Cleaning a patio around a swimming pool without making it slippery comes down to fully removing the algae and biofilm causing the problem — not just washing the surface.
Basic pressure washing often only removes visible dirt, leaving behind a thin layer of contamination that becomes extremely slippery when wet.
A proper professional clean involves:
- Breaking down and removing algae and biofilm at the source
- Using controlled pressure washing, DOFF steam cleaning for more delicate surfaces, or targeted professional treatments where required
- Thoroughly rinsing and clearing all residues from the paving
In many cases, DOFF steam cleaning is used on natural stone patios, as it delivers high-temperature cleaning at low pressure, helping to remove contamination safely without damaging the surface.
Where needed, specialist treatments are applied to break down organic growth safely, allowing for a deeper clean and helping to reduce the likelihood of rapid regrowth.
This process restores the natural texture of the stone, improving grip underfoot and making the surface significantly safer to use around the pool.
