How to Clean Fake Grass in Devon: Complete Maintenance Guide for Artificial Lawns

Artificial grass has become increasingly popular across Devon, particularly in new-build developments around Cranbrook, Exeter, and Newton Abbot. It offers the appeal of a green lawn without the weekly mowing, but many homeowners discover that fake grass isn’t entirely maintenance-free—especially in Devon’s wet climate.

Without proper cleaning, artificial turf quickly accumulates moss, algae, dirt, and organic debris. Devon’s mild, damp winters and frequent rainfall create ideal conditions for moss growth, whilst coastal areas like Exmouth, Dawlish, and Sidmouth face additional challenges from salt spray and wind-blown sand.

This guide explains how to clean fake grass in Devon effectively, covering routine maintenance, deep cleaning methods, and how to prevent common problems in our regional climate.

Why Artificial Grass Needs Regular Cleaning in Devon

Unlike natural grass that continuously grows and regenerates, artificial turf is a static surface that collects everything that lands on it. In Devon, several factors make regular cleaning essential:

High rainfall: Devon receives significantly more rain than the UK average, particularly from October through March. Water alone won’t clean artificial grass—it simply washes debris into the drainage layer, where it decomposes and creates blockages.

Moss and algae growth: Damp, shaded artificial lawns develop moss and algae rapidly in Devon’s climate. North-facing gardens, areas beneath trees, and turf alongside rendered walls often show green discolouration within 12-18 months of installation.

Organic debris: Falling leaves, blossom, seeds, and bird droppings accumulate on the surface. When wet, this organic matter breaks down into a nutrient-rich layer that encourages moss, creates odours, and stains the fibres.

Drainage problems: Blocked drainage holes lead to standing water, which accelerates deterioration and creates an unpleasant spongy feel underfoot. This is particularly common on artificial lawns installed over clay soils typical of the Exeter and Crediton areas.

Without addressing these issues, even expensive artificial turf begins to look tired and unkempt within two to three years.

Routine Maintenance: Weekly and Monthly Tasks

The key to maintaining pristine artificial grass in Devon is consistent light maintenance rather than infrequent deep cleaning.

Weekly Tasks

Remove loose debris: Use a stiff yard brush, leaf blower, or purpose-made artificial grass rake to clear leaves, twigs, and surface dirt. Pay particular attention after windy weather or following leaf-fall in autumn.

Check drainage: After heavy rain, observe whether water drains away properly. Standing water indicates blocked drainage holes or compacted infill—address this immediately to prevent long-term damage.

Spot-clean stains: Deal with pet waste, bird droppings, or spills as soon as you notice them. Rinse with water and use a mild detergent solution if needed, then rinse thoroughly.

Monthly Tasks

Brush up the pile: Artificial grass fibres flatten over time, particularly in high-traffic areas. Use a stiff brush or power broom to lift the pile and restore its natural appearance. Brush against the direction of the fibres for best results.

Inspect for moss: Check shaded areas, edges near walls, and beneath garden furniture for early signs of moss or algae. Green or brown patches indicate growth that needs immediate treatment.

Clear drainage holes: Artificial grass typically has drainage holes every 10-15cm. Use a narrow brush or pressurised water to clear any blocked holes, ensuring water can drain freely.

These simple routines prevent the build-up that leads to larger problems requiring professional intervention.

Deep Cleaning Methods for Artificial Grass

Even with consistent maintenance, artificial lawns in Devon benefit from thorough deep cleaning once or twice yearly—typically in spring and autumn.

DIY Deep Cleaning Approach

For homeowners comfortable with DIY maintenance, here’s an effective cleaning process:

1. Remove all loose debris: Thoroughly brush or blow the entire area clear of leaves, dirt, and organic matter.

2. Apply cleaning solution: Mix a solution of warm water and either a specialist artificial grass cleaner or a gentle household detergent (avoid anything containing bleach or harsh chemicals). Spray or pour evenly across the surface.

3. Agitate the fibres: Use a stiff brush to work the cleaning solution into the grass, scrubbing in multiple directions. Focus on stained areas and visibly dirty sections.

4. Rinse thoroughly: Use a garden hose to rinse away all cleaning solution. Inadequate rinsing leaves residue that attracts dirt more quickly.

5. Treat moss and algae: For affected areas, apply a moss and algae treatment suitable for artificial surfaces. Follow product instructions carefully, as some treatments can discolour cheaper artificial grass products.

This method works well for small to medium artificial lawns (up to 50-60 square metres) without severe moss or drainage issues.

Professional Pressure Washing

For larger areas, heavily soiled turf, or artificial grass with significant moss growth, professional pressure washing delivers superior results—but requires expertise to avoid damage.

Why pressure washing works: Professional-grade equipment removes deeply embedded dirt, completely eliminates moss and algae, and flushes out blocked drainage holes more effectively than manual cleaning.

