Method 1: Cleaning Aquarium decorations with Vinegar
One of the easiest ways to clean aquarium decorations is to use vinegar. White vinegar is cheap and effective at removing algae and other gunk from your decorations.
You can prepare the following items to get ready for cleaning:
- White vinegar
- A clean cloth
- A soft brush
- Remove the decorations from your aquarium and place them in a bowl or sink.
- Fill the bowl or sink with water and add enough vinegar to create a 1:1 ratio of water to vinegar.
- Soak the decorations in the mixture for 30 minutes.
- After 30 minutes, use a soft brush to remove any extra gunk or stubborn stains on the decoration after bringing them out of the mixture.
- Rinse them off with clean water and dry the decorations with a clean cloth.
- Return the decorations to your aquarium.
Method 2: Clean Aquarium decorations with Bleach
If you have really tough stains or algae build-up, you may need to resort to using bleach. This method should only be used as a last resort, as bleach can be harmful to fish if not used properly.
What you need
- Plain bleach without additives
- A powerhead
- A pair of gloves and a mask
- An old toothbrush
- Put on your protective pieces first, including a chemical-resistant glove and a mask. They will keep the bleach from attacking your skin and respiratory system.
- Then, start by removing the decoration from the aquarium. If the decoration is too large to fit in your sink, you can clean it in a water-filled bucket. Also, you can always place it in the bath.
- Fill a bucket with 1 part bleach and 10 parts water to create a diluted bleaching solution. Then, submerge the decoration in the mixture and let it soak for 10 minutes.
- After 10 minutes, rinse the decoration off with clean water. In the process, use a soft toothbrush to remove the rest of the algae and dirt stuck in small corners or tiny cracks. This task will be easy since the bleach breaks down the dirt.
- Be sure to rinse it thoroughly to remove all traces of bleach. Once the decoration is rinsed, you can put it back in the aquarium.
Method 3: Using Muriatic acid and baking soda
If your aquarium decorations, especially rock pieces, are starting to look dull, you can use Muriatic and baking soda to clean them.
Baking soda is a mild abrasive that will help to neutralize the acid when it removes any build-up on your aquarium decorations.
What you need
- Muriatic acid
- Baking soda
- Soft cloth
- Dechlorinator (optional)
- A pair of latex gloves, a face mask, and a pair of protective glasses
- Make sure to wear all the protective pieces before you start using this acid for the decorations. A pair of protective glasses is required to prevent any accidental splash of the acid from hurting your eyes.
- Now, start by removing the decoration from the aquarium.
2. We want to make a 5% cleaner, so it’s 2 teaspoons of acid for every gallon of water. Depending on the size of your decorations, as you want to submerge everything, you can make the solution in a bucket/sink/or the bathtub.
- Then, soak the decoration in the mixture for 20 – 25 minutes, and a tad longer if there are stubborn algae on the stones.
- After 2/3 of the soaking time, do not forget to add 3 tablespoons of baking soda. It is to neutralize the strong acid.
- After that, remove the decoration and rinse it off with clean water.
- (Optional) You can soak the decorations in the mixture of water and dechlorinator for 20-30 minutes more to neutralize in case of any acid solution left.
- Dry the decoration off with a clean cloth, then return the decoration to your aquarium.
