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. Applications Swimming Pools Patio Cleaner Bleaching Agent Water Purification Odour Removal Lab Use Specification and Material Safety Data Sheet are available upon request. Packaging may be 4 x 5 Litre depending on stocking level. Important Notes: - This product is not for use on lawns, flowerbeds, vegetable plots or around trees and shrubs. - Keep people and pets away from the treated area for 2 days. Storage Requirements - Always store this product in a cool dry (below 24 deg C) location that is away from children and animals. Warm and exposed to sunlight conditions will have an adverse reaction to the product as the chlorine will vent naturally. Guidance for Using as Pool Chlorine Sodium Hypochlorite 15% is used for the routine control of bacteria and algae in swimming pools. For effective treatment ensure that the chlorine levels of the water are a level of 2-3mg/l (ppm). The levels must be maintained above 1.5mg/l (ppm) as a minimum.

Review: Ideal cleaner for Patios and Block Paving - I use this cleaner mainly for my block paving driveway that is prone to weeds and moss growing between the blocks. It is best diluted 1 part cleaner to 4 parts water, so I use a litre of the hypochlorite and 4 litres of hot water in a watering can and carefully cover the entire area to be treated. Be aware this is a strongly corrosive product so wear protective clothing to avoid splashing on your skin, especially hands and eyes. It acts as both a herbicide and cleaner. Your paving will be cleaner and clearer after use - normally a few days later. The great thing about sodium hypochlorite is it degrades to salt so should not harm the environment in the same way as some other chemicals. It also works really well on cement paving slabs, porous stone window sills and curbs. Also be aware when pouring it can splash a little when the container is quite full, so pour carefully or use a funnel. Overall this is a great product and most of the time beats harsh pressure washing.
Review: Worth everybienny. - Excellent product, good value and made a huge difference to finish on the patio and oaths.

## Questions & Answers

**Q: Does this product leave any residual smell?**
A: Couldn’t smell anything after two days. The more you rinse it of, then the faster the odour will go.

**Q: Do you need to pressure wash off or just hose it down**
A: Probably quicker with a pressure washer, but you don’t have to. Hope this helps. 👍

**Q: Will it rot  weed control fabric under pavers**
A: I would say yes, rather than no. It’s pretty strong stuff and works very well. If you’re unsure, place a small piece of fabric in the diluted solution and see what happens. Maybe leave it for a week. Good luck.

**Q: Hi can this be used on resin bound Aggregate**
A: Try a low solution about 10% on test area keep it wet leave 30 mins rince off. Gently step up the solution to remove moss algea. The colour can fade on these so if may need recolouring
