Birdbaths rank amongst the most worthwhile additions gardeners can provide for local wildlife, offering a safe spot for birds to drink as temperatures climb this spring. Yet they can prove rather troublesome to maintain at this time of year, with sunny conditions frequently causing algae to thrive rapidly and leave a birdbath thoroughly filthy.

Algae becomes more widespread when sunshine arrives, as it warms the water in a birdbath, creating ideal conditions for the plant to multiply and spread. Eliminating algae from a birdbath is absolutely essential, as it produces a slimy environment where bacteria and parasites can flourish, making the drinking water hazardous to birds. James Theodore from Water Fountain Online has revealed a simple method to get a birdbath sparkling clean without scrubbing or resorting to harsh chemicals such as bleach - you merely need a few drops of white vinegar, reports the Mirror.

James said: "White vinegar is the best natural cleaner you can use. Unlike bleach, which is highly toxic if not rinsed perfectly, vinegar is a natural acid that is tough on algae but safe for wildlife."

Why is white vinegar the best way to clean a birdbath?

Many gardeners turn to bleach in their birdbaths because it can break down algae quickly with minimal effort, it is strongly discouraged as it is extraordinarily poisonous to birds.

Bleach can harm birds if they ingest even a minuscule quantity, and it can also remove the natural oils on their feathers, leaving them dry and making it more difficult for birds to fly.

While some people on social media recommend cleaning tricks like placing a penny into a birdbath, this approach is useless and the zinc in the metal can be dangerous to birds.

White vinegar is the best option for cleaning a birdbath as it's slightly acidic, sufficient to combat algae without presenting a danger to our feathered companions.

It's safe for birds to consume and won't damage their feathers if any traces linger, making it an environmentally-friendly choice.

The finest aspect about using white vinegar? It demands little effort and leaves you with a sparkling bird bath in merely 10 to 15 minutes, all without requiring harsh chemicals.

How to use white vinegar to clean a birdbath

Begin by combining nine parts water with one part white vinegar in a bucket. If your birdbath hasn't been cleaned throughout the winter, increase the strength of the mixture by using equal parts vinegar and water.

Then, empty any soiled water onto the ground before tipping the vinegar mixture into the birdbath.

If your birdbath is especially heavy or the algae is particularly obstinate, it might assist to give it a spray with a high-pressure hose before adding the vinegar mixture.

Allow the vinegar to rest in the birdbath for 10 to 15 minutes, giving it time to dissolve the algae. Once the time has elapsed, scrub the birdbath thoroughly with a sponge or bristle brush, and any lingering algae should come away effortlessly.

Next, leave the birdbath to dry out completely in the sun before topping it up with fresh water.

James stated: "UV sunlight is a powerful natural sanitiser that kills remaining bacteria."

Your birdbath should now be completely free of germs and entirely safe for birds to enjoy. Aim to give it a clean once a week or every few weeks to stop algae from building up inside it once more.
