I feel really daft about asking this - and am fully prepared to be told I'm being a bit silly.
I know that when I buy new furniture, I usually clean it down before I use it.
Tomorrow I'm getting a brand new sofa and armchair delivered. I've never actually bought a new sofa/armchair combo before - I've always had hand-me-downs! Should I be doing something to clean the upholstery before using them? (The sofa is an IKEA one with a separate cover which can be machine washed apparently). It would be a real faff to have to clean and dry them, so if I don't have to I won't...
Thanks
