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

Used this to clean our garage that's finished in K-Rend. We live next to a huge woodland, so moss and green gunk builds up quickly. The garage was fairly well stained and this cleaner has done a superb job. Sprayed on with a 5l hand pump sprayer, left to soak for 15-20 mins and then power washed off. Did the exterior of our greenhouse too and that came up brilliantly. Would highly recommend

I was a little bit sceptical that this would clean our rendering- but I have to say it’s fantastic! Easy to use , a good price and works so well .

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.

Used for cleaning render on extension. 5ltrs more than enough to clean extension 8 x 4 meters with at least 2 lts left. i would say use sealed eye wear and clothes you don’t care about. Also a mask 😷 it stinks of bleach so cant be good for your lungs. if you have pets keep them in doors and rinse the ground after use where the cleaner has been.when using spray i would make sure you spray with a strong jet coming out not a wide spray as when wind catches it and blows back in your face it’s not pleasent. again use appropriate mask etc as aboveif using with a spray bottle i used a spear and jackson one . mixed as specified and the results was good . first time ive cleaned the render and was impressed.would not say render is like new but will say it’s definitely 100% better looking now .

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 don’t normally write reviews however this stuff is truly impressive! I used the product in a 1:4 ratio and applied using a power hose drawing the water from a large bucket. The product literally worked as it was going on and removed large areas of green algae from white render in minutes, I applied the product to a large detached house and completed the task in 30 mins, I am amazed at the results!!!But do be careful, what is doesn’t tell you is it is a very strong bleach/cholride, it will ruin your cloths and any other fabric, so avoid getting it on your cloths or carpets if your moving through the house to get from to back. The product also smells of very strong bleach.That being said I was so impressed the following day I applied it to my patio and left for 1 hr, the stones all looked new within that time.Fantastic stuff!

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.

Used this at the weekend and am very impressed. I used a manual pressure sprayer at about 1:4 (1litre product topped to 5l) and rinsed off with a hose.I could see it working even before the rinse. A couple of areas needed a second treatment and the whole thing took a little over an hour.As with any chemical, read the labels and wear appropriate clothing.The final picture shows what it did to my hoodie (I guess maybe it’s got vegetable dyes in it). It’s my working messily hoodie so doesn’t bother me but if you’re wearing nice clothes be careful, especially if your applying to a surface where it might fall on you or be blown by the wind.
