You may recall that 4 months ago I installed a new air dryer system for the aux compressor. Last weekend I changed the desiccant for the first time. Today I rejuvenated the used desiccant in our home microwave. The sequence of photos below shows the results at approx minute 0, 3, 6 and 10. <br/><br/>It's 2 quarts of desiccant.
