Wood bleaches lighten the natural colour of the grain pattern of wooden items. Bleach can lighten wood all over, reduce the appearance of stains or dark spots or to disinfect a wood item that was contaminated with a substance like mould or mildew. There are a few different types of bleach solutions that you can make to use on wood. Each can be effective in lightening wood. Your choice might depend on what supplies you have on hand.
Use a peroxide bleach when you want to remove a wood's natural colour.
Add equal amounts of hydrogen peroxide and sodium hydroxide to a plastic container.
Mix the substances together with a paint stirrer. Apply it to the wood to lighten.
Remove stains or disinfect wood with a chlorine bleach. This type of wood bleach will need to be diluted.
Dilute the chlorine bleach with water in a plastic container. Use a 1:4 ratio, meaning 1 part bleach to 4 parts water. This should be a strong enough mixture to strip the stain or colour from the wood with the bleach.
Stir the bleach mixture with a paint stirrer. Apply it to the wood.
