Despite being a well-known cleaning ingredient, many still doubt whether they should use vinegar or not.

However, do not use undiluted vinegar on your decking.

But if you leave it out on your decking for a prolonged period, the acid can potentially remove the colour of your decking. Some people even use vinegar to turn their decking into a weathered state.

In relation to how long you can allow vinegar to sit on your deck before creating any issues is all depending on the dilution of the vinegar used. There are test results online that show undiluted vinegar can cause issues or stains after 24 hours, we ourselves have tested and we can confirm on uncapped boards stains will occur within 12 hours and on capped boards no stains appear even after 24 hours, but our recommendation would be not to allow vinegar to sit beyond 30 minutes, if you do, pay close attention and regularly check the area. If your using to remove a stain or mould we would advise if you plan to allow the vinegar to sit beyond 30 minutes, to first test in a small area which isn’t or less visible to ensure no damage or stains. The reason for this is vinegar can damaged wood, so caution must be taken. In all honestly for dirt and weathered deck, if you pour vinegar or baking soda on the area and clean, you will see results immediately.

So Why Is Vinegar Used?

So, why is vinegar a commonly used and effective cleaning agent? It is because of the acetic acid that it contains. The acid can dissolve grime and dirt. It is also effective in removing stains. Research also shows that it can kill a range of bacteria, viruses, and other household pathogens, especially when mixed with baking soda.

However, it shouldn’t be used as an alternative to disinfectants, as there are stronger pathogens that can resist vinegar. Make sure to use the proper disinfectant when you want to disinfect a surface.

How to Use Vinegar When Cleaning Decking?

So, vinegar is a safe and affordable substitute for deck cleaning products. But the question is: how do you clean your decking using vinegar? What are the steps to take? Here are some general tips that you can follow to keep your patio clean with vinegar:

1 Gather Your Cleaning Solution & Materials

First, gather all the materials that you will need. You will need 1/2 cup of vinegar, either white or apple cider, 1/4 cup of baking soda, and 3–4 litres of water. Mix all of them in a bucket.

2 Pre-Rinse Your Deck

Next, pre-rinse your decking with water. You can use a garden hose to rinse it faster. Doing this can help remove any dirt and debris on the decking. It also prepares the decking by softening the fibres on your boards. Doing so will allow the solution to work better.

3 Clean The Area With Diluted Vinegar

Then, use a soft-bristle brush and dip it in the solution of vinegar and water. Gently scrub each of the boards. Never use metal brushes, as they can easily graze your decking, leading to more problems.

4 Thoroughly Clean The Area

After washing all the boards, rinse the decking with water. You can use a high-pressure garden hose to remove the solution from your decking. You can also use a pressure washer to rinse the boards. But make sure that you are using a wide tip and that it’s on the prescribed power setting. You may also want to check with the manufacturer first to see if power washing is recommended.

5 What If Stain Hasn't Been Removed

Finally, check for persistent stain spots. For this, you will need to use a stronger solution to remove it. To do this, you will need to mix two parts vinegar and one part water. Apply it directly to the problematic area and sprinkle it with baking soda. Leave it for a few minutes for the vinegar to penetrate the stains. Then, rinse it off with water. If the stain continues then add undiluted vinegar and even baking soda and let sit for 30 minutes, but ensuring to check regularly to ensure no damage, then scrub with a soft brush and clean the solution thoroughly with luke warm water.

Conclusion

As previously mentioned, vinegar as a cleaning agent is cheap and effective. Its great and can be very effective at removing dirt and mould. However, you may want to use a professional cleaning product when it comes to more stubborn stains. Always remember to avoid products with harsh chemicals and test any cleaning products in an inconspicuous area of your decking first.
