Render Cleaner Softwash Solution - Acid Free Render & Masonry Cleaner (5 Litre)

Absolutely amazing stuff probably the best render cleaner I’ve used tried many others but none have been a patch on this one and perfect to clean the render before painting

Great product, easy to use and extremely effective. Highly recommend.

Our house is covered with a silicon-based white render. This product cleans it really easily. The render is about 4 years old and was starting to develop various green and black algae patches. I used the recommended 5:1 mixture leaving it for 15 minutes and the render cleaned very well, much better than I expected. I also used the product to clean some of our block paved driveway which was going green, the drive cleaned up a treat. The only reason for 4 stars rather than 5 is the price, it is rather expensive.

Really works on green mouldy marks and water run marks. Pleasantly surprised. Definitely recommend

Awsome stuff easy to use. Beware you will need a good face mask and goggles strong stuff

i don't know if i'm not using it right but it hasn't worked for me . it is easy to apply but that's all i can say

Works well, I used 1to1, and the front of my house looks great now, as per my photo you can see the difference, basically sprayed on and left then hosed off recommended

I'm utterly blown away by this stuff - it's stunning. I bought 5l, and with only one full garden sprayer of mixed solution I cleaned one entire side of our house. On one face of the house, there' is (or was!) a pattern of lichen or some other dark marking which matched the blockwork underneath (but weirdly the lichen didn't grow on the render above the mortar between the blocks). So we have this strange blockwork pattern of lichen - it was a bit of an eyesore. My plan was to clean, prep and repaint that bit of the house. To that end I had scaffold set up, and bought some of this stuff (plus the sealant solution from the same company) and I've been up there this morning applying this stuff. It's quite astonishing. Spraying the stuff, the lichen (or whatever it was) starts going yellowy-orange, and as I work my way down from the top of the gable I can see this stuff running down the wall, and leaving clean streaks as it goes. After fully spraying the wall everything _already_ looked cleaner, but after 15 mins I was back up there with a hosepipe to wash everything away. And it literally ALL* washed away (*there was one single stubborn bit - I think maybe I missed it on the first pass, but I'm writing this review after respraying that one section - I've got 15 mins before I get back up there with a hosepipe to rinse). In our particular case, the mortar needs touching up in places - so I'm going to need to repaint anyway; so I definitely needed scaffold this time round. But after using this stuff (and then using the sealer, and then repainting) I don't reckon I'd need scaffold again. Based on what I've seen so far today, then I can just use this to clean the paintwork and I'd not need to repaint. All I need is a long enough extension on my garden sprayer (long enough so I can mist the highest parts of the house - possibly from a ladder) then I wouldn't need scaffold again. And if the paintwork is already sound, then this stuff will clean it well enough to not even need repainting. I might try this on the next bit of the house I want to clean, and see if it works out. This stuff is awesome. Buy it.
