Hi
I hand wash the majority of my collection of Hermes scarves with success, but invariably most scarf washers will have one disaster or another at some point which serves as a useful lesson as you don't make the same mistake twice.
Hermes do not generally recommend handwashing and the care label states Dry Clean Only, however many people do wash their Hermes scarves (HS) the same way you'd wash a silk blouse. Dry cleaning will in the main only serve to seal in any marks and stains, whereas handwashing can remove or lessen marks. Most dry cleaners also flattten the hems by ironing which is not desirable. I've had scarves dry cleaned by Hermes, but the results were nothing to shout about but the cost was!
The Yahoo scarf board covers handwashing of scarves in some depth and generally there are many do's and don'ts and handy hints. However, to keep it brief, I'd say to keep to the following pointers, however handwashing is entirely at your own risk! This is how I wash my HS but it's just a sharing of my knowledge/techinique so no law suits please.
Use a spotless grease free clean plastic bowl, cool to very very lukewarm water, use the miniumum of detergent ie Yves Delorme, Woolite etc and make sure it is completely disolved. Swish the scarf in the water, very gently squeezing and do not rub or wring out. Keep the scarf moving in the water, do not leave to soak or sit. Always use a colour catcher or two in the water. You must throroughly rinse the scarf in cool water several times to remove all the detergent. I wouldn't recommend the use of liquid starch in the water it leaves a residue. Sorry to correct another member here, but to drip dry your HS is not advised! I would NEVER EVER drip dry or line dry my HS, this is fatal for colour run as it runs down the scarf, I made this mistake once and never again. Ideally the scarf should be left to dry to damp between two fresh clean towels. Iron when just lightly damp. DO NOT iron when wet or too damp or you will get colour run/transfer. Iron only up to the hems do not flatten them. Re-instate folds if you like your HS this way.
So this is a very brief summary of washing events, it's a lengthy process and the one ingredient you do need is TIME. The biggest enemy of handwashing HS is colour run. In part this may be due to the water being too warm but some scarves will loose colour and others will not. I find the dark reds, dark greens and dark blues the worst offenders and you are most at risk if the colours border white or another light colour. You will soon learn which scarves of your collection are the most tricky to deal with. Some people add to salt to the water to apparently set the dye but personally I don't do this. As far as I've found it doesn't stop the dye running and if you then get colour run the salt then sets the colour where it shouldn't be. In a colour run emergency isolate the area of colour run on the HS over a bowl and pour very hot water over that area which should loosen the colour run. This is very scary so only really for the bold and again at your own risk!
So I hope this helps some first timers, if in doubt don't go there or go for the safer option of dry cleaning. I still get some scarves dry cleaned it depends what is going on and what needs attention.
