Cast Iron Pipe Removed - Marked Drive

sloth

Just wondering if anyone out there can help us.....

We have recently had some work done to our house and had to have an old and very thick cast iron pipe removed by the plumber. He had to cut through it and the "dust" has left rusty coloured marks on our shared driveway. We need to remove these as our neighbour (who was very good throughout the building work) has commented on them and of course we want to be good neighbours and remove them.

I have jet washed over them once but you can still see them, plllleeeeeeaaaaaaase, is anyone able to tell me how we can remove them or recommend a very good path and pation cleaner or something?

Any help will be appreciated.

You can spinkle some Black brick dye on the patch, or you can use bitumen paint.

Some sort of acid (white vinegar?) might do the trick.

An alkaline solution such as caustic soda (sodium hydroxide) may do the trick. Always test first in an inconspicuous area ...you don't want to give the neighbour more reason to complain! Or try acetone (found in most nail varnish remover).

Have you tried to vacuum the dust?

Thanks for all responses. It's not actually dust anymore,the dust that was caused by the cutting of the pipe has left a "stain" on the floor. I just thought I should explain it a bit more.

Has anyone added any solutions to a jetwasher before that they could recommend?
