Although I often just use my finger and a little water to clean my bowl and mug after breakfast or dinner on the trail, having a “wash pot” is nice. But too much weight and bulk, right? I recently discovered the Ultra-Sil Kitchen Sink (1.5 inches thick and 4.5 inches wide) as a great alternative. Packs down really small in its own case and is feather light. Best of all you can fill it with water, move away from the lake or stream to avoid contamination and use a small amount of biodegradable soap. Check it out.
In the meantime, be light. Be Safe. Be one with the pack.
