Thanks a lot. One less thing to worry about. I will need soap to wash off the sunscreen (I use the non-chemical one based on zinc oxide/titanium dioxide) before sleep and it cannot be removed just by washing with plain water (at least, I never could). Citronella wash is indeed expected to do double duty: cleaning and repelling mosquitoes, but I think I can skip the second feature. The hike will be in Sierra Nevada. I had before a couple of (reasonably) close encounters with black bears (one at the Lake Tahoe and one in Kentucky), but they ran away as soon as they saw/heard me. But there was plenty of space for us to go our separate ways. In the tent it would be a little more crowded. That is why I was asking this question.
Thanks to everyone for their help.
