I bought this grimy teal bag with anniversary lining and posted on it around September. If you do a search of my user name in this thread for September, October you will see it. Definitely a * what was I thinking moment*. I did some half hearted spot cleaning. On some advice here, get ready for this: I put it in an old pillowcase and tied it off with a hair band and put it on the delicate cycle , warm water with 1/2 tablespoon of baby shampoo. It was recommended to be done twice. For whatever reason, I only did it once. I have to say, the bag was none the worse and alot of grime was lifted off after doing this.
I wished I had dunked it first in warm water, giving it a light precleaning toothbrush scrub, then put in the washer. I may still do that, again.
At any rate, enough grime lifted off that I enjoy the bag. Lol , I will pretty much dunk anything first and ask later, but I do remember hyperventilating for the first 10 minutes of the cycle saying I can't believe I am doing this!
Obviously this is for a more serious intervention needed than described above. My bag was unusable to me as it was.
