Pocster Posted April 9, 2022 Share Posted April 9, 2022 Following on from my other post . Some very dirty quoins ! . Pressure wash won’t touch it - any way to clean them up a bit ? Secondly my shuttering leaked a bit over my wall . Some ‘ smeary ‘ cement on it . Brushing it when dry helped a bit - but a recommended product to clean it up a bit appreciated.

joe90 Posted April 9, 2022 Share Posted April 9, 2022 That Bostik type stuff cleans Mortor stains as well so may clean up after your coping stone bedding 🤷♂️ 1 Link to comment Share on other sites More sharing options...
TonyT Posted April 9, 2022 Share Posted April 9, 2022 I use wet and forget for green build up on paths etc. I think the brick acid would be a better shout 1 1 Link to comment Share on other sites More sharing options...
Pocster Posted April 9, 2022 Author Share Posted April 9, 2022 Ok ok , I’ll forget “ wet & forget “ ( though the product name is the best ! ) . Ordered the boringly named bostik “ mortar and brick cleaner “ Link to comment Share on other sites More sharing options...

Always scared the acid will burn the entire wall away ! . Went over more stubborn bits later with it neat . Does the job 👍 Says not to use on sandstone. So tried my favourite ‘ wet & forget ‘ on them - jury is still out . According to the reviews you need to leave it and be patient… 1 Link to comment Share on other sites More sharing options...
Pocster Posted April 13, 2022 Author Share Posted April 13, 2022 Tried now both products on the quoins - no real joy . On eBay I see ‘ memorial head stone cleaner ‘ 🙄🙄🙄😁 Link to comment Share on other sites More sharing options...
TonyT Posted April 13, 2022 Share Posted April 13, 2022 Wet and forget is a selective herbicide so good for algae. Etc but that’s not what you have on the wall.. get the acid on And then washed off Link to comment Share on other sites More sharing options...

joe90 Posted April 13, 2022 Share Posted April 13, 2022 Around @pocster,s area stone goes black from Avonmouth (an industrial area and docks with a history of pollution) I know because I used to live close by (but escaped 😇). 1 Link to comment Share on other sites More sharing options...

Yes . They do go black . Real black some of them ; so technically it’s “dirt” from pollution ???? 1 Link to comment Share on other sites More sharing options...

bassanclan Posted April 13, 2022 Share Posted April 13, 2022 For headstones use high concentration bleach. I think a brand of it is HCL Link to comment Share on other sites More sharing options...
PeterW Posted April 13, 2022 Share Posted April 13, 2022 Possibly worth looking at something like Lithofin Power-Clean which is very good at ingrained dirt on stone. It’s alkaline so doesn’t dissolve like an acid will. 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted April 13, 2022 Share Posted April 13, 2022 Isn't there restriction on buying acid for cleaning after that woman was blinded by her ex with it. And "Watch and Wipe" is a much better trade name. Link to comment Share on other sites More sharing options...

Pocster Posted April 14, 2022 Author Share Posted April 14, 2022 Will try the LithofinPower-Clean as recommended by @PeterW Reluctant to use acid unless I really have to and equally the same with bleach . 1 Link to comment Share on other sites More sharing options...
SteamyTea Posted April 14, 2022 Share Posted April 14, 2022 3 minutes ago, pocster said: Reluctant to use acid unless I really have to and equally the same with bleach Why I think that cement is alkaline, so the acid will remove it, and not damage the stone to much, which is lower down the pH scale. Bleach acts as an alkaline solution, so is probably heading in the wrong direction. It is all to do with the free electrons and the movement of ions, not that I really understand it.
