hi guys any idea if there is a method of doing this type of work this is a four storey house and we've been asked to clean them. they are very very dirty and obviously difficult to get to with the railingswe wondered if giving them a good spray with tfr and jet washing them with pure water might work, has anyone tried this before, i know we can get a brush beteween the rails but its not going to do a great job, top floor is even worse because there is a little balcony and not enough roomm to go back in order to get to the bottom, may have to have access to do those.
like i say above, any ideas please??
