Went to quote a job today and noticed a large stain on the carpet and was told it was the contents of a lava lamp. It's been cleaned lightly with soapy water but is still fairly noticable. Polyprop carpet (not B.Wilton ) Noted limitations on pre clean survey.
Googled contents : Glycerol water, Wax and Carbon Tetrachloride.
Anyone had a similar problem.
Cheers.
