Pure Oxalic Acid Wood Bleach

Use Rainbow's wood bleaching agent to lighten dark streaks in wood to achieve a more uniform color. It's also an effective rust and stain remover.  👍 This agent is not as harsh as the two-part bleaches on the market, and results in a more even color when bleaching smaller surfaces. 💡 It comes in powder form as dry crystals, and must be mixed in hot water. Use only on bare wood.
