This guide explains how to clean, maintain and store your watering can properly, so it performs well season after season.

Why Watering Can Maintenance Matters

• Prevents blocked rose attachments and uneven flow
• Reduces leaks and stress cracks
• Stops rust and corrosion in metal cans
• Improves pour control and balance
• Extends lifespan — often by years

A clean, well-stored watering can simply works better and feels easier to use.

How Often Should You Clean a Watering Can?

• Light use: Every few weeks
• Daily or greenhouse use: Weekly
• After fertiliser or feed use: Immediately
• Hard water areas: More frequently to prevent limescale

Regular quick cleans are far easier than fixing blocked or damaged parts later.

Step-by-Step: How to Clean a Watering Can

1. Empty Completely After Use

Always empty your watering can once you’ve finished watering.

Why it matters:

• Prevents frost damage
• Stops stagnant water buildup
• Reduces limescale deposits

2. Clean the Rose Attachment

The rose (sprinkler head) is the most common problem area.

How to clean it:

• Remove the rose from the spout
• Rinse under warm water
• Gently tap to dislodge debris
• Use a soft brush or toothpick if holes are blocked

For stubborn limescale:

• Soak the rose in warm water
• Avoid harsh chemicals that can damage plastic

A clean rose restores gentle, even flow instantly.

3. Rinse the Inside of the Can

• Fill halfway with clean water
• Swirl around to loosen residue
• Pour out fully

This removes:

• Fertiliser residue
• Algae growth
• Sediment buildup

Avoid abrasive cleaners — they can damage coatings or plastic.

4. Dry Before Storage

• Leave upside down to air dry
• Wipe metal cans with a dry cloth

Drying prevents:

• Rust on metal cans
• Smell and residue buildup
• Plastic weakening over time

Storing Watering Cans Properly (UK Advice)

Best Storage Practices

✔ Store indoors or undercover
✔ Keep out of direct sunlight
✔ Protect from frost and freezing temperatures
✔ Avoid leaving cans full of water

Where possible, store watering cans in a shed, greenhouse corner or garage.

Winter Storage Tips

Winter is when most watering cans are damaged.

• Always empty before cold weather
• Store frost-free if possible
• Do not leave outside on soil or concrete
• Metal cans benefit from being fully dry

Most cracks and splits happen due to frozen water expanding inside the can.

Plastic vs Metal: Maintenance Differences

Plastic Watering Cans

• Keep out of prolonged sun — UV makes plastic brittle
• Avoid frost storage
• Clean roses frequently

Metal Watering Cans

• Dry thoroughly after use
• Store undercover
• Avoid scratches that expose bare metal
• Light oil on joints can help prevent rust

Both last far longer with basic care.

Common Maintenance Mistakes to Avoid

❌ Leaving water inside permanently
❌ Storing outside year-round
❌ Ignoring blocked roses
❌ Lifting full cans by the spout
❌ Using harsh cleaners or chemicals

These are the main reasons watering cans fail early.

When Maintenance Isn’t Enough

Even with good care, replace your watering can if:

• The body is cracked or split
• Multiple leaks keep returning
• Pouring causes constant splashing or poor control
• Rust has weakened joints

At that point, replacement is safer and more practical than repair.

Final Thoughts

A watering can doesn’t need much attention — but a little regular cleaning and sensible storage make a huge difference. Keeping roses clear, emptying after use and protecting from frost can easily double the life of your watering can.

A clean, well-maintained can pours better, feels lighter and makes watering far more enjoyable.
