I cleaned a cream suite last week.Fabric restorer pespray and fibre and fabric to extract.It came up really well except for 2 cushions.In the end I sprayed some ultrapac renovate on still no joy.Then custy tells me thats where me and hubby sit,and its transfer from their jeans.I never use solvents on upholstery,as it tends to leave lighter spots.Transfer from jeans is virtually impossible to completely remove from a cream suite.Just explain it to them and decline the job.Steve
