Dekers Posted February 9, 2013 Report Share Posted February 9, 2013 I have some water staining (calcium I guess) from a overflow pipe on my house external brickwork. Does anyone have any idea of a simple way to remove this please? Cheers Quote Link to comment Share on other sites More sharing options...
la bala Posted February 9, 2013 Report Share Posted February 9, 2013 seem to remember years ago something called brick acid, cant recall brand name but the name in itself sounds feasable Quote Link to comment Share on other sites More sharing options...
shootnfish Posted February 9, 2013 Report Share Posted February 9, 2013 Brick acid should do it, dilute it with some water then scrub with stiff brush. You can get it from any builders merchants or b&q/ wickes. Quote Link to comment Share on other sites More sharing options...

goodo123 Posted February 9, 2013 Report Share Posted February 9, 2013 Hav a look on internet first, if you use water to take it off it will only come back as more salts are leaching from the brick work. (only what I've seen don't take it as gospel) Quote Link to comment Share on other sites More sharing options...
bevs Posted February 9, 2013 Report Share Posted February 9, 2013 brick acid no good as it only eats away at cement. Quote Link to comment Share on other sites More sharing options...
chady Posted February 9, 2013 Report Share Posted February 9, 2013 Try jays fluid not a guarantee but might work Quote Link to comment Share on other sites More sharing options...
dog tired Posted February 9, 2013 Report Share Posted February 9, 2013 Brick acid or patio cleaner will work but must be diluted otherwise it can discolour the bricks, vinegar also works and is cheaper. Quote Link to comment Share on other sites More sharing options...
unapalomablanca Posted February 9, 2013 Report Share Posted February 9, 2013 pressure washer close up will blow it away Quote Link to comment Share on other sites More sharing options...
shootnfish Posted February 9, 2013 Report Share Posted February 9, 2013 Brick acid will work if you dilute it and wash off with clean water. That's what it is for used it many a time on site to clean brickwork when building houses to clean cement off where its splattered on the walls off the scaffold boards.it won't eat away at the cement if you wash it off after.

Gimlet Posted February 9, 2013 Report Share Posted February 9, 2013 Not convinced brick acid will touch calcite deposits, but it certainlay won't harm the masonry used correctly. You might find it cleans other pollution off the brick and leaves you with a bright clean patch of brickwork and the deposits even more conspicuous. Try a small area first. If not try caustic. The deposits are alkaline so a stronger alkaline solvent may move them. Again try a small bit first. Quote Link to comment Share on other sites More sharing options...

flickrod Posted February 10, 2013 Report Share Posted February 10, 2013 Spirits of salt will remove it,i would dilute it with water, but make sure you wear some gloves and safety glasses as it will burn if it gets on the skin,also do not breath in the fumes......be very careful with it.
