I cleaned a naibours lounge and kitchen carpet the usual way around feb time, presprayed with soil break and extracted with weak dilute Hydra dri, carpet was typical nylon rented property carpet but came up fine, this custy has a V messy Girl and Hubby and the carpets are trashed again but as shes just about to give birth wants them clean, fair enough.
But she's asked for me not to use chemicals on this clean as when something is spilt it leaves a ring on the carpet for a while, which she believes is my fault as it never used to happen before I cleaned, has any one else encountered this

Thanks
James
