I have allway been OK with 'wick back' on blood and it has never happened to me.
Custy rang yesterday, he is on asprin, bumped his head on a low beam in the middle of the night, blood all over the place!
Evidently he used persil bio to try and get it off, made a right mess of it. Where he put it down neat it has actually scorched the carpet, and has taken the dye out of it but luckily on a doorway section.
Called me out, I used cold water rinse initially, and then cleaned it with Prochem microsan and FF afterwards. I did tell him about wick back and there is now some so I am going back later in the week.
Come on team any ideas, I have looked through 'frequently asked' but nothing there.