The damage risk: Incorrect pressure washing tears artificial grass backing, displaces infill material, and permanently flattens fibres. Many artificial grass manufacturers void warranties if you pressure wash without following specific guidelines.

Professional approach: At Owens Exterior Cleaning, we use carefully controlled pressure (typically 1500-2000 PSI), maintain appropriate nozzle distance, and employ specialist soft washing techniques for delicate turf types. We adjust our method based on the grass quality, age, and condition—premium products tolerate higher pressures than budget installations.

For artificial lawns in coastal locations like Teignmouth or Budleigh Salterton, we also rinse away accumulated salt deposits that stiffen fibres and accelerate UV degradation.

Professional artificial grass cleaning typically costs £80-£150 depending on size and condition, comparable to patio cleaning for a similar area.

Preventing Moss and Algae on Artificial Grass

Prevention is considerably easier than treatment when it comes to moss and algae growth.

Improve Drainage

Most moss problems stem from poor drainage. If water sits on your artificial grass for hours after rain, you’ll inevitably develop moss:

• Check the base: Properly installed artificial grass includes a porous base layer (typically crushed aggregate) that allows water to drain into the soil beneath. If water pools, the base may be inadequate or has become compacted.

• Clear drainage routes: Ensure surface water can escape at the lawn edges. Blocked gulley drains or poorly positioned artificial grass against walls trap water.

• Consider French drains: For artificial lawns in particularly damp locations or over clay soils common around Cullompton and Honiton, adding perimeter drainage may be necessary.

Maximise Sunlight Exposure

Moss rarely thrives in direct sunlight. Where possible:

• Trim overhanging trees and shrubs to increase light penetration
• Consider whether artificial grass is appropriate for heavily shaded areas—natural alternatives like gravel or shade-tolerant ground cover may prove more practical
• Move garden furniture, play equipment, and planters regularly to prevent permanent shading

Apply Preventative Treatments

Specialist moss inhibitors formulated for artificial surfaces provide 6-12 months protection when applied preventatively in early spring. These products are considerably more effective than attempting to kill established moss growth.

What to Avoid When Cleaning Fake Grass

Several common cleaning approaches damage artificial grass or create ongoing problems:

Bleach or harsh chemicals: These discolour artificial grass, break down the latex backing, and harm any plants surrounding your lawn. Always use products specifically approved for artificial turf.

Wire brushes: Metal bristles tear the grass backing and pull out fibres, creating permanent bare patches. Use only plastic-bristled brushes or specialist artificial grass rakes.

Excessive pressure washing: DIY pressure washers often lack pressure regulation, making it easy to exceed safe limits. Damage may not be immediately obvious but significantly reduces turf lifespan.

Ignoring manufacturer guidance: Artificial grass varies enormously in quality and construction. Always follow the specific maintenance instructions provided with your installation, as some products have particular vulnerabilities.

Delaying drainage repairs: Once drainage problems develop, they rapidly worsen. Standing water causes backing deterioration, creates foul odours, and may void your warranty.

When to Call Professional Cleaners

Consider professional help when:

• Moss or algae covers more than 20% of the surface: DIY treatments struggle with extensive growth, and incomplete removal allows rapid regrowth.

• Drainage problems persist: Professional equipment can clear blockages that garden hoses cannot reach, potentially avoiding costly replacement.

• The artificial grass surrounds your property: Artificial lawns around new builds in Cranbrook or contemporary developments often cover large areas including side access and rear gardens—economically challenging for DIY deep cleaning.

• You’re preparing to sell: Clean, well-maintained artificial grass significantly improves kerb appeal and supports higher property valuations.

Artificial Grass Maintenance Across Devon

Devon’s varied climate means maintenance requirements differ by location:

Coastal areas (Exmouth, Dawlish, Budleigh Salterton): More frequent rinsing removes salt spray that stiffens fibres. Wind-blown sand requires weekly brushing.

Inland towns (Crediton, Cullompton, Tiverton): Higher rainfall and less wind means moss develops more readily—prioritise drainage and preventative treatments.

New developments (Cranbrook, Western Exeter): Modern installations typically feature better drainage, but construction dust and clay soil require thorough initial cleaning after installation.

The same climate factors that necessitate regular render cleaning, roof cleaning, and gutter cleaning affect artificial grass—Devon’s wet, mild conditions encourage organic growth on any outdoor surface.

Conclusion: Maintaining Beautiful Artificial Grass Year-Round

Learning how to clean fake grass in Devon properly protects your investment and maintains the pristine appearance that made artificial turf attractive initially. Regular light maintenance—weekly debris removal and monthly pile brushing—prevents most serious problems, whilst annual or bi-annual deep cleaning addresses accumulated dirt and organic matter.

For artificial lawns showing moss growth, drainage issues, or years of neglected maintenance, professional cleaning restores appearance and function whilst avoiding the damage risks of improper DIY pressure washing.
