Liquid Paper is the brand name of a correction fluid owned by Gillette. A typist first invented it to correct her own typing mistakes but with the advent of computers, the liquid is now primarily used to correct handwriting mistakes. The solution comes in two forms: oil and water-based. The former is harder to remove from wood and other materials than the latter, because oil-based formulas sometimes leave an oil stain. Water-based Liquid Paper is not nearly as effective as oil-based and is only recommended for use when making copies.
Water-Based Liquid Paper
Scrape up any large, thick blobs with a putty knife, taking care not to scratch the wood surface.
Soak a rag in water and place it over the stain, letting the water penetrate the stain.
Wipe up the Liquid Paper. Scrub at the spot with another rag damped with a mixture of soap and water. Dry the spot with a dry rag or let it air dry.
Oil-Based Liquid Paper
Scrape up as much of the stain as you can with a putty knife. Be careful that you don't leave marks on the wood surface.
Use a stain removal product formulated for petroleum or oil-based paints and markers. These are often citrus-based. Mineral water will also dissolve the Liquid Paper but it might remove the varnish on the wood or discolor it. For that reason, test the mineral water or stain remover on a small, discrete area of the wood before using it on the Liquid Paper stain.
Spray or cover the stain with the product and let it saturate the stain for a few minutes. This will dissolve the Liquid Paper.
Wait for the stain to start softening, then wipe with a rag dipped in soapy water. Dry the area with a clean, dry rag. You may have to repeat these steps for best results.
