69% viscose, 27% nylon, 4% elastane - do I need to hand wash?

[NewYearNewNickname]

It is a pair of black trousers from Episode. I can't stand handwashing and the things that I do hand wash have to wait forever to get washed so wondering whether I can just put these in the machine on a 30 wash.
What do all you domestic goddesses think?
TIA

I put everything in the hand wash 30 setting in my washing machine except dry clean only wool stuff.

Viscose generally washes really well plus with elastin should hold up no problems.

I'd stick it in the machine on a hand wash or woollens wash. If they are fine (should be), no need to be so cautious next time.

Thanks everyone, they are in the machine now, I'll report back when done!!

Just in case anyone was worrying about my work trousers the handwashing cycle on the machine has not altered the fabric or size / shape but neither has it removed one of the marks on them!! At least I know they can go in the machine now :)

Typical. Wonder if stain remover would have had any effect.

I had checked a few times my life is that exciting :)
