TL;DR
A patio and outdoor living clean covers three material families in one space: hardscape underfoot, furniture and soft goods, and shade structures overhead. Each needs a different method, which is why patios take longer than their square footage suggests. Most households do a spring opening and an autumn closing, with a light mid-season reset if the space gets heavy use.
Three Jobs in One Space
An outdoor living area is rarely one surface. A typical patio combines concrete, pavers, or stone underfoot, metal or resin furniture with cushions, a grill or outdoor kitchen, a pergola or umbrella overhead, and often lighting and an outdoor rug.
Cleaning that space with one method and one product is how furniture gets faded and stone gets etched. A scope that lists each element separately is a scope you can actually evaluate.
What Is Usually in the Scope
Hardscape. Concrete, pavers, flagstone, brick, or tile. Cleared, treated for organic growth, washed at a pressure appropriate to the material, and edges detailed.
Furniture. Frames washed, cushions and fabric slings cleaned according to their material, glass tabletops cleaned, and hardware wiped.
Shade structures. Pergolas, awnings, umbrellas, and shade sails brushed and washed with low pressure. Fabric needs the manufacturer's guidance.
Fixtures and features. Outdoor lighting, ceiling fans on covered patios, outlets and switch covers, planters, and railings.
Grill or outdoor kitchen exterior. Usually exterior only unless specified. Deep cleaning inside a grill is a distinct service.
Commonly separate: sealing hardscape, rejointing pavers, fire pit interiors, pool or spa surfaces, and any repair.
Hardscape by Material
The material governs the pressure, exactly as it does on a driveway.
Concrete tolerates the most, and a rotary surface cleaner produces the most even result. Stamped or sealed concrete needs reduced pressure so the coating and color layer survive.
Pavers are washed at reduced pressure because high pressure blasts jointing sand out of the gaps, which destabilizes the surface and lets weeds in. Rejointing after washing is often needed and is usually a separate line.
Flagstone and natural stone vary enormously. Sandstone and limestone are soft and porous; slate flakes when worked aggressively. Acidic cleaners etch limestone and travertine permanently, so pH-neutral products are the rule.
Outdoor tile is usually durable but its grout is not, and pressure blows grout out of the joints.
Organic growth -- moss, algae, and the green film in shaded corners -- comes off with an appropriate solution and dwell time rather than pressure. This is the reliable rule across all exterior work: chemistry kills growth, pressure only knocks it back. The same reasoning drives driveway pressure washing and the sequence in the exterior surface cleaning guide.
Furniture, Cushions, and Fabric
Furniture is where most outdoor cleaning damage happens, because people use hardscape methods on it.
Powder-coated aluminum and steel wash with mild soap and water. Abrasives cut through the coating and expose metal to corrosion, so nothing scrubby.
Teak and other hardwoods grey naturally, and that greying is cosmetic. A mild cleaner and a soft brush along the grain is enough. Pressure furs the surface just as it does on decking.
Resin wicker cleans with mild soap and a soft brush. Sun-brittle older wicker cracks under pressure.
Cushions and slings. Check the tag. Removable covers often wash; solution-dyed acrylic fabrics tolerate a dilute cleaner; printed and coated fabrics do not. Anything cleaned needs to dry completely before storage, because damp cushions in a deck box grow mildew fast.
Glass tabletops clean like any glass, finishing with a dry buff so they do not spot.
Outdoor rugs are hosed, brushed, and dried flat, and should never be stored damp.
Mildew on outdoor fabric is common in shaded and humid spots. A dilute cleaner and a soft brush handles surface growth. Fabric with growth that has penetrated the fibers, or that is already sun-degraded and shedding, is at replacement stage rather than cleaning stage.
Shade Structures and Overhead
Overhead elements are the part households most often skip and the part that drops debris onto everything just cleaned.
Pergola beams collect dust, pollen, cobwebs, and often mud nests. Covered patio ceilings hold the same, plus ceiling fan blades that fling it around when switched on.
Awnings and shade sails are washed according to the fabric maker's guidance -- generally a soft brush, mild solution, thorough rinse, and full drying before retracting. Retracting a damp awning is how mildew forms inside the roll.
Umbrellas open, get brushed and washed panel by panel, and dry fully open before closing. The same applies to their storage bags.
Overhead work comes first in the sequence, for the same reason gutters precede siding.
The Seasonal Rhythm
Most households run two main visits and one optional.
Spring opening. The big one. Hardscape cleared of winter debris and treated for growth, furniture brought out and washed, cushions unpacked and checked, shade structures cleaned and inspected, lighting tested. This is also the moment to notice what did not survive winter.
Mid-season reset. Optional, and worth it for heavily used spaces. Hardscape rinsed, furniture wiped, cushions spot-cleaned, and shade structures brushed.
Autumn closing. Everything cleaned before storage, because dirt stored over winter sets. Cushions dried thoroughly and stored somewhere dry, umbrellas dried and covered, furniture covered or moved in, and hardscape cleared so wet leaves do not stain it over the wet season.
The autumn one matters most in wetter climates. Leaves left on a patio all winter leave tannin staining that takes real work to remove in spring.
Decks attached to the same space usually get done in the same visit, using their own low-pressure method, as covered in a deck cleaning service.
Preparation and What to Confirm
Clear personal items, plants in fragile pots, and anything electrical you do not want wet. Say if there are built-in lights, speakers, outlets, or an irrigation head in the area.
Note anything with a specific requirement: a sealed stone, a fabric with a manufacturer's care sheet, a coated tabletop, an antique piece.
Confirm in scope: which surfaces are included, whether furniture and cushions are in or out, whether shade structures are covered, whether the grill is exterior only, and whether sealing or rejointing is offered or referred out. Pricing is quoted after someone sees the space, since a patio with an outdoor kitchen and a pergola is a different job from a bare slab.
FAQ
How often should a patio be cleaned?
Two main visits a year works for most households: a spring opening and an autumn closing, with an optional mid-season reset for heavily used spaces. Shaded patios that grow moss and algae quickly often need more attention, and the autumn clean matters most in wet climates.
Can patio furniture be pressure washed?
Generally no. Pressure cuts through powder coating on metal frames, furs teak and other woods, cracks sun-brittle resin wicker, and can tear fabric slings. Mild soap, a soft brush, and a gentle rinse handle furniture properly, with cushions cleaned according to their care tag.
How do you clean mildew off outdoor cushions?
Check the care tag first, then use a dilute cleaner appropriate to the fabric with a soft brush, rinse thoroughly, and dry completely before storing. Solution-dyed acrylic handles cleaning well; printed and coated fabrics do not. Fabric with growth deep in the fibers is usually at replacement stage.
Will pressure washing damage my pavers?
It can, mainly by blasting jointing sand out of the gaps. That destabilizes the surface and lets weeds establish. Pavers are washed at reduced pressure, and rejointing with polymeric or joint sand afterward is often needed and usually quoted as separate work.
What is the green film on my shaded patio?
Algae, and sometimes moss or lichen alongside it. It comes off with an appropriate cleaning solution and dwell time rather than with pressure, because pressure removes the visible layer while leaving the organism to regrow. Improving airflow and reducing shade slows how fast it returns.
Should the patio be cleaned before or after the house is washed?
After. House washing sends runoff down onto the patio, so hardscape cleaned first would need doing again. The order that works is gutters, then siding, then windows, then ground-level hardscape and outdoor living areas last.
