Hi all,Well I have done the job and it was a alright. It was a Berber carpet and the blood had been well washed in after the custys attempts. I gave it a rinse then a go with stain pro. and then again. It was difficult to see if there was anything left after being wet. I did have a go on one bit with prochem blood remover but I wasnt that impressed. I did give the rust remover ago which worked quite well. there isn't a massive chance of wick back as it was a fine spray rather than a big spillage however it did seem to have sprayed every where. I finished off with Mpower. I told her to give me a call if after everything if it did somehow reappear but they and I were both pleased.Thanks for all those who gave helpful advice! Before i could answer i would need more info (Robin)Paul (moss) i'm still wondering how you would have tackled the job
