How to use Oxalic Acid
In order to use oxalic acid, there’s a simple process you’ll need to follow. We’ve detailed it below & included a video to make the process as easy as possible.
Oxalic acid is the perfect chemical for removing stains from timber. It’s made from rhubarb leaves & comes in a crystal form.
Oxalic acid is used for:
- Removal of tannin stains in oak or timber
- Removal of iron stains
- Boat cleaning
- Bleaching wood
- Removing brick stains
- Furniture restoration
- Bee keeping
You will need:
- A container
- A brush
- Scrubbing brush
- Safety gloves
- A mask
Avoid contact with the skin & eyes.
The process is extremely simple. We have split it out into 4 steps. It can be completed very simply in a matter of minutes:
- Mix one part oxalic acid with 6 parts warm water
- Apply a liberal amount of the mixture to the timber using a brush or sprayer
- Use the scrubbing brush to scrub the stains
- Allow to dry – the timber will dry without the stains
