The fermentation lock or airlock is a device used in beer brewing and wine making that allows carbon dioxide released by the beer to escape the fermenter, while not allowing air to enter the fermenter, thus avoiding oxidation.
Most wood blinds are treated with a special finish to repel dirt and stains. Wood blinds can be cleaned with a good quality furniture polish and a soft cloth or clean sock. Spray the furniture polish on the cloth and wipe each slat individually. Avoid touching the cords. For heavier cleaning, you can use plain water, but be careful not to saturate the wood.
1 New galvanized metal, a product used to make corrugated sheets, gutters, and downspouts, is usually smooth and is coated with either a layer of oil to prevent white rust or is passivated. 2  Paint applied over this oily surface or clear passivator will peel quickly. Instead, use a water-based cleaner/degreaser to clean a galvanized surface. 2  Most acrylic coatings will adhere directly to cleaned galvanized metal. 3  A weathered galvanized surface develops a layer of white rust, which must be removed to ensure good adhesion of the coating.
