Hi Guys
I have a customer who wants me to clean her oriental rug. The only problem is a few years ago custy had an accident and spilled blood all over it.
Custy tried to clean up the mess themselves with a cocktail of things including ammonia

This stain is now a few years old but blood is still in the backing and I’m worried it will wick to the surface when i HWE.
The rug is a 30 year old family heirloom and I don’t want to make it any worse.
Any advice would be greatly appreciated.
Simon
