Step-by-step instructions on how to clean block paving without using a pressure washer
1. Remove all pots and patio furniture that is sat on the block paving
Before you begin to clean your block paving you first need to remove any plant-pots or patio furniture that is sat on the paving. This stops any dirty marks being left on the paving if you decide to move the pots or furniture at a later date.
2. Brush the surface of the block paving to remove any loose dirt
Brush the block paving surface with a stiff broom to remove all loose material. Take particular attention to corners and difficult to reach areas like behind drainpipes and in water drains. Or you could cheat and use a leaf blower. Although if you decide to use a leaf blower be careful to remove all loose stones and large debris first. These can become projectiles when using a leaf blower to clean your paving causing damage if they hit glass windows or cars. Try to not remove too much sand when brushing or blowing your block paving clean.
3. Remove any weeds and moss from the block paving
You may already know, or it could become more apparent once you have brushed the surface of the block paving that you find you’re paving needs a weed killer applied before you clean your paving.
If this is the case, apply the weed killer according to manufactures instructions. Always allow a few dry days for your weeds and moss to completely die before you clean your block paving. You can tell the weed killer has worked because moss will turn brown and the weeds will wilt. When moss dies it turns brown and becomes surprisingly loose from the surface of the paving joints making it far easier to clean block paving.
Then remove weeds when the weeds have died with a hard scraping tool or by hand
- If you are going to use a pressure washer to remove the weeds please read our guide first. Use a jet washer cautiously to remove weeds. You can damage the structure of your paving when using a jet washer to remove weeds if not done correctly. Jointing sand is easily removed with a power washer, this is not good as the block paving bricks need the kiln dried sand to keep the individual paving bricks solid and locked together. If this is removed then the strength of the paving is weakened. If you have decided to use a power washer to clean your block paving please see our recommendations here on how to clean paving with a jet washer here.
4. Treat oil and grease stains with an oil remover if necessary
If necessary, treat any areas of paving blocks that have oil stains on them separately with a suitable oil and grease removing cleaner. If the oil stain on the block paving is only light then try applying neat washing up liquid. After applying, scrub vigorously then rinse with hot soapy water whilst still scrubbing. This method of removing oil from your paving could remove or disguise the oil stained paving sufficiently for you not to notice the oil stain.
Often if you’re paving is very dirty, oil stains in your block paving do not become apparent until you have cleaned your paving. In which case, you may need to repeat the cleaning process after treating any oil stain. Do this after you are confident that you have removed the oil stain from the surface of the pavers.
5. Wash the whole surface with soapy water or specialist block paving cleaner
Do you need to apply a paving cleaner? This depends on how dirty your paving has become. If the dirt is light, you can simply apply a solution of weak soapy water to the block paved surface to lift the dirt from the surface. Or you could apply a biodegradable recommended paving cleaning product that does not require the use of a pressure washer to clean the block paving or try using bleach. As well as cleaning your paving, a specialist cleaner or using a cleaner such as bleach will kill the weeds at the same time as cleaning the dirt from the surface of your paving.
6. Gently scrub the water or cleaner into the surface of your block paving
Assuming your paving has only slight dirt, once you have applied the soapy water or cleaning product onto the surface of the block paving gently scrub with a stiff broom to work the liquid into the surface and between the joints. This helps remove deep ingrained dirt.
You could use a pressure or jet washer to brush and scrub the surface of your block pavers. These are called rotating cleaning brushes and are ideal for cleaning if your block paved surface has deep-down ingrained dirt that could be difficult to remove. You can find more information and reviews on the different kinds of rotating head cleaners for pressure washers here
7. Rinse the block paving with clean water
Once the soapy water or cleaner has been brushed into the surface finish by rinsing the block paving surface with plenty of clean water. This removes the dirty water or cleaner and any leftover dirt.
If you are going to be using a power washer to rinse the block paving after the cleaner has been applied to the surface of the pavers please read our guide here first.
8. Finish by replacing any lost kiln dried joint sand when you’re paving has dried
After the block paving has had time to dry replace any lost sand with paving joint sand to the top of the joints. Simply brush into the joints on a dry day. Keep applying joint sand when necessary.
Other recommendation we have on how to clean block paving keeping it weed free
It is recommended that you should apply a suitable weed killer to the block paving (prevention is better than cure when it comes to weeds) at periodic times throughout the months of the year after you have cleaned your block paving to stop the further growth of moss, weeds and algae blooms.
Weed killers for patios and driveway block paving are readily available in all kinds of formulas. You should always try to use an organic and non toxic solution that is safe to use with pets, ponds, children and wildlife.
Apply a moss and algae killer on a dry day when the paving is dry and no rain is forecast.
