Pressure cleaner can be used to clean mortar off bricks?

[kennyboy]

Has anyone successfully used a domestic pressure cleaner to clean excess mortar from bricks on a new wall?

Our extension looks great but the pointing mortar is also on the bricks in many places and looks unsightly.

I've read in several places that using the correct brick acid works along with lots of manual labour - but there is so much new brickwork on our house it would take me weeks with the spare time I have.

I was wondering if something like a karcher K380MD or similar might do the trick?

Using a pressure washer can also cause severe efflourescence. Brisk acid is the best.

Thanks guys - brick acid with a brush then, looks like I should regard it as a never ending job

Who did the brickwork? get him /her to clean it!

Once the acid's been on, I try scraping the mortar off the brick face before using a brush.

Just using a stiff brush ends up taking out the mortar you don't want to damage.

old trick my father taught me is wet the bricks and then rub them with a brick. works a treat
