Bamboo Spun cleaning

Dear Knitters,
I purchased a wonderful to touch, easy to knit, warm to ware yarn/future scarf. It was made out of 77% Bamboo, 23% Polyamide. According to the picture/symbol instructions: DO NOT WASH, DRY CLEAN ONLY.
Has anyone tried to hand wash the finished piece of materials with similar composition? :??

I looked it up and the info I found says it’s machine wash and dry. There are dozens of pages of symbols you can look up. I didn’t look at all of them so I don’t know if they are all the same or what, but here’s one.
