washable? (Photek background in a bag)

[rubyscooby]

Hi I was wondering if any one knows it the background in a bag is washable? I just did a photo shoot with a baby sitting on it and it got dirty. I am a bit afraid to throw it in the washer dryer though. I have looked for specs at all the stores selling them and have not found anything.

Plain or painted? the spec sheet says the plain ones are easily machine washable (haven't got it here, but . . . ), try cool, gentle cycle. Maybe set it up on the stand instead of running it through the dryer. The paints on the patterned ones can run/diffuse when wet (I had a shoot at a dog club picnic, and it was raining - got several pronounced (to me, my wife doesn't see them) streaks on it where the dye ran). They say these can be washed if necessary, but not too often, and I'd agree with that. I use a fleece blanket (same or contrasting colour) to put the dogs on and let the background be a background.
