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.
Pressure treated wood does not seem to hold paint well, even with a good primer. Stain is usually a better alternative, but since your deck already has paint, it would have to be stripped completely before using stain. In order for the paint to stick fairly well, the surface needs to be as clean and dry as possible.Looking at your pictures, I see a fair amount of algae in the grain of the wood. This is a very normal condition. You should however, use the pressure washer and bleach/water/TSP shrub down method to clean it up.n order for the paint to stick fairly well, the surface needs to be as clean and dry as possible.
