Tarmac is a strong and durable surface. It is quick, easy to use, and is low-cost to maintain. It helps make the driveway water-resistant and slip-resistant. A tarmac driveway provides a safe and attractive surface for cars to park on. Tarmac is made up of crushed stone and tar and is made to last.  It can be used on any driveway. Over time, tarmac can become stained and dirty. In order to keep it looking its best, it is important to know how to clean a tarmac driveway.

What Is The Best Way To Clean A Tarmac Driveway?

Before you start

Sweep away any debris, dust, leaves, and rubbish. Move any plant pots or bins so that your driveway is completely clear. Make sure you are wearing appropriate protection, such as gloves for your hands.

First Steps:

When cleaning a tarmac drive, the first thing you want to do is make sure that you can clean all the petrol and diesel. To do so, use a degreaser solution to loosen it from the drive. However, make sure the solution label specifies it can be used on tarmac. Some can be damaging and corrosive. You also need to check how long to leave it on the drive to be effective. They can be powerful chemicals, so make sure you read the instructions thoroughly. You can also use washing-up liquid or another mild detergent to help dissolve any oil that has spilt onto your tarmac. This allows you to fight against stubborn and difficult-to-remove stains.

Next Steps:

Once you have removed all of the oil wash the drive. Use a power washer at a low setting to avoid causing any damage. If you do not have a pressure washer, use a garden hose on its lowest setting and hold it about 30cm away from the surface of your drive. Slowly move the hose across the drive, overlapping each stroke by around 5cm to ensure you cover the whole area.

After washing, allow your driveway to dry completely. Once dry, check the drive for any moss or algae growth and remove it. You can do this by using a stiff brush or a garden hose on its highest setting. Be sure to also check the edges of your drive as this is where moss and algae often grow.

Once you have removed all the moss and algae, you will need to treat the drive. This will help prevent any further growth. You can buy a ready-to-use moss and algae treatment from most garden centres or DIY stores. Make sure you follow the manufacturer’s instructions on how to apply it.


After treating the driveway, give it a final wash with a power washer or garden hose on its lowest setting. Allow the drive to dry completely before parking your car on it or walking on it. You can maintain it longer by applying a sealant.

Cleaning a tarmac driveway is important to keep it looking its best and to prevent any stains or marks. By following these simple steps, you can ensure your drive is always clean and inviting.

Does Pressure Washing Damage Tarmac?

If you are pressure washing tarmac with the correct equipment in the correct way, it should not damage your driveway. However, if you use the wrong kind of jet and too much force, it can damage the tarmac and dislodge small pieces. Continuing to pressure wash can end up stripping away the top layer, leaving behind a weak, less resilient second layer.

Following the instructions above and ensuring you hold your washer around 15 inches off the ground will ensure you get the best clean and cause little damage to your driveway.

Can You Clean Tarmac With Bleach?

Bleach can be used to kill any weeds or moss growing through the small gaps in your tarmac drive. This solution may seem like an easy fix to cleaning your drive. However, harsh chemicals that are either caustic or acidic should be avoided as much as possible. This will damage your tarmac drive, and the runoff can kill any nearby plants, and even small animals and pets.

How Can I Make My Tarmac Drive Black Again?

Exposure to high temperatures in the summer can cause your tarmac to fade and soften, becoming more vulnerable to further damage.

To make your tarmac drive black and just like new again, you need to use a restorer. This will help recolour and revive your driveway. Not only does it clear up the color, but it will also help to add further resistance to any future deterioration. Once you have cleaned your driveway, seal any cracks with bitumen paint, and then use a roller to apply a restorer. The restorer will help protect the driveway from the weather, any oil or petrol spills, and any growing weeds. It will also leave your driveway looking good as new.
