Crazy question

3. You could offer

to clean it...your host might have problems with breathing the chemicals of mold killing cleansers.... You could say something like..."I'd love to repay you for your hospitality by helping with a household chore. If you have the cleaners, I would be happy to clean the 'bathroom' for you..."

But you'll have to do what your most comfortable doing...Me? I'd slip out to the store and pick up a bathroom cleanser that removes mold, and just do it. If you give the shower a good rinsing it won't hurt your host.
