We have one of your wind up drain un blockers. We used it on a blocked loo as suggested but it has left a lot of black/grey marks on the pan and s bend. How do we clean these off - nothing we have tried seems to work?

Hi Jonathan, providing the galvanised wire hasn’t scratched the enamel, then you should be able to remove any marks with a non-abrasive cleaning paste. This item is primarily intended for clearing blockages in sink wastes/ discharge outlet pipes rather than WC’s, but you should be able to remove the marks fairly easily.
