Homefront Rapid Acting Black Spot Remover - Removes Black Spots Quickly and Easily For use on Patios, Driveways, Paving & More - Easy to Use Fluid (5 Litres)

This product is amazing! I was surprised at the results. It left the slabs very clean. Some stubborn spots needs more than one treatment. If you have a big patio like mine,you will need about 25 litres of the product. At least! To cover front and back garden slabs. Also make sure you are well protected. Use goggles,mask,gloves,tall boots and something to wear over your clothes. Please! This is a very strong bleach stuff. Allergic people stay away from it. I recommend the product.

I was planning to post a poor review after first using the product as after leaving it for 4 hours and rinsing it off, I was disappointed in the result. However, seemed to continue to work overnight and the next morning I surprised to see an improvement. I put on another treatment and rinsed again and this has produced excellent results. My advice is don't expect it to produce an immediate improvement.

It did a good job of removing the black spots, 2 applications required in dense areas.

Excellent for removing all that grime. But I found I had to use more than double the suggested dosage to fully clear the area.

Don't usually do reviews but so impressed with this! Dirty path with heavy black spot along edge where grass had grown over. Put this on using a pump sprayer, left for 2 hours, then used low pressure washer and the results are amazing. Almost as good as when it was laid. Just don't get it on your clothes! 😂

Effective spot remover, even diluted ~1 to 1 with softened tap water and on patio slabs not previously treated for about 5 years (apart from pressure washing). Applied with garden sprayer and kept moist: most spots cleared in 2-3 hours. BUT - bleach based (sodium hypochlorite) so care needed.

It didn’t work

Did the job, had to do some areas twice but on the whole a good product
