How to clean artificial grass: the weekly, monthly and twice-a-year routine

Nothing on this list costs much, and most of it is already in the garage.

• Leaf blower. The single most useful turf tool. Debris that is blown off cannot break down into the infill.
• Garden hose with a shower or fan nozzle. Not a jet setting, and not a pressure washer.
• Synthetic-bristle push broom. Stiff nylon or poly bristles, 18 to 24 inches wide. No wire, no metal rake.
• Enzyme cleaner labeled for pet turf. A concentrate and a pump sprayer cost less over a year than ready-to-use bottles.
• Plastic scraper for anything stuck, and a bucket of mild dish-soap solution for anything greasy.
• A steel ruler to check infill depth a few times a year.

Pick up solid waste daily if you have a dog, and do the rest once a week, in the evening when the turf is cool.

1. Blow off leaves, needles, pollen and the neighbor's grass clippings. Start at the house and work toward the edge you can rake from.
2. Rinse the pet zone for two or three minutes with the hose on a shower setting. Aim down through the turf, not across it. This moves fresh urine down and out before bacteria get to work on it.
3. Spot-treat the corner the dog uses most with enzyme cleaner and leave it. It does not need rinsing.
4. Look. Anything green in the shade, anything white on the surface, any edge lifting. Five seconds now saves a service call later.

A yard with no pets can skip to the monthly list and blow off every couple of weeks in pollen and leaf season.

1. Blow the whole yard, including under furniture and along the fence line where debris collects.
2. Brush against the grain. Turf fibers lean one direction from the factory. Brushing against that lean stands them up and lifts the organic layer that has settled in. Paths and the pet zone first, then the rest. Our page on brushing and fluffing covers technique.
3. Rinse everything from the high side toward the low side, roughly five minutes per hundred square feet, until the runoff at the low edge runs clear.
4. Treat. Enzyme cleaner over the whole pet zone, not just the favorite spot. Let it dwell at least twenty minutes while the turf is still damp.
5. Brush again once it has dried. This is the pass that makes it look new.
6. Check infill depth with the ruler in the pet zone, on the main path and in the middle. The ruler test takes two minutes.

On the Grand Strand, two dates matter. The first is mid to late April, after the pine pollen has finished and the live oaks have dropped their leaves. The second is late November, after the last leaves are down and before the wet winter. The coastal calendar explains why.

The deep clean is the monthly routine with three additions. Rent a power broom for the day, or borrow one, and run it against the grain over the whole yard; it lifts what a push broom cannot. Add infill wherever the ruler shows the sand more than about three-quarters of an inch below the fiber tips. And walk the shaded strips and the fence line looking for the green or black film that means algae has started, because it is a five-minute treatment in April and a service call by August.

People spray cleaner on a dirty lawn, rinse it off and wonder why nothing changed. The organic layer of pollen, dust and broken-down leaf litter sits on top of the infill, and any cleaner you apply sits on top of that. Blow first so the loose debris is gone. Brush second so the layer is lifted out of the fibers. Rinse third so it is carried down and out. Only then does an enzyme or an antimicrobial reach the residue it is meant to treat. The final brush after drying is partly cosmetic, but it also stands the fibers back up so the next week of debris blows off instead of settling in.

• A pressure washer. Blows the infill out in stripes, frays fiber tips and can lift seams. Volume flushes; pressure destroys.
• Chlorine bleach. Lightens fibers, weakens backing, kills the border plants and does not remove the organic layer the problem lives in.
• A wire brush or metal rake. Splits fibers, which then mat and shed.
• Solvents of any kind on stains. They soften polyethylene fibers.
• A bag of sand on top of a smell. Buries it for a month.

The routine keeps a clean yard clean. It does not fix a yard that already smells on humid mornings, has black film in the shade, has paths that stay flat after brushing, or has never had the infill touched since it was installed. Those need a power brush, a high-volume rinse and treatments applied in sequence, which is a service visit. An Essential Clean for a people-only yard runs $199 for up to 500 square feet and $249 for up to 1,000. A Premium Restoration, which adds the enzyme, antimicrobial and algae treatments and measures the infill, runs $299 and $399 for the same sizes. Full bands are on the pricing page, and our frequency guide tells you which yards need which.
