Pro-Kleen Ultimate Black Spot Remover and Destroyer for Patio, Stone, Block Paving, Indian Sandstone, and more. Easy to Use Fluid that Powers Through Stubborn Dirt & Grime (5 Litres)

Product Information

It’s best to use this product when there’s no rain forecast for a couple of days – just to ensure it has time to fully work. This could prove difficult if you’re wanting to clean your patio in winter. To use, simply apply to the affected area using a pump sprayer or a watering can – there’s no mixing required.

The concentrated formula is highly effective but still very safe to use. Kids and pets should still be kept away until the area is dry however, and you’ll still need to take extra care when handling this solution, to avoid harm to your eyes and skin. You can use it to clean up almost any stone or concrete surface, including patios, drives, flagstones, pathways, paving slabs, resin, and sandstone. In just a few hours, it breaks down any dirt that’s on the surface, leaving your garden looking truly spotless! Amazing Coverage You can prolong the lifespan of your patio and keep it looking better for longer by sealing it. Sealing protects it against rain, oil and grease stains, and other spills. Our Patio Seal is what’s known as an impregnating sealer. Once applied, it’s partially absorbed by the stone, creating an invisible barrier that protects it against the weather. It also helps prevent general wear and tear, so it’ll look its best for much longer. How Often Should I Seal My Patio? This product can also be used on fencing, sheds, caravans, conservatories and uPVC windows, so you don’t have to buy separate products for all these different jobs! It’s a very powerful option, easily removing all sorts of grub and grime. Another of this product’s features is that it doesn’t specify sunny conditions to be essential for application. Although results might not be as effective, you can also clean your patio with this product in the winter if you want to.

Safe for Most Stone Surfaces

It doesn’t require rinsing off, scrubbing or pressure washing, although if you have lots of moss then you may still need to gently remove it with a brush. Once treated, this solution produces an invisible barrier which can help to prevent regrowth for up to 6 months. It doesn’t contain any acid or bleach, so won’t damage your surfaces. It’s also safe to use around children and pets, although they should still be kept off the treated area until it has dried. The cleaning fluid needs to be left on the surface for at least 2 hours, during that time the surface must not be allowed to dry out. In hot dry conditions it may be necessary to apply a mist spray with additional cleaning fluid to prevent the paving from drying. Work the area(s) of staining with a brush, if necessary, but ensure the surface remains moist at all times. It does need diluting, and because of the high strength, it’s important that the concentrated product doesn’t touch your skin. In fact, I’d recommend wearing protective gear and clothes you don’t really care about – even a small splash of this product will discolour your trousers! To use this patio cleaner, dilute 1-part cleaner to 4-parts water, then apply with a garden sprayer or watering can. There’s no need for scrubbing or rinsing (which is always excellent news!).

Leave on the affected surface for 2-4 hours. It will start to fizz as it works – don’t worry, this is normal! Keep pets and young children away from the area during this time. Algon does also make a ready-to-use version of this product which has a sprayer. It’s not as cost effective but it is useful if you just have a small area to spray and don’t want to invest in a garden sprayer. Despite living in the unpredictable UK climate, we still spend a lot of time in the garden – even when the weather isn’t great!

Mix the Ultima-Plus XP with water. Our recommended ratio is 4 parts water for every 1-part Ultima-Plus XP.

Different brands require different levels of dilution, but it’s not difficult to measure out the formula into a separate container. The formula contains no bleach or acid, so there’s no need to worry about anything becoming discoloured or damaged. Safe Formula Leave the area for 2-4 hours. Keep pets and children away during this time. The solution will start to fizz as it works – this is normal and nothing to worry about.

Users have also reported needing to use a wrench to open the lid, as it’s quite difficult to get into. This might be an important consideration if you have mobility issues in your hands.
