Bright marks appearing on the cigars can basically have two causes. If the marks are light gray in color, dusty and can be easily wiped off with a cloth, then the spots are only a result of the normal aging process of the cigars, which does not impair the taste of the cigars.
If however the spots are crusty and blue-green in color then the cigars are infected by mold. Mold may form if cigars are stored at excessively high humidity levels. In such cases the infected cigars must be removed and the humidor should be cleaned carefully with a dry cloth. The humidifier should be cleaned carefully with warm water and if there is mold on the humidifier, the humidifier should be replaced. Under no circumstances should the infected cigars be put back into the clean humidor.
























IF HUMIDITY IS TOO LOW FIX and it is a constant problem and nothing works. Then try the following only after everything else has been tried!
Season humidor with warm distilled water on a new sponge. After seasoning, put still wet sponge(but not dripping) on 2 cheap cigars that will be tossed later. Leave for 24 hrs. Then, re-season again same way, leave sponge again. Wait 24 hrs. and do again. After the third time leave the sponge there for 3 more days with the humidifier. After that, discard sponge and cigars. By this time, the pores in the wood would have absorbed enough moisture and stabilized the climate in the humidor. Sometimes the wood is so dry that even after seasoning it once, its not enough moisture to keep a humidity above 58%. This fixes that.
