Rapid Action Black Spot Remover Patio Cleaner for Stone, Block Paving, Concrete, Paths, Steps and More 5L

Have just used this to get rid of black spots on my patio paving slabs. I'd previously pressure washed the patio but there were many areas with black spots. I applied this with a garden pressure sprayer, left it for 5-6 hours then washed it down. The results were really good - patio slabs all very clean and no visible black spots (as shown in photo). Will certainly use this again in the future.

Excellent product. Got rid of the black spot and my driveway and patio look great.

I used product decanted into a pressurised spray bottle . Results were really good, quite impressed. The patio has been down over 12 years and every year or so i jet wash it. But the build up of black spots is horrendous. Having read the reviews I chose to buy some. Sprayed it , agitated it with a stiff broom, left for 2 hours then washed off with a hosepipe. The results were good though not perfect. It's not badly priced but to get rid of all of the black spot I'm probably faced with having to buy another 5l can. My photos are slabs that havent been treated and the circle kits that have been treated. I would definitely recommend.

This product is brilliant. It does what it says. It started working immediately. My block paving is like new, also my slabs and brick wall. So easy to use .Just spray n leave.

Was really happy with the results, our patio never looked better.Very easy to use would highly recommend!No more black spots.

Not quite as good as more expensive products on the market but you get what you pay for, I suppose.Removes the blackspot well but doesn’t restore the stone to the same level as other - more expensive- products.

Slabs were covered in black spot, and didn't think this product would really shift it, but one coat only and rinse it off.....it's magic ! Very pleased......doesn't do 40 square metres though, maybe 10 or so ? But ordered some more, it's worth it.

My patio hadn’t been properly cleaned for a few years. This is the first time I’ve used Jarder spot remover but it won’t be the last. I sprayed some of the worst patio stones and left it overnight washed it off the next morning and couldn’t believe the difference as can be seen in the attached pictures. I will now be completely doing the rest of my patio and block paving driveway. Excellent results at a very reasonable price.
