Brick wall

[Zothera]

Hello! I've set up an indoor brick wall using cut bricks and would like to clean the "residue" from the joints that has gotten on the edges of the bricks as well as on some bricks. But I don't want to ruin the "feeling" that they are old stirbar, I just want to get rid of the "residue" from the mortar.

Tips?

Hello! I've set up an indoor brick wall with cut bricks and would like to clean the "residue" from the joints that have come onto the edges of the bricks and on certain bricks. But I don't want to ruin the "feel" that they are old-fashioned, I just want to get rid of the "residue" from the mortar.

Any tips?

How does it look, do you have a picture?
When masonry is being built and mortar spills, hydrochloric acid is usually used. Here’s some info from Wieneberger...

If the masonry is to be cleaned with acid, a ready-made mortar acid with a ratio of 1:20 (1 part 30-percent hydrochloric acid to 20 parts water) should be used. We recommend using a sponge board and a bucket with rollers, so the board can be wiped against them to minimize the amount of acid.

The mortar acid should be changed often as dirty mortar acid can cause discoloration.

The acid wash should never be performed more than once from top to bottom. Multiple acid washes on the same spot damage the masonry, voiding the right to make claims.

7. Internal masonry – NEVER use mortar acid or other hydrochloric acid-based cleaning agents​

We recommend that internal masonry is only cleaned with a cleaning sponge and water.

Internal masonry must not be cleaned with hydrochloric acid-based cleaning agents. The fumes from the acid can cause corrosion damage to metal objects.
