Hi Craig
Yes you are right to a point but they will clump (almost always) and you reset pile only when dry. It's a laborious task with a desert spoon but it has to be done. Get a rubber grooming brush for the tassles (JK sells them). Rinse the tassles with an acidic rinse to avoid or correct browning and as for the rest, soak the hell out of them. Or take them fown to the River Ganges for a dip which is what they do now and did a thousand years ago.
I realise this makes it sound easy but Dave L will be doing a course later in the year which will look at this and a number of corrective measures that you will need to understand and believe me, when you start talking to custys about this sort of level of cleaning that percieve you in a very different light.
