It's hard to make an old rental bathroom look new again, deep down in its bones. You're limited to surface moves: decluttering the medicine cabinet, painting the walls, or buying a new shower curtain and towels — but those largely gloss over the real heart of darkness — the moldy corners and rusty crevices —that make your bathroom feel gross and icky. This is where a weekend shower tile refresh comes in, and it's both transformative and cheap.
Clean Towels . . . works great . . . found another suggestion to add 2 tsps dawn dishwashing liquid to vinegar load. Doesn't seem necessary, but good to know. Be aware - dryer sheets build up residue on towels over time.
