Thinsulate is a common insulation used throughout the outdoor recreational industry. From that background, I would offer the following for any synthetic insulation (thinsulate being one of the name brands on the market):
Avoid washing in the first place! Keep your undergarment "clean" as long as possible by using a base layer underneath. This lengthens the time between washings, which can decrease the garments loft.
When necessary, hand-washing is the preferred method of washing all synthetic garment fills. Use a mild soap, as detergents can leave a residue. Never dry-clean your suit.
Make sure your suit is completely dry before storing. If you're not diving for awhile, hangor store it flat. Don't fold it tightly, as this will break down the insulation.
