Anyone who has ever rented an apartment (or at least one that wasn’t totally brand new with a sparkly-clean bathroom) has felt the struggle of dealing with an old, not-quite-clean bathtub. If it seems like no matter how much elbow grease you put into it, your rental’s bathtub still has stains—like you know it is clean, but it doesn’t ever look clean—it might just be that you haven’t tried the right solution yet. You’re going to need more than your typical bathroom cleaner spray to get the job done.
