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

This product is amazing for use on house render cleaning. Tested a small section with a brush as I didn’t have a sprayer, the results are great with very little effort.

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.

The cleaner gave good results without too much hard work.

Amazing product never thought it work anywhere as good as it did. Easy to use works in 15 mins restored colour back like new. Make sure you use protection whilst using. Top product.

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

I was very sceptical at first this would work as advised. But it superceded my expectations. I cleaned both mine and my neighbours house, which had not been cleaned in over 8 years so what alot of hard wearing dirt. After a few hours the houses looked like new. The proof is in the pictures. Defo recommend for average diy clean.

What can I say about this product fantastic results .my building is 15 years old and first time washing it .my steps that I followed. Use pressure washer to losten the dirt and rinse down the walls first .after that the walls need to be slightly wet for chemical to work . I applied 2/1 2 liters of water to 1 litre of chemical. I used 10L sprayers .spray it on leave for 30 minutes the longer the better.make sure walls don't dry in this time if they do light dusting of water with pressure washer enough just to slightly moist the wall again.you will start to see the walls going white as well. After 30 minutes was it down take your time .if you see any patches apply more chemical and leave for 20 minutes making sure walls don't dry repeat as required After using chemical 2 times I left wall to dry for whole day .went back next day applied CHEMICAL to any PATCHES repeating the above process and stains were going .you will never achieve 100 percent result as render does get old and lose colour as well. I bought the big container as this will give freedom to use more if needed its weel worth buing the big one i am going to wash the whole house just done 2 sides already .anoth 2 sides to go. So summery 1 try using pressure washer clean down the walls first removing lose durt 2 once wall moist apply chemical for old walls 2/1 is good 3 leave for 30 minutes making sure walls are moist. 4 wash it down with pressure washer 5 apply chemical again where required repeat as many times make sure you give chemical time to work 6 Let walls dry for 24h and then see any patches repeat above .

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.
