Getting rid of white marks on new layed bricks

[bobajob100]

Is there ant way to get rid of the white marks on the brickwork I have just had laid. And also is there any way to brighten up the blue bricks as they are a bit dull. Will painting the wall with weatherproofing make it any brighter.

Well, you could try rubbing an Arduino or Raspberry Pi on them but I don't think it will work.

Better still ask in the Building sub forum where you are more likely to get a sensible answer.

What you need is some cat 6 cable and chop it up to make like a cat 6 scribing brush then get some brick acid and x run away.
