I think we all know that water and wood don’t mix well and it is quite possible to experience water stains. Of course, you should always apply oil-based or water-based sealers to protect the wood, however, if you forgot you are probably dealing with water stains now and you want to know how to get rid of them.
When to remove them?
The first thing you need to keep in mind is that the wood will need some time to dry, therefore, you need to remove watermarks when the weather is dry and there is no rain expected.
Of course, if you can move the item you are cleaning into your garage or somewhere dry then the weather wouldn’t be a problem.
How to remove them?
– Use an iron
You would need an iron. Yes, an iron. I know it sounds weird but just hear me out. You want to drain all of the water from the iron then turn it to dry mode and let it heat. Make sure that all of the water is drained before applying this method because even the smallest amount of water may cause new stains. Then place a white cotton cloth on the wood and press the warm iron on top of the cloth.
– Use bleach
Make sure you wear protection when applying this cleaning method – use gloves and a mask.
Make a mixture of equal parts cool water and equal parts bleach. Apply some of the solutions to the affected area with a sponge. Please, do not soak the affected area – apply a small amount. Let the mixture dry completely.
– Use oxalic acid
If the water stains are dark and stubborn you might want to try this cleaning method. Oxalic acid is a very powerful bleaching concentrate, therefore, you need to be extra careful when using it. Wear gloves, a mask, and some sort of eye protection.
Start with mixing a small amount of oxalic acid in a bucket of hot water. Then apply a small amount of the mixture to the affected wood with a brush.
Repeat this step as many times as needed. Once you are done make sure you rinse with water very well then allow the wood to dry.
