Hi,
Cleaned a mattress for a client in Worcestershire today and he has a friend who is looking for someone to remove iron / rust marks from a shower tray. From what I can gather the shower tray is stone resin and has been marked by constant water dripping through very old pipe work onto the base.
This is not my line of work at all but told my client I would ask around to either a) find someone willing to do the job or
b) get some hints on how to remove the stain so the homeowner can have a go themself.

From what I can gather rust removal from stone can be quite tricky but if anyone can help please post.
Thanks,
Conrad
