Our Teak Shield protects wood from food and drink stains. A completely transparent product, Teak Shield makes it difficult for stains from red wine, salad oil, and coffee to penetrate wood, so that fresh spills can be wiped away with a damp cloth. The product is also recommended for impeding mildew growth on furniture used in climates where mildew is prevalent. Teak Shield can be used on clean, naturally weathered wood, or on furniture that has been treated with our Teak Protector. Apply two or more times per year depending on use and exposure.
