I recommend these paper travel laundry soap sheets for washing clothes when you are packing a limited amount of clothes:
The container is small and it’s not a liquid. It’s a lifesaver when you may need to do an item or two of laundry if you are going to redo outfits and don’t have access or time to find a laundry facility.
Tip: It does take quite a few of them to work, maybe 3 or 4 in a sink.
Tip: Don’t touch them with wet fingers!! Been there, done that.
Because they’re not very sudsy, you can use them in a washing machine, but it would take at least ten of them. The advantage of these little guys is that they are not liquid, so very TSA friendly. Travelon makes other types of paper, like regular soap and shampoo.
