I love cleaning ' clean' carpets and suites, the thing is you do what the client asks,whether it needs cleaning or not, it's not just the visible but maybe the fact that if it's been a year then there is a years more worth of crap on it, I hate cleaning mingers and preference the nice jobs in nice houses that have the income to afford to have there stuff cleaned when they want, I have a full service on my car and van every year cause I want to keep them on the road, I probably don't need to but I do anyway, also I tell the client that it won't look much different when it's done but they always say ' but WE know it's clean'
