Results of using the best patio cleaner - Sodium Hypochlorite Before Treatment This cleaner is a chemical compound with the formula NaClO. It is composed of a sodium cation (Na+) and a hypochlorite anion (ClO−); it may also be viewed as the sodium salt of hypochlorous acid. When dissolved in water it is commonly known as bleach or liquid bleach. Sodium hypochlorite is practically and chemically distinct from chlorine. Sodium hypochlorite is frequently used as a disinfectant or a bleaching agent. After Treatment Unfortunately there is no such thing as a weed-free surface. If organic material is allowed to accumulate on a surface it will only be a matter of time before weeds and other plants begin to grow. Weeds grow on paving through the sand joints by using the sand as a base to begin. When using the sodium hypochlorite as a solution for weed control, pay additional care to the joints to ensure success.

Review: The nuclear option for pristine walls and paving (Handle with respect!) - The Bottom Line: FIVE STARS. If your driveway, garden walls, or patio are blighted by deep-seated black spot lichen, stubborn green stains, or thick moss, this industrial-strength chemical is the absolute nuclear option. My provided 'Before and After' photos of my garden wall show the exact results you can expect. This isn't just a basic clean; it is a complete reset. It delivers jaw-dropping, professional-grade results without requiring hours of back-breaking scrubbing. • The Setup: After watching a professional contractor achieve incredible results on my driveway, I asked what he used. His secret weapon was industrial-strength Sodium Hypochlorite, so I immediately ordered this 2 x 5-Litre pack to tackle my weather-beaten garden walls. • The Process & Visual Proof: I applied the chemical completely neat (using a fine mist sprayer) to a heavily stained garden wall and left it to work its magic overnight. The Before image shows the extensive green algae, moss, and dark biological staining that had accumulated over years on a wall I have yet to clean. • The Results: After the neat application and a simple overnight wait, the change was dramatic. The After image shows a wall I have cleaned already. Every trace of thick, embedded moss, deep black spots, and persistent green stains vanished entirely. This after-photo captures the rich, clean, bright colour of the brickwork perfectly, making it look practically brand new. CRITICAL SAFETY WARNING: This product is incredibly potent. Treat it with respect. I strongly advise wearing heavy-duty gloves, protective hat, face mask, goggles, and old clothes. Avoid plants. Work backwards. I used this chemical with the Spear & Jackson Chemical Sprayer (reviewed separately). Review: Very efficient for the money - Items delivered on time and very good and safe packed. I used to clean concrete slabs and tarmac. Both were neglected by the previous owner for 14 years. Full of black and white spots. I had to agitated with a very hard brush and after to rinse with pressure washer. Amazing result, everything looks brand new. I will recommend this company ## Features - POWERFUL PATIO CLEANER – High-strength Sodium Hypochlorite solution, ideal for removing algae, lichen, and stains from patios, driveways, and outdoor surfaces. - EFFECTIVE ALGAE REMOVER – Quickly eliminates green algae, black mold, and lichen from concrete, brick, decking, roof tiles, and fences.
