Nice one John, blunt but true!
Thanks for the call on Friday, got problem sorted today and processed order this evening.
Good helpfull advice from Dusty though if had've been a rug

DaveP:
Stains from plant pots are a nightmare especially on wool. Wool is mega absorbant and just loves taking in dyes and stains and not letting them go.
Soil differs from area to area and mixed with plant food / fertiliser and water turns it into an unknown beast. Added to the fact the plant pot or container may not be glazed and the area will be constantly damp and dark which will promote rot, weakening the already delicate wool fibres making cleaning even more difficult.
I've had some joy using plain water rinse first to remove contamination then m/s. Be carefull and keep solution and vac pressures as low as possible to reduce the possibility of ripping fibres clean out.
All the best,
Jason.
