Kärcher 62957650 3-in-1 Stone Plug and Clean - Black

The key thing is to follow the instructions, as different cleaners will work in different ways. Some work better if applied to a wet or dry surface, and may need rinsing off a few hours after application. Others use a ‘wet and forget’ approach, where you just apply the cleaner then leave it on to do its work. Are there different types of patio cleaner for different problems?You do need a little patience with this one. While the effect varies, you might find that, for the first day or two, nothing much seems to have changed. However, as time goes on, all that slippery algae and stubborn mould will disappear, and the longer you leave it, the better it gets. And while it seems expensive for what it is, this one bottle of concentrate makes 30 litres of spray, so you won’t need any more for a while unless you’ve got vast, palatial gardens. It’s the most effective of the spray-and-go cleaners.
