Home Humidor Maintenance/Refurbish 

I have round the best way to seal a humidor is to seal the wood mating surfaces of the box and the lid. Water works well, a water dropper going around the entire surface works well for a good humidor. For a not so good humidor, wax works really well. Just rub the candle over the sealing surfaces, enough times and your lid will fit firmly.

how do we fix the hidnge stop if it breaks? and what do we do if the puck cracks

If I have ash and other debris in my humidor, will this help take care of that? Is there anything else I should consider doing to restore the box?

Looks like a lot of work for a stupid box
