Artificial grass is low maintenance – but it isn’t maintenance free.
If your lawn is used by pets, kids, or sees heavy footfall, bacteria, odours, and organic residue can build up over time. That’s where proper disinfection matters – not just for hygiene, but for keeping the fibres, backing, and drainage system in good condition.
This guide explains how to disinfect artificial grass safely, what products to use (and avoid), and when it’s time to call in a professional deep clean.
💡 Quick Answer: Artificial grass can be disinfected using a pet-safe antibacterial cleaner or diluted vinegar solution, followed by a thorough rinse. For deep sanitation, professional power brushing and enzyme treatments are recommended.

Why Do You Need to Disinfect Artificial Grass?
Artificial grass doesn’t grow bacteria – but organic matter trapped within it can. Over time, things like pet urine, pollen, food spills, algae spores, and general debris settle into the fibres and infill.
If left untreated, this can lead to:
- Persistent odours (especially in warm weather)
- Bacterial build-up in pet areas
- Slippery biofilm forming on the surface
- Blocked drainage and faster wear
Regular disinfection helps keep your lawn hygienic, fresh-smelling, and performing as it should – particularly in gardens used daily by children or dogs.
What Can You Use to Disinfect Artificial Grass?
Not all cleaners are suitable for synthetic turf. The goal is to kill bacteria without damaging the fibres, backing, or glue joints.
| Cleaner Type | Best For | Things to Know |
|---|---|---|
| Pet-safe disinfectant | Routine hygiene, kids & pets | Designed for synthetic fibres, safest long-term option |
| Vinegar & water | Light odours, occasional refresh | Only effective short-term; won’t fix deep contamination |
| Enzyme cleaner | Dog urine & organic smells | Needs dwell time to work properly |
| Bleach / harsh chemicals | ❌ Not recommended | Can damage backing, fibres & glue joints |
Safe Options
- Pet-safe artificial grass disinfectants – Purpose-made and non-corrosive
- White vinegar & water – Mild antibacterial solution for light use
- Enzyme cleaners – Ideal for breaking down pet urine bacteria
What to Avoid
- Bleach or chlorine-based cleaners
- Undiluted household disinfectants
- Solvent or alcohol-based products
- Anything labelled abrasive or corrosive
These products can weaken the latex backing, fade fibres, and shorten the lifespan of the lawn.
Is Artificial Grass Hygienic for Pets & Children?
Yes – when maintained properly.
Artificial grass is non-porous, meaning bacteria sit on the surface rather than soaking in like natural turf. That makes it far easier to clean and disinfect – but only if debris and residue are removed regularly.
If you’ve got dogs using the lawn daily, it’s worth pairing routine rinsing with periodic deep cleaning to fully reset the surface.
How to Disinfect Artificial Grass (Step-by-Step)
Follow this method for safe, effective results:
- Remove debris – Clear leaves, waste, and surface dirt
- Rinse thoroughly – Hose down to flush dust and residue
- Apply disinfectant – Use a sprayer or watering can
- Leave to dwell – Usually 5–10 minutes (check product guidance)
- Rinse again – Remove remaining solution
- Brush fibres upright – Helps airflow and drying
This works well for light-to-moderate use lawns. For neglected or heavily used areas, surface cleaning alone often isn’t enough.
How Often Should Artificial Grass Be Disinfected?
There’s no single rule – it depends on how the lawn is used.
- Light use (no pets): 1–2 times per year
- Children playing regularly: Every few months
- Dogs using the lawn daily: Monthly surface cleaning, plus periodic deep cleaning
If smells return quickly or the surface feels compacted, it’s usually a sign that bacteria or residue has built up below the fibres – not something surface disinfecting can fully resolve.
Common Disinfection Mistakes to Avoid
We see these issues all the time during call-outs:
- Overusing strong chemicals “to be safe”
- Skipping rinsing stages
- Never brushing the fibres afterwards
- Ignoring drainage or compacted infill
These mistakes don’t just reduce hygiene – they can permanently damage the lawn.
When Is Professional Disinfection Worth It?
If your lawn:
- Smells even after cleaning
- Feels compacted or greasy underfoot
- Hasn’t been properly maintained in years
- Is used by multiple dogs or children
…then a professional service is the safest and most effective option.

Disinfecting Artificial Grass: Common Questions
These are some of the most common questions we hear from homeowners before booking a maintenance visit or attempting a deep clean themselves.
Can you disinfect artificial grass with bleach?
No. Bleach can damage the backing, weaken glue joints, and fade fibres. It often causes more long-term problems than it solves.
Will disinfecting artificial grass stop dog urine smells?
Light odours can be reduced, but persistent smells usually sit below the surface. Enzyme treatments or professional deep cleaning are far more effective.
Is it safe to disinfect artificial grass in hot weather?
Yes — but always rinse thoroughly and avoid strong chemicals. Hot conditions can amplify damage if the wrong products are used.
Does rain disinfect artificial grass naturally?
No. Rain helps rinse dust but doesn’t kill bacteria or break down organic residue.
Can artificial grass be over-cleaned?
Yes. Excessive chemical use or aggressive washing can shorten the lifespan of the lawn.
