I moved to a place that has an insulated cinder block building out back, I use that room for that chore, I used to use good old Hoppes #9, but that’s just too strong, I switched to their modern formula, no issues at all. What do you currently use that the Mrs dislikes so much?Wipe Out doesn't have a strong odor.
The only alternative I could possibly imagine would be an indoor range that had a lounge area that allowed cleaning, or maybe a local gun club/range?
