A shower caddy takes the brunt of daily use — shampoo drips, hard water, and warm moisture all conspire to leave it coated in soap scum, mineral scale, and eventually rust. The video above shows the process in action; the steps below give you a material-by-material method you can follow at home, in a holiday rental, or in a hotel room in Greece. Getting this right once a month keeps the caddy looking new and protects guests from unsightly stains.
Why Shower Caddies Get So Dirty So Fast
In Greece's hard-water regions — which cover most of the mainland and the islands — calcium and magnesium deposits form a chalky white film on any surface that gets wet repeatedly. Combine that with the fatty residue left by shampoos and shower gels and you get a sticky layer that traps grime and creates the perfect breeding ground for mildew. Metal caddies face the extra challenge of surface rust, especially where the chrome or stainless coating has been scratched.
Holiday rentals and hotels face an accelerated version of this problem because multiple guests cycle through weekly. A caddy that looks acceptable after one month of single-household use can look neglected after a single busy holiday week.
Choosing the Right Cleaner for the Material
Plastic and acrylic caddies respond well to a simple dish-soap scrub — they do not need acid-based cleaners and harsh chemicals can dull the surface. Bamboo caddies need gentle soap followed by a light oiling to prevent the wood from cracking in the humid bathroom environment. Metal caddies — the most common type and the most prone to hard-water rings and rust — benefit from a white-vinegar soak, which dissolves mineral scale without scratching, plus a baking-soda paste for stubborn rust spots.
Avoid bleach on metal caddies: it can accelerate surface corrosion. Avoid abrasive steel-wool pads on chrome finishes for the same reason. A soft-bristled brush or an old toothbrush gives you the scrubbing power you need without causing damage.
How to Clean a Shower Caddy: Step by Step
- 1
Clear and rinse the caddy
Remove every bottle and accessory from the caddy and take it out of the shower. Rinse it under warm running water to loosen any loose soap residue and hair. This makes the cleaning agents work faster and stops debris from diluting your solution.
- 2
Soak in white vinegar solution
Fill a bucket or the bathtub with one gallon of warm water and half a cup of distilled white vinegar. Submerge the caddy fully and leave it to soak for 20 minutes. The mild acetic acid dissolves limescale and mineral deposits that scrubbing alone cannot shift. For plastic or bamboo caddies, use plain warm water with a few drops of dish soap instead.
- 3
Scrub every surface and crevice
Using a soft brush or old toothbrush, scrub the shelves, drainage holes, and any joints or welds where grime hides. For stubborn hard-water rings on metal, make a paste of baking soda and a few drops of water, apply it directly to the spot, leave for five minutes, then scrub in circular motions. For rust spots, squeeze lemon juice over coarse salt and rub it on with a non-metal scourer.
- 4
Rinse thoroughly and dry completely
Rinse the caddy under clean running water until no vinegar smell or soap residue remains. Then — and this step is the one most people skip — dry it completely with a clean cloth or microfibre towel. Leaving moisture on metal is the main cause of rust; thorough drying after every clean dramatically extends the caddy's life.
- 5
Protect and prevent future build-up
Once the caddy is dry, run a thin layer of car wax or clear furniture wax over metal surfaces. This creates a barrier that repels water and slows scale build-up. For caddies in hard-water areas, a weekly wipe-down with a damp microfibre cloth between monthly deep cleans keeps things manageable without a full soak every time.

FAQ
- How often should I clean a shower caddy in a holiday rental?
- Once between each guest stay is the minimum. In practice, a quick rinse and wipe after every stay, combined with a full vinegar soak once a month, keeps the caddy looking new for guests and prevents rust from establishing itself.
- Can I put a metal shower caddy in the dishwasher?
- Most chrome or stainless-steel caddies should not go in the dishwasher. Dishwasher detergent is highly alkaline and the high-heat drying cycle can strip protective coatings and speed up rusting. Hand-washing with the vinegar-soak method is safer and just as effective.
- What removes rust stains from the shower wall left by a rusty caddy?
- A paste of lemon juice and baking soda applied to the stain, left for 10 minutes, then scrubbed with a non-abrasive sponge removes most rust marks from tiles and grout. For stubborn stains on ceramic or stone, a commercial oxalic-acid cleaner works well — rinse thoroughly afterwards.
