Not such a bad idea.

Hopefully at this stage you have only used Tech Wash and NOT any of reproofing products like TX Direct.
I think it may be time to go beyond Tech Wash and do a wash using conventional detergents and worry about repellancy later. I think I would try washing it with one of the latest type of liquid detergents then do an extra rinse cycle to make sure that the detergent is out of the garment.
The shower trick recommended by our Turdish friend above is a good way of checking if the detergent is properly rinsed out because you can see or feel any remaining soapy deposits.
You certainly have to make sure you get that dust out or it will abrade the fabric, membrane and coating internally. Only when it is removed can you dare use the proofing to refurbish the repellancy. TX Direct and other such products seal in remaining dirt forever.
