I have a dry cleaning business so we carry a range of pure chemicals which work on curry and red wine and most other really difficult stains.
Thackley - although I agree that many curry stains can be removed from pure wool carpets - your above quote indicates you have the knowledge of stain removal from fabrics. Why therefore, whenever I take garments to my dry cleaners, do they always come back with a printed rider stating "The remaining stains have been examined. We feel that any further attempts to remove could result in damage" - And that for someone who doesn't touch curry - although the odd red wine stain, maybe
Are all carpet cleaners brilliant and do a great job every time leaving most customers happy ?
Every industry has its cowboys and the dry cleaning is no exception. The common perception is that if you have a machine you're a carpet cleaner and its exactly the same in dry cleaning. If you have a dry cleaning machine people assume that you must be able to dry clean clothes but we all know its not quite as simple as that.
To be fair some fabrics are tricky to clean effectively (mainly silk) and there are a lot of variables but in our business we can remove 99 stains out of 100. But the overriding factor is not the stain but the fabric.
If all you send in are suits, trousers, jackets etc with normal food / drink stains then the cleaners really have no excuse. Its normally down to either a lack of care, a lack of knowledge, a lack of ability or a lack of time.
Some of its down to types of equipment and solvent set ups. Some dry cleaning solvents are much worse at getting stains out than others but again a high degree of knowledge can negate to some extent that handicap.
Just out of curiosity its not one of the multiples is it? But a tip for you, if you have a food stain remaining on your clothes (mainly wool, polyester etc) buy a 5% dilution of ammonia and treat the stain with chemical. Leave to dry and the stain should disappear.
