Two weeks ago, I made my one tupperdor with cedar trays(bought it from AMAZON). But I found some black colored spots on it today.
These are not fuzzy. I wiped it with clean clothes, scratched with nails, but it never became clean.
To be specific, I seasoned it with distilled water by boiled clean sponge. And got rid of water with clean clothes on much soaked spot. Dried it at balcony without sunlight few hours when I just seasoned.
3 boveda packs(65% RH) are in tupperware and internal humidity level never have raised over 64%.
The internal humidity level is 63% to 64% and the internal temperature is 71 degrees Fahrenheit to 73 degrees Fahrenheit.
Moreover, no cigars in it yet.
What should I do? Do I need to grit the spots with sand paper? Or need to buy new trays?
Any advices for a noob plz.
