Sea to Summit Wilderness Wash

Sea to Summit Wilderness Wash 8.4 oz is the standard camp-size bottle of Sea to Summit's biodegradable all-purpose camp soap — large enough to cover a season of weekend backpacking trips for one person, or a single multi-day group trip where washing dishes, hands, and bodies all draw from the same concentrated formula. The smaller bottle size is the appropriate choice for pack-weight-conscious backpackers over the 32 oz size that's better suited for basecamp and car camping.

All-Purpose Camp Soap in Practice

Carrying separate dish soap, body wash, and laundry detergent for camp adds weight, pack volume, and the risk of spillage from multiple containers. A single concentrated all-purpose formula handles all three applications with a smaller total footprint. The Wilderness Wash formula is pH-balanced for skin contact (unlike standard dish soaps), biodegrades in soil per Leave No Trace protocols, and is concentrated enough that a few drops handle most dishwashing tasks without excessive sudsing that requires extended rinsing.

• 8.4 oz — packable size for weekend backpacking and light base camping
• All-purpose formula — dishes, body, and laundry from one bottle
• Biodegradable — breaks down in soil when used 200+ feet from water sources
• pH-balanced — gentle enough for full-body skin contact
• Concentrated — a few drops per task, extended use per bottle

Weight and Volume Calculations

8.4 oz is approximately 248ml — at 2-3ml per dishwashing use and 5ml per body wash use, this bottle covers roughly 30-40 dishwashing sessions and 20-25 body wash applications. For a solo weekend backpacker on 2-3 day trips, one bottle lasts several trips. For a group of four on a week-long trip, bring the full 32 oz size to maintain adequate supply throughout.
