Can I machine wash a dry clean only viscose and polyester dress??

[plipplops]

I've got a lovely viscose dress with a polyester lining which is dry clean only. I don't want to ruin it so will grudgingly pay for dry cleaning, but if it'll be fine in the machine (with will detergent on a super gentle cycle?) I'd rather do that?? Any thoughts??

I have done this but like you say on a delicate wash. The trick is to avoid the fast spin so 600 at the most. If you have a non spin program even better.
Then hang up to dry naturally.

Perfect, thanks! I have a no-spin option (I think?!).

I'd disagree on this one - if it's a dress that you love deeply. I'm a real 'bung everything in the wash' person - I don't even know if my local dry-cleaners is still a going concern - and the only trouble I've had is with viscose items with linings - I've had a lot of differential shrinkage.
