BIO-K20 (AG) Artificial Grass

(Artificial Grass Cleaner)


Bio-K20 (AG) is one of the most powerful and effective products on the market for the complete eradication of dog, cat and other pet urine odours on artificial grass, astro turf and other artificial turf surfaces.

This product can also be used on most other external surfaces, so it is ideal for patios, decking areas, driveways and most other areas which your pet uses as their toilet.

Dog Pee Posts have become quite popular in recent times in an effort to encourage pets to urinate in a particular area of the garden. Bio-K20 (AG) is the perfect solution to use in these particularly troublesome patches as the most effective answer to the dog urine odours.  


As more and more of us are taking advantage of outdoor living and making use of the benefits of artificial grass and turf, there is an increasing demand for high quality and effective enzyme products for dealing with pet urine odours on these types of surfaces.

Bio-K20 (AG) removes the smell of pet urine from
artificial grass, turf and wooden decking surfaces.

Bio-K20 (AG) is the scientific answer to the problems associated with all pet wee smells and stains. Designed specifically to be used outdoors on artificial grass and turf surfaces, wooden decking and other outdoor hard surfaces.

Highly effective in dealing with dog, cat and most other forms of animal urine and faeces contamination.

BIO-K20 (AG) is a super strength concentrate and should be diluted with water prior to use.



Bio-K20 (AG) is a super strength biological formulation containing a complex blend of enzymes and bacteria designed to attack bacterial waste and urine and remove it by digestive action, converting the waste, the main breeding ground for harmful bacteria, smells, etc; into simple sugars, non-harmful gases and water. The enzymes in Bio-K20 (AG) digest the urine, uric acid and stains within the fibres of your artificial grass and the veins in wood and continue to be active until all of the contamination has been completely and effectively removed.


Ecologically and Environmentally friendly
Biodegradable, safe under CHIP/COSHH
User friendly
Non-acidic and non-caustic
No astringent odour & non staining
Digests the cause of bad odours
Strongest formulation and most effective
Harmless to animals and humans
Deep layer penetration



How To Apply
if the area to be treated contains pet faeces, remove these prior to treatment. Bio-K20 (AG) should then be diluted before use. Dilution rates depend on the degree of contamination, usually between 1 : 5 and 1 : 10. Mix 1 part product with between 5 and 10 parts warm water and apply liberally by watering can or sprayer to the whole area. It is important to apply the solution to the entire area (not just to patches) to ensure that the enzymes come into direct contact with all areas of contamination. If pets have been visiting the area regularly over a lengthy period, we would recommend using a stronger dilution as an initial treatment. Coverage will very much depend on the degree of contamination but generally 1 litre of concentrate should treat around 20 – 40 sq.mtrs. Allow sufficient time for the whole area to dry out naturally and for the enzymes to become fully active, which can be around 48 hours from the time of application. This initial process can be repeated if necessary until all of the odours and stains have been completely digested. Always allow at least 3 – 4 days between applications.

Avoid using disinfectants and bleaches on surfaces treated with Bio-K20 (AG). Never mix with other chemicals or fragrances.

If pets are to continue to use the area then obviously further applications will be necessary but we would suggest that the dilution rate can then be increased up to 1 part product to 8 – 10 parts water. Ideally a regular plan or schedule of treatment should be maintained to ensure that urine odours are kept under control.

The product is also ideally suited for use on hard surfaces and can be used to remove stains and pet urine odours from wooden decking, concrete, paving and other external hard flooring.

Bio-K20 (AG) can be used throughout the year but if possible try to choose a dry period when applying. Heavy rain will obviously dilute the product further and reduce its effectiveness.


The microbial strains in Bio-K20 (AG) are all naturally occurring and have been classified as being harmless to humans and animals.
Bio-K20 (AG) is a high quality speciality product manufactured to strict specifications and currently supplied to vets surgeries, kennels, catteries, police and prison service dog handlers and pet grooming businesses throughout the UK as an effective and proven solution to the the problem of removing pet urine odours & stains.

Developed by our chemists working together with leading British universities in this field of biological products. This product is just one from our range of speciality biological products all of which are very safe and kind to the environment. They are each designed to break down and digest different forms of natural waste, reducing them to simple harmless entities while leaving treated areas clean and odour-free. Within an individual product there are various forms of enzymes; each of them performing different tasks to ensure the most efficient performance. Being a superior alternative to standard chemicals, our biological cleaning agents remove the cause of the problem rather than trying to mask it. The need for further treatment is thus reduced, saving time and money in the process.

As a responsible business we try to always give our customers accurate information and the safety of our customers is always given the highest priority.

Does exactly what it says on the label

Having tried several other dog odour control/artificial grass cleaners, we finally found this one and it has massively improved enjoyment of the garden all year round. Our artificial lawn was laid 4 years ago and our 2 cocker spaniel girls have kept it regularly and frequently "watered" since then. Other deodourisers only masked the smell of dog urine for a short period of time, in some cases only days. Whereas the Bio-K20 seemed to magic the scent away for weeks, if not months after each application, even through the middle of Summer. Highly recommend this to anyone with an artificial lawn and dogs.

This is a great product but it took some time to work. The smell was awful straight after we applied the BIO-K20 but thankfully we applied it at night (as advised by TMC staff). I do have 2 large dogs who had been urinating on the grass for some time so it took a fair few weeks to get rid of the existing smell. I now use this on a weekly basis which seems to work for me.

This is by far the best artificial lawn cleaner/odour eliminator I have come across. I used so many different ones that claim to eliminate urine smells but they never worked. We already had an existing problem so we knew it wasn't going to be an overnight process but with regular treatment, we now have an odour free lawn.

We had our artificial grass put down last year which our little westie uses a few times a day for his toilet. We watered the grass every day which is what we were advised by the contractor and have never had any issues. However, the summer hit and the smell outside was horrendous. We spoke with a lady on the phone about our situation and they recommended to apply this product every few days to initially get on top of the smells. We didn't really see any improvement for a few weeks but after this period the change was unbelievable. The garden is now a smell free zone. Very happy customer.
