Thats great to hear that you had some success with Ecotex.

I anyone has experience or recommendation for tea stain on sisal.  I have a customer who had an electrician spill his cuppa on their brand new sisal.

Tell the Leccy to replace the carpet.
Else use paraffin and a match.

No its no fuss just ask Mr Birchdale - although by his own admission " To be honest the sisal looked no different at all when I left" so that may just present some problems when it comes to getting the bill paid!
