Tidy detergent

Laundry detergent sheets are a thing. Instead of pouring either powder or liquid into the tub, you drop in a napkin-like sheet of detergent. At home this makes no difference, but these tiny tidy sheets are exactly what you want when you travel. Their concentrated form takes up no room, they weigh less than an ounce, and there’s no possible mess – nothing to spill. I keep some small sheets in a baggie in my luggage. They work in a basin or in a machine. Many similar brands make laundry sheets. I use True Earth Eco-Strips ($13). — KK
