Produced in the UK, the formulations target all the usual problems of dirt, moss, algae, lichen and mould on outdoor surfaces. When buying partner items like this one, your contract of sale will be with our Range Plus Partner instead of us. In one five-litre bottle of product, you’ll get around 25 litres worth of cleaner – it’s one of many patio detergents you’ll need to dilute. With this, you should get coverage of up to 250 square metres depending on porosity. By working with a variety of trusted Range Plus Partners, we’re able to offer our customers a wider selection of products. As there are active chemical ingredients, you will need to make sure that you exercise safety. Therefore, always ensure that you put on heavy-duty gloves and, where possible, wear safety goggles, too. You’ll also want to make sure you keep your kids and pets out of the way until the product is dry and, like many spray & leave cleaning products, don’t use near aquatic life.

Based on the Spray and Leave average, you will likely start seeing results on tough stains and green growth within four to five days. That’s not much to ask if your paving slabs are caked in the stuff.Spray and Leave sinks down deep into nuisance growths, meaning all you should really need is a stiff broom to get rid of the worst stuff afterwards. However, we’d always advise you to look for a specialist cleaning solution for natural stone paving. There’s no need to break out a pressure washer or give your paving slabs a jet wash after you spray this on – hence Spray and Leave. There is definitely a market for patio cleaning solutions that clean deep without a pressure washer now, and while Spray and Leave seems to be one of the more expensive in this line, it does still get a patio clean without you needing to plug in any fancy equipment.
