Australians have some common methods for cleaning outdoor bathtubs, usually focusing on using environmentally friendly and efficient cleaning methods, considering that bathtubs are exposed to the outside environment and are prone to dust and pollution. Here are some common practices:

1. Mild detergents
Australians tend to use environmentally friendly and non-toxic detergents to avoid the impact on the natural environment. Mild detergents can effectively remove dirt and scale, but will not damage the surface of the bathtub or pollute the water resources used. Common natural cleaners on the market include a mixture of vinegar and baking soda, which can clean and remove odors.

2. High-pressure water gun
Since outdoor bathtubs are prone to dust and debris such as leaves, many people use high-pressure water guns to rinse the surface of the bathtub. This method is not only efficient, but also uses pure water and does not require any chemicals. High-pressure water guns can quickly clean the edges and bottom of the bathtub, especially for those bathtubs installed in the garden or balcony.

3. Soft brush or sponge scrubbing
For stubborn dirt, Australians usually use a soft brush or sponge to scrub. Using soft tools is important to avoid scratching the surface material of the bathtub, especially for acrylic or enamel-coated bathtubs, avoiding hard brushes is key.

4. Drain and rinse regularly
Australia’s climate is relatively dry, but if outdoor bathtubs are not cleaned for a long time, minerals in the water may form scale. Regularly draining the bathtub and rinsing it with clean water is a good way to keep it clean and avoid scale accumulation. Some people will completely empty the bathtub every once in a while and scrub the inside with a soft brush.

5. UV protection and covers
In order to prevent the bathtub from aging due to exposure to the sun and rain, Australians usually use special waterproof bathtub covers. This not only reduces the frequency of cleaning, but also prevents debris such as leaves, dust or insects from entering the bathtub.

6. Anti-mold and anti-algae agents
If the outdoor bathtub is in a humid area, it is easy to breed mold or algae. Australians will use environmentally friendly anti-mold and anti-algae agents to prevent these problems and ensure that the bathtub remains hygienic.

Through these methods, Australians can effectively clean their outdoor bathtubs while maintaining their concern and responsibility for the environment.
