How to clean artificial grass: the short version
Artificial grass does not need mowing, watering or fertilizer, but it is not self-cleaning. Leaves land on it, dust settles into it, dogs use it, and drinks get spilled at cookouts. The good news is that cleaning a synthetic lawn is quick and mostly involves water and a brush. The less obvious news is that how easy it is depends almost entirely on what is under the turf. A lawn built on a compacted, permeable base with the right infill rinses clean in minutes; one laid over poorly draining soil holds water, traps odors and grows algae no matter how often you hose it. That is why we talk about cleaning and artificial grass installation done right in the same breath.
The weekly cleaning routine
For a lawn with ordinary foot traffic and no pets, a once-a-week pass keeps synthetic grass looking new. Here is the sequence professional maintenance crews follow.
- Clear debrisUse a leaf blower on a low setting or a plastic leaf rake to remove leaves, twigs and pet hair. Avoid metal rakes, which can snag and pull fibers. If you have a lot of trees, a dedicated artificial grass vacuum picks up fine debris without pulling infill.
- Rinse with a hoseA regular garden hose with a spray nozzle is all you need. Work from the high side of the yard toward the drainage side so dust and pollen wash through the backing rather than pooling.
- Spot-treatFor sticky spots, bird droppings or food, mix a few drops of dish soap in a bucket of warm water, apply with a sponge or soft brush, and rinse. For anything organic, a 50/50 mix of white vinegar and water works and is safe for fibers and infill.
- Brush against the grainFinish with a stiff synthetic-bristle push broom, sweeping against the lean of the fibers. This lifts flattened blades, redistributes infill and keeps high-traffic paths from matting.
Pro tip: check the direction the fibers lean before brushing. Turf is manufactured with a grain, and brushing with it flattens the lawn further. Always brush into the grain.
How to clean artificial turf with dogs
Pet owners are the people who most often ask how do you clean artificial grass, because urine odor is the real test of a synthetic lawn. The approach is simple when the base drains:
- Solid waste: let it firm up, pick it up as you would on real grass, and rinse the spot.
- Urine: rinse the area daily in hot weather and at least a few times a week otherwise. Water is what carries urine through the backing and into the base where it percolates away.
- Odor control: apply an enzyme-based turf cleaner or a diluted vinegar solution to the pet zone every week or two. Enzymes break down the uric acid crystals that plain water leaves behind.
- Infill matters: lawns installed with an antimicrobial or zeolite infill hold far less odor than those with plain silica sand, because the infill itself absorbs ammonia until the next rinse flushes it.
If odor persists despite regular rinsing, the problem is usually below the turf: either the base is holding water because it was not built with a permeable aggregate and proper slope, or the turf backing has a low drainage rate. Both are installation decisions, and both are hard to fix without lifting the turf.

Deep cleaning once or twice a year
Even with a good weekly routine, the best way to clean artificial grass over the long term includes a seasonal deep clean. Pick a dry day, ideally in spring and again in fall.
| Task | How | Why it matters |
|---|---|---|
| Full rinse and detergent wash | Hose the whole lawn, apply diluted mild detergent with a soft brush, rinse thoroughly | Removes accumulated dust film that dulls the color |
| Power brooming | Rent or hire a power broom for artificial turf and run it against the grain | Lifts matted fibers and levels infill far better than a hand broom |
| Infill top-up | Spread a light layer of matching infill in thin spots, then broom it in | Keeps fibers supported and the backing weighted down |
| Weed and moss check | Pull any seedlings at edges; treat moss with a turf-safe moss remover | Weeds root in debris on top of the turf, not through a properly installed weed barrier |
| Seam and edge inspection | Walk every seam and perimeter looking for lifting or gaps | Catching a loose seam early means a quick glue repair instead of a wrinkle |
What not to do when cleaning synthetic grass
Avoid
- Pressure washers on a narrow fan or close range (they blast out infill and can split seams)
- Wire brushes and metal rakes
- Bleach, solvents, paint thinner or acetone near the fibers
- Hot coals, grills or fire pits placed directly on turf
- Letting leaves sit wet for weeks, which invites moss
Use instead
- A garden hose, or a pressure washer only on a wide fan held well back
- Synthetic-bristle brooms and plastic rakes
- Mild dish soap, diluted vinegar or enzyme turf cleaners
- Pavers or a mat under any heat source
- A quick blow-off after storms
Why drainage decides how easy cleaning is
Every method on this page assumes that when you rinse, the water goes somewhere. On a properly built synthetic lawn, the turf backing is perforated or fully permeable, the infill is a loose, permeable sand or mineral, and beneath that sits several inches of compacted, open-graded aggregate with a slight slope. Rinse water carries dust, pollen and pet waste straight down and away. Cleaning takes ten minutes.
On a lawn laid over native clay, or on a base that was never compacted and has settled into low spots, rinse water sits in the backing. Dirt stays, odors build, algae forms a slick film, and the owner concludes that artificial grass is hard to clean. It is not; that lawn was installed wrong. If you are planning a new synthetic lawn, the single most useful thing you can do for future maintenance is choose professional turf installation from an experienced crew that builds a real drainage base and specifies the right infill for pets. The local installers we work with treat base prep as the core of the job, and that shows up every time you pick up a hose.
Cleaning artificial grass FAQ
How do you clean artificial grass after a dog has used it?
Pick up solids, then rinse the area with a hose so urine moves through the backing. Once a week or so, apply an enzyme turf cleaner or a half-and-half vinegar-and-water mix to the pet zone, let it sit a few minutes, and rinse again. Lawns with zeolite or antimicrobial infill need this less often.
What is the best way to clean artificial grass without damaging it?
Blow or rake off debris, rinse with a garden hose, spot-clean with mild soap or diluted vinegar, rinse again and brush against the grain with a stiff synthetic broom. Skip wire brushes, solvents and close-range pressure washing.
How often should you clean artificial turf?
Weekly rinsing and brushing is enough for most lawns. Pet areas should be rinsed every day or two in hot weather. Plan a deep clean with a power broom and infill top-up once or twice a year.
Can you use a pressure washer to clean artificial turf?
Only carefully. Use the widest fan tip, keep the wand well above the surface and sweep in the grain direction. Close-range pressure blasts infill out of the turf and can lift seams. A hose does the same job with less risk.
Why does my artificial grass smell even after cleaning?
Persistent odor almost always means water is not draining through the base, so urine sits in the backing and infill. The fix may be as simple as adding zeolite infill, but if the base was built on non-draining soil without slope or aggregate, it may need to be rebuilt by an experienced installer.
