I'm going to use my roommates cleaning supplies to clean our bathroom
Do you think your roommate would do the same with your supplies?
Most likely yeah, We're pretty good about restocking supplies when we need to.
Id say that using your roommates household cleaning supplies is fine. It's pretty normal to do that with your roommate when you're in a good relationship with one another at least. Just make sure to replace anything that runs out.
Yeah, I always do.
Good, because it would be rude not to.
