Can I use old aluminum foil for cleaning purposes in a kitchen or bathroom?

Yes, old aluminum foil can be used for cleaning purposes in a kitchen or bathroom. It's particularly effective for scrubbing pots and pans, removing burnt-on food, and cleaning glass and tiles. The shiny side of the foil can be used to remove scuff marks from floors and the dull side can be used to scrub away stubborn stains. However, it's important to avoid using foil that has been in contact with acidic or corrosive substances, as it may have become damaged or weakened, and could potentially scratch surfaces. Always test on a small, inconspicuous area first to ensure it doesn't damage the surface you're cleaning.
