So I looked around a bit, but what is everyone's recommendation for soap/detergent/etc. to put in a 3-1-1 bag? I have a Scrubba that I got for camping and am planning on bringing it along on my 3 week China tour, but I am unsure of what to bring regarding the cleaner, or anything in the 3-1-1 bag really. This is my first time doing carry-on only, even though no one else will be, so I'm a rookie when it comes to liquids and the like. Any advice would be much appreciated.
