I cleaned a rug 5 weeks ago .I was man made fibres .As I was cleaning it pink blotches appeared I bought this to the customers mothers attention ( as customer was at work ).I thought it was all part of the compositon of the fibres and when dry would dissapear as it was not noticeable until wet . They rang me up yesterday saying that the blotches have got worse and what was i going to do about it . Have any of you guys ever had this problem , if so how did you sort it ?
