What you need for this tutorial;
Hardwood is known for its strength, durability, and warm appearance. It is therefore a popular type of wood for decking, patios, and other outdoor applications. However, dirt, green deposits, and graying can severely affect its appearance. A common tip is to clean hardwood with baking soda, but is that actually a good idea?
In this article, you will read all about the pros and cons of using baking soda on wood, and discover why the Osmo Patio Cleaner is a much safer and more effective choice.
Cleaning hardwood with baking soda: pros and cons
Cleaning with soda or baking soda sounds appealing. It is inexpensive, readily available, and is often touted as a natural cleaning agent. However, there are significant disadvantages when used on hardwood surfaces such as decking or patios.
Possible benefits
- Soda is grease-dissolving and can clean gently
- Easily mixable with warm water
- Biodegradable (in pure form)
Disadvantages of cleaning hardwood with soda
- High acidity or alkaline effect: soda can extract natural oils from the wood, causing it to dry out
- Discoloration: prolonged use can affect the color of the wood
- Damaging wood: with incorrect use or in high concentrations, soda can damage the wood fibers
- Not suitable for long-term protection: soda offers no protection against UV radiation, moisture, or new soiling
- Harmful to plants: rinsing off soda can damage your plants or the grass around your patio
Conclusion: although soda sounds like an environmentally friendly alternative, its effect on hardwood is often negative rather than positive. Fortunately, there is a better alternative.
