I agree try them at home. I had Purex pods and they dyed my clothes blue that trip. All my whites, had blue ink like stains. Never came out.
I put whatever I take in my checked bags. Last trip was dryer sheets and Tide single use packets. Another time a small jug of All.
Loved our last town house with the washer and dryer in the home! It really saved on what I packed for PJ's, undies and socks.
