How to Deep Clean a Bathroom Thoroughly
A thorough bathroom deep clean goes well beyond the weekly wipe-down — it addresses grout, caulk, behind fixtures, the exhaust fan, and every surface that accumulates grime invisibly. Here's how to do it properly.
Products to Have Ready
- Toilet bowl cleaner (bleach-based)
- All-purpose bathroom cleaner or spray
- White vinegar (for mineral deposits and limescale)
- Bar Keepers Friend (for rust and stubborn stains)
- Grout brush or stiff-bristle toothbrush
- Microfibre cloths
- Cotton swabs
- Magic Eraser
Step 1 — Apply Cleaners and Let Them Dwell
Apply cleaners and let them sit before scrubbing — this is the most common mistake people make. Products work chemically and need contact time:
- Squirt toilet bowl cleaner under the rim and let sit 10 minutes
- Spray shower walls, grout, and tub with bathroom cleaner and let sit 5–10 minutes
- Apply white vinegar to showerhead, faucets, and shower door
Step 2 — Shower and Tub
- Scrub shower walls with a sponge or scrub brush — the dwelling cleaner makes this significantly easier
- Scrub grout lines with a stiff brush — apply more cleaner and let sit if mould is present
- For shower glass doors: apply a paste of Bar Keepers Friend to stubborn mineral spots, leave 5 minutes, scrub with a non-scratch pad, rinse
- Clean the shower door tracks — this is almost always missed. Use a cotton swab or toothbrush to get into the channel
- Remove and clean the shower drain cover — hair and soap accumulate here
- Check and clean caulk lines — wipe thoroughly; replace if black mould has grown into the caulk
Step 3 — Toilet
- Scrub the bowl with a toilet brush — the cleaner has been dwelling and should work quickly
- Flush, then apply cleaner again under the rim and let sit while you clean the exterior
- Wipe exterior with a disinfectant cloth: top of tank, tank sides, the seat (top and underside), seat hinges, bowl exterior, and the base
- Use a cotton swab in the seat hinge area and around the base bolt caps
- Wipe behind the toilet — hair and dust accumulate there
- Final bowl scrub and flush
Step 4 — Sink and Vanity
- Spray and wipe the entire countertop and backsplash
- Scrub the sink basin — focus on the drain area and around the faucet base where grime accumulates
- Clean the faucet with a vinegar-dampened cloth — this removes water spots and mineral deposits
- Polish chrome fixtures with a dry cloth after cleaning to prevent new water spotting
- Clean the mirror with glass cleaner; for toothpaste spots, use a damp cloth first
Step 5 — Surfaces, Fixtures, and Floors
- Wipe all cabinet exteriors and handles
- Remove and clean the exhaust fan cover
- Wipe light switch plates
- Dust the top of the door frame and any shelving
- Sweep, then mop the floor — pay attention to around the toilet base and in corners
