Dry clean only polyester bedding?

[TripTrapTripTrapOverTheBridge]

In the search for a new duvet cover and curtains etc to revamp my bedroom I've been tempted by a lovely set.

The problem is it states it's dry clean only. It's 100% polyester faux silk with polyester flocking.

What would be the most risk free way of doing this in the washing machine or should I just not bother because it sounds a bit daft?! Would it need to dry away from heat too?

Any suggestions for a lovely comfy fabric that can still look lovely,while I'm here?

I seldom get anything dry cleaned - usually stick inside a white pillow case and run a delicate wash (having wet a part somewhere inconspicuous to see the colour didnt mix or whatever). But the only stuff I have for dry cleaning is jackets / occasion wear which would only be used every so often. I don't know if washing a dry clean only item every week would do it any good. And it seems like a lot of hassle having it dry it in a special way. Personally I would forget it and go for something simpler, but I am lazy beggar

It does seem a pain doesn't it I wonder who has time or the inclination for dry cleaning or specially drying duvet covers and pillowcases!
