Oxalic Acid Wood Bleach

Oxalic acid wood bleach is perfect to remove stains on unfinished or stripped wood quickly, making it an excellent choice for those working with wood furniture. It is especially effective in bleaching bare wood surfaces marred by rust stains or iron stains, restoring the wood's natural beauty.

Although not among wood bleaches in the traditional sense of dramatically bleaching wood (such as chlorine bleach), this stain remover excels in refinishing wood surfaces.

How to Apply Oxalic Acid Wood Bleach

Using oxalic acid wood bleach is an excellent method to lighten wood and remove water stains and tannin stains without bleaching it. The acid best restores the desired lightness on dark spots and chemical stains caused by prolonged water exposure or a chemical reaction.

Despite being a strong acid, oxalic acid wood bleach is safe when handled correctly. Before applying oxalic acid on any surface, follow these guidelines:

• Mixing oxalic acid with other chemicals is dangerous.
• Work in a well-ventilated area to avoid inhaling any fumes.
• Always wear rubber gloves, eye protection, and other protective gear. Prolonged contact with bare skin can cause rashes, blisters, and other effects.
• Prepare other ingredients, such as hot water.
• Oxalic acid will not affect the wood’s natural color. To completely remove it, combine a two-part mixture of sodium hydroxide and hydrogen peroxide.

When using oxalic acid bleach to bleach wood, follow these instructions:

1. Dissolve contents of the oxalic acid powder (this is its crystal form) in hot water to create the oxalic acid solution.
2. Apply this oxalic acid solution using a scrub brush to the stained areas, allowing it to penetrate deeply into the wood grain.
3. Let it dry.
4. Should the stains persist, reapply as needed. If oxalic acid needs to be neutralized, immerse in baking soda after scrubbing the area for a minute or so in running water.
