/cgl/ - Cosplay & EGL

I actually had a question. I wear lolita very infrequently, so I've never washed my skirts (given that they've all been worn maybe twice). I noticed that on almost all of my clothes, in the dry cleaning-section, it says that "garment can be cleaned using petroleum based agent". I don't frequently go to the cleaners and didn't know there were different methods you could ask for. Do you all usually specify this, or do you just take your clothes in and get them cleaned (without specifying any special methods)?
