclude enzyme cleaners don’t work.

Two things to avoid on concrete. Skip the bleach, which is hard on surrounding plants and does nothing about the odor once it evaporates. And skip the vinegar on any decorative or stamped concrete, since acid etches a sealed finish and leaves a dull patch that shows up worse than the stain did.

Wood decks need a gentler hand

Cedar and pressure-treated fir decks are everywhere from Gig Harbor to Olympia, and both are softer than they look. The wood is fibrous, the grain runs in channels, and a wire brush will shred it.

Use a nylon-bristle brush, not metal, and scrub with the grain rather than across it. Cold water and dish soap first. If the mess sat long enough to soak in, an enzyme cleaner is worth the wait, but keep the dwell time reasonable on wood since standing moisture on an older deck is its own problem. Rinse and let it dry before you decide whether it still needs work.

Composite decking has the opposite issue. The surface is sealed and nothing soaks in, but the manufactured wood-grain texture is a series of shallow grooves that catch residue and hold it. Scrub along the grooves, not across them, and rinse a wider area than you think you need. Anything you push sideways just relocates the problem to the next board.

Pressure washing before the wet season, and where that water goes

September is the right window to pressure wash a deck or patio around here. The surface is as dry as it will get all year, the moss on the north-facing boards has not taken hold yet, and you still have enough dry days to let everything cure before the rain settles in for the winter.

A few practical notes. Do not point a pressure washer at fresh waste. All you accomplish is aerosolizing it across the siding, the patio furniture, and yourself. Clean the actual mess by hand first, then pressure wash the surface afterward. On wood, keep the wand moving, use a wide fan tip, and stay a foot or more off the boards. Too close and too narrow gouges cedar in a single pass.

Here is the part almost nobody knows. In Tacoma, soapy wash water is not allowed to run into a storm drain. The city’s stormwater pollution prevention guidance says it plainly: pressure washing wastewater carrying soaps, chemicals, or soils is prohibited from entering storm drains. The city’s washing discharge tip sheet draws the line for you. Plain cold water with no soap, no detergent, and no oil in it can go to the storm system or a landscaped area. Add a cleaner and that water is supposed to go to the sanitary sewer instead.

There is a practical version of that rule for a homeowner with a deck brush. Do the soapy part in a bucket, dump the bucket down an inside drain or a utility sink when you are done, and keep the runoff that actually leaves your patio to plain cold water. It matters here because Tacoma’s storm drains are not connected to a treatment plant. They run to the creeks, to the Thea Foss Waterway, and out into Commencement Bay untreated.

The same logic applies to the waste itself. Hosing a pile off the patio and into the grass is not cleanup, it is relocation, and in the rainy season it ends up downstream. There’s a reason we keep saying the dissolvers and rinse-it-away products don’t hold up, and we went through the whole category in why dog poop dissolvers are a waste of money in the PNW.

The last three feet, where most of it actually lands

Almost everything that gets tracked inside crosses the same short stretch: back step, mat, threshold. That’s the part worth defending.

Put a real bristle mat outside the back door, the coarse kind that scrapes rather than the soft kind that just gets damp. Add a washable mat inside. If you have a covered porch or a mudroom, a boot tray with a lip contains the drips instead of spreading them into a hallway. Garage floors are usually sealed or painted concrete, so the same approach works there as on a patio, and a bag of clay-based absorbent from the auto parts store is genuinely useful for anything that ran.

Keep a designated pair of yard shoes by the door and the problem mostly stops being a problem. Nobody wants to hose down a good pair of sneakers at nine at night.

Why October changes the equation around here

From late September through March, western Washington yards stop drying out. Ground that was firm in August turns soft, waste that used to crust over on the surface stays wet and pliable for weeks, and every trip across the lawn moves some of it toward the hard surfaces where you actually walk.

That’s not just an inconvenience. Hookworm larvae in contaminated soil stay infective for weeks to months and can burrow through bare skin, which is why VCA’s guide to hookworm in dogs warns about walking barefoot on ground where waste has been. Cool, damp, shaded conditions are exactly what those eggs and larvae prefer, and cool, damp, and shaded is a fair description of most South Sound backyards between Halloween and Easter. So the deck you scrub in October is worth scrubbing properly, and the yard behind it matters more in winter than people assume. If you want the deeper version, our post on what actually kills bacteria in a yard covers which products do real work and which ones just smell like they do.

Odor follows the same pattern. Warm, wet, and enclosed is the worst combination for a covered patio or a fenced side yard, and the smell that shows up on a mild wet January afternoon usually came from something you rinsed off in the fall rather than removed. We broke that down in dog waste odor control for PNW yards.

Stop it at the source

Every one of these cleanups starts the same way: a pile in the grass that somebody stepped in. Clear the yard consistently and the deck stays clean, the patio stays clean, the shoes stay clean, and the carpet never enters the conversation.

That’s the job we do. Weekly and twice-weekly dog waste removal across Pierce, Kitsap, and Thurston counties, from Tacoma and Lakewood to Puyallup, Gig Harbor, Olympia, Bremerton, and Silverdale. We show up, the yard gets cleared, and the wet season becomes somebody else’s problem.
