when i back our village,because we building bricks,we found some white stains on it
I think it is not pretty,i scratched at one use my finger and it can be easy to clean, almost like powder,and we use water can clean it.
our builder says once we can use cement to cover it,thay’s a good way, but we keep wondering: dose this white stuff actually will make something to our bricks? or just looks not beautiful?
