I know this is backwards from the usual post asking how to avoid dry-cleaning! But I have 6 or so fine knit sweaters that ask to be hand washed and I just don't have the time and patience currently to do that. I have a hand wash cycle on my washing machine but it is almost an hour long and that seems to defeat the purpose, too much time spent in water. My dry cleaners is "green" and seems fairly gentle and this season I would really rather pay than hand wash.
The labels don't say either way. Some things I have go through the hand wash directions and then say "or dry clean" and I've had things in the past that say "do not dry clean". These don't give the option, but don't forbid it either! I asked the girl at the counter yesterday and she didn't seem to know.
