Anticondens is effective in preventing “hoarseness” caused by condensation which blocks the windway. A combination of organic washing up liquid and water, it releases the surface tension of the little water droplets within the windway, leading to a flat film of moisture. Dribble just a few drops of Anticondens into the windway from the side of the labium (the square sloped hole on the front of the recorder under the mouthpiece) and let it run down over the block surface to the windway entrance. Then blow the Anticondens out of the recorder as described above.
