How to Remove Green Stains on Wood

Staining wood often means trying to achieve maximum darkness. Unfortunately, this can sometimes result in green stains from algae or other discolorations. These stains can be removed with some hard work.

Use a chemical cleaner to safely eliminate green stains from wood surfaces, including tables. Though this will require some manual labor, the results should remove the stains as well as kill any algae growing on them. Wear protective eyewear and rubber gloves while using this chemical solution on wood, as well as renting or buying a safe-for-wood pressure washer from most hardware stores.

If you are using a pressure washer, be sure to follow its instructions for setup and operation. In particular, when adding detergent such as mild dish soap, wear gloves and goggles when handling this device.

Algae thrives on wood due to being an aquatic plant, needing both sunlight and moisture for its survival. It often appears on decks or other outdoor wood structures which become frequently wet from dew or rain, often becoming an issue in northeastern states but can appear anywhere across the United States.

There are various products you can purchase to remove moss and algae from wood surfaces. They typically consist of liquid solutions containing chemicals designed to penetrate the surface and kill any plants or fungi on it, while often also including bleach for disinfection purposes and removal of any spores or mold that might have collected there.

Remove green stains from your deck or other wooden structures using natural cleaning solutions made with organic ingredients. There are various recipes for these natural stains; experiment to see which work best on your wood. Furthermore, these natural solutions are safer for the environment than conventional stains which contain volatile organic compounds (VOCs) that may pose health hazards.

Water-based stains often contain toxic or polluting chemicals, while oil-based ones tend to be less durable than their water-based counterparts. If you opt for the latter, sealer is key as this will prevent moisture getting trapped into wood pores which may promote fungal or other growth as well as helping avoid rot; regardless of which stain type is being used.
