Your trusty watering can deserves some TLC, but you don’t need harsh chemicals to keep it clean. Whether it’s metal, plastic, or vintage galvanized, here’s how to clean your can with simple, natural methods—no toxic fumes required.

🌿 Why Clean Your Watering Can?

• Algae Buildup – Green gunk can clog the spout and harbor pathogens.
• Hard Water Deposits – Mineral buildup affects flow and water quality.
• Pathogens – Fungi, bacteria, and viruses can lurk inside and infect your plants.

🧼 Supplies You’ll Need

• White vinegar
• Baking soda
• Warm water
• Garden Tool Brush
• Old toothbrush
• Toothpick or wire (for rose cleaning)

No bleach. No synthetic detergents. Just kitchen staples.

🮣 Step-by-Step Cleaning

1. Empty and Rinse

Pour out any leftover water. Give the can a quick rinse to remove loose dirt or sediment.

2. Fill With Vinegar Solution

Mix one part white vinegar to two parts warm water. Fill the can completely—don’t forget the spout and rose (if attached).

Let it sit for at least 30 minutes. For heavy mineral buildup, leave overnight.

3. Scrub the Inside

Use your bottle brush or long scrubber to clean the inside walls. Swirl the water around to loosen debris. Dump out the solution.

4. Baking Soda Rinse

Add a few tablespoons of baking soda and warm water. Scrub again—baking soda acts as a gentle abrasive and deodorizer.

Rinse thoroughly.

5. Clean the Spout and Rose

Use an old toothbrush to clean around the base and spout. For narrow spouts, twist a pipe cleaner or zip tie to scrub inside.

If your rose is removable, soak it in vinegar and scrub with a toothbrush. Use a toothpick to clear any clogged holes.

Let all parts dry thoroughly before reassembly.

🔴 What About Brass Roses?

If you’re using a high-end brass rose—like those from Haws Watering Cans or other traditional makers—it deserves some special care.

How to Clean a Brass Rose Naturally:

1. Detach the rose from the can if possible.
2. Soak it in warm vinegar for 10–15 minutes to dissolve mineral deposits clogging the tiny holes.
3. Use an old toothbrush or soft brass brush to gently scrub the surface. Avoid anything abrasive that could damage the fine holes or finish.
4. For persistent clogs, try poking them with a toothpick or soft wire, being careful not to enlarge the holes.
5. Rinse thoroughly and let it air dry face-down to prevent water from sitting in the rose.

Brass is naturally antimicrobial, but it can tarnish or corrode if left damp constantly—especially when used with hard water. Keep it clean and dry between uses to preserve its beauty and functionality.

Pro Tip:

If your rose has a fine mist spray pattern, regular cleaning is essential to keep it from clogging. A blocked brass rose can cause uneven watering or damage delicate seedlings.

🧹 How Often Should You Clean It?

• Every 1–2 weeks during heavy use
• Immediately after using fertilizers or compost tea
• At the end of the season before storage

🌞 Store It Right

Let it air dry completely. Store indoors or under cover to prevent rust, mold, and UV damage.

Your watering can is more than a tool—it’s a daily companion in the garden. Treat it well, and it’ll serve you for years to come.
