SPOTON Black SPOT Remover RTU 5L

Does exactly as it advertises. Using neat through pump action sprayer, simply spray over the slabs so it's covered & leave for 2-4hrs then simply rinse off. Slabs look like new again with very little effort & no pressure washing mess. I've been using once a year for past 4yrs & our natural stone slabs look amazing. No pressure washing damage to worry about. Just pick a day when it's not raining 👍 Jobs a gooden 😉

This stuff is just the job when you want to bring you patio back to its original colour. Spray it on carefully over the entire area to be treated and then leave it for a few hours and then if it hasn’t rained you just need to hose the area down to see amazing results.

Having spent quite a lot of time with a powerful jet washer trying to remove black spots from my sandstone patio, I was quite sceptical that this would work. However I was wrong - a remarkable and rapid transformation was achieved with all marks removed. Smells strongly of bleach, so possibly rather expensive?

I bought one of those for my black spot on sandstone slabs (brilliants stuff) didn’t quite finish the job so I got some cheaper stuff, it was useless so I bought another one of yours and did the job straight away well rated thanks

I received this today it was leaking bos was battered so not happy

Very easy to use and fast acting. Not a spot left on the patio that was laid 4 years ago and never been treated before. Will definitely buy this product again.

I used this on my patio as when I pressure washed it there were black mould spots.Left it on for the full four hours but when I rinsed and brushed off the slabs as recommended,Absolutely nothing happened.Still black spots.Waste of time,effort and money.

Used this product for garden patios, excellent cleaner but an expensive way to clean a patio so when I did another patio I jet washed first then went over all the black spot.
