What You'll Need Before You Start
Knowing how to clean oil stains from block paving step by step starts with the right kit. Oil soaks into joints and surface, so speed matters:
Rubber gloves and eye protection
An oil stain remover or heavy-duty degreaser
A stiff brush and a scrubbing brush
Warm water and a bucket
Absorbent cloths or paper towels
Kiln-dried jointing sand for topping up joints afterwards
Fresh spills lift far more easily than old, set-in marks, so act promptly.

Step-by-Step: How to Clean Oil Stains from Block Paving
The best way to clean oil stains from block paving step by step is to blot, treat, scrub and rinse, then re-sand the joints.
Blot the spill. Press cloths onto the stain to soak up wet oil. Do not rub it in.
Apply a degreaser. Cover the stain and leave it to dwell as the label advises.
Scrub the surface. Work the product into the paving and joints with a stiff brush.
Rinse and check. Wash away residue and inspect. Repeat if the mark remains.
Top up the joints. Once dry, brush in kiln-dried jointing sand where it has washed out.
A common mistake is reaching straight for a pressure washer: blasting oil can drive it deeper and spread the stain. Gentle, repeated treatment works better.
Oil often collects in open joints, which can also hold debris and support weeds. Cleaning and re-sanding may reduce this but cannot guarantee permanent prevention.
Watch Out Never mix cleaning chemicals, and never pour waste water down a surface water drain. Check the label and follow local guidance for disposal.

Frequently Asked Questions
What is the best way to remove oil from block paving?
Blot up as much oil as possible, then apply a suitable degreaser or washing-up liquid solution and work it into the stain with a stiff brush. Rinse thoroughly and repeat if needed. Older, soaked-in oil stains on block paving may need professional treatment. A biocidal pretreatment for driveways and professional cleaning can also lift the surrounding grime that makes oil marks look worse.
Will washing-up liquid remove oil stains from a driveway?
Washing-up liquid can lift fresh, light oil marks from block paving if you act quickly. Mix it with warm water, scrub the stain and rinse well. It struggles with older stains that have soaked into the sand and surface. For stubborn marks, professional block paving cleaning in South Croydon and the surrounding areas may be the more reliable option.
Does oil permanently stain block paving?
Not always. Fresh oil that is blotted and treated quickly often lifts well. Oil that has soaked deep into the blocks or the jointing sand can leave a lasting mark, and some staining may remain even after professional cleaning. Following cleaning with kiln-dried sand replacement and sealing, where suitable, can help reduce the likelihood of future oil soaking in.
