Biological Oil Stain Remover - Hard Surfaces, Concrete & Blockwork
A powerful, environmentally friendly, non-toxic biological oil cleaner and degreaser
OT8 rapidly removes and digests oil contamination from porous surfaces such as block work, paving stones, concrete, driveways, garage floors and forecourts - OT8 outperforms conventional oil stain removers by removing not just the spill but the oil stain too!
Effective & powerful
- Removes stains caused by leaks, spills, splashes or drips of hydrocarbon liquids including oil, diesel and power steering fluid - OT8 is even effective in removing old, embedded stains
- Non-toxic, VOC free and with no potential for bioaccumulation
Safe to use
- Non-flammable and with low hazard profile - requires no special PPE or spill control equipment
Quick and easy to use
- Ready to use formula with no mixing or preparation needed - just shake, pour on, brush in, leave for 20 minutes then rinse with water. It's that simple!
- Naturally digests oil contamination into harmless CO2 and water
- Naturally breaks down in the environment, leaving no soil residue and with no hazard to grass and plants
Where to Use
- Rapidly removes and digests oil stains from surfaces such as block work, paving stones, concrete, forecourts, garage floors, driveways and equipment.
How to Use
OT8 is simple to use and lifts oil stains from most porous surfaces.
- Shake container well before use (to put bacteria into suspension).
- Water wet the oil stain before applying OT8.
- Brush into the stain using a soft brush until OT8 changes colour from off-white to brown.
- Leave for 20 minutes and water rinse.
- Approximately 1 litre of OT8 treats 1 square metre.
If using OT8 KIT
- After rinsing, apply Spill Gel to absorb free oil and prevent spills reaching surface drains.
- Sweep up and dispose of according to local regulations. Rinse clean.

- OT8 is a biological solution that uses harmless bacteria to remove oil stains from porous surfaces.
- For best results or for when using on larger stains, cover the treated area with polythene sheeting − ideally making a tent − and keep in place for up to a week. Ensure the area remains damp, but not flooded. Doing this provides a warm and damp environment, giving the bacteria used in OT8 the best conditions to grow and digest the oil into carbon dioxide and water.
- On old, weathered and ingrained oil stains, the oil stain may “re-appear”. This is because the bacteria in OT8 keep working after application to bring the ingrained oil stain to the surface. Some types of concrete are more easily treated than others and for optimum stain removal it may be necessary for OT8 to be applied more than once, over an extended period of time.
- OT8 is not suitable for use on Wood oils.
- OT8 is not suitable for oil stains on Tarmac − please use Bio TA.
OT8's unique formula works in two ways:
- OT8 penetrates the oil and lifts stains from hard surfaces
- The specially selected bacteria in OT8 naturally digest the remaining oil to completely remove the stain
Our combination of eco-friendly formulation and high performance cleaning makes OT8 the perfect all-purpose oil stain removal solution - OT8 gives you industrial strength cleaning results without the hazards or toxic side effects of others products!

While the food source − ie ‘oil stain’ − is present, the bacteria keep on working and continue to do so until it’s all gone!
For the biological cleaning of oil stains to be effective, it requires:
- Food source for the bacteria to digest, i.e. the 'oil stain'
- Warm conditions
- Moist conditions
- The correct bacteria
On the basis that the first four conditions are in place, the bacteria selected for use in our products will digest oil stains - from light oils to heavy crude.
The bacteria used in our products are Euro Type 1 (safe for long term laboratory application and safe for long term general public exposure).
Please note: speed of oil digestion is temperature dependent. At an ambient temperature of 15°C, we would expect the full digestion process to take 4-6 weeks. For every 10°C above or below this temperature, the speed of digestion increase or decrease by 50% i.e. at an ambient temperature of 25°C digestion time of 2-3 weeks would be typical.

I have just used OT8 on an 8 month diesel spill and usual collection of engine oil stains on my block paved drive and am absolutely amazed at the results. After an hour's light labour (two small applications) all the stains are virtually gone and peace and harmony is once again restored to the household.
Reading feedback on various sites prior to the purchase of OT8 I am of the opinion that most if not all other products would not have given such outstanding results for such a small amount of work … I would have no hesitation in recommending it without reservation.
Thank you for one of the very few products available today that actually “does what it says on
