There's more to body odor than bacteria. Some folks who are otherwise very clean will exude a strongly metallic odor when perspiring. Diet, medications and various health factors can all contribute to body odor. When I worked in hospitals, especially in hemodialysis, I could smell which patients had hepatitis, which were taking certain heart medications, etc. It wasn't a bad odor or particularly strong, just distinctive.

One of my former co-workers who developed renal insufficiency became so self-conscious about her body odor she began applying deodorant a few times a day. I suppose it sort of helped -- she smelled strongly of deodorant, but her normal odor even without the deodorant wasn't really unpleasant and I doubt most folks would even notice if they didn't know what it was.

Supposedly deodorant and antiperspirants are more effective applied the night before. So a shower and application of deodorant/antiperspirant before bed may minimize some body odors with the next morning's commute. Even if you shower again in the morning, supposedly it won't undo the effect of deodorant/antiperspirant applied the night before.

Due to the usual scares about mosquito borne diseases, including zika this year, I probably smell more strongly of sunscreen and DEET than anything else.

If you apply a coating of a pleasant smelling sunscreen/DEET lotion, you'll probably smell like you just got back from the beach, at worst. Even sweaty, salty bodies smell kinda good after a long day at the beach, combined with the odor of sunscreen. It's a healthy kinda funk. With luck your co-workers will only be envious rather than repelled.
