Silica gel
You can find silica gel packs in nearly any product, from electronics to shoes to medicines and even cat food. For most of us, these packets are simply just there for us to toss away later. However, this is only partially correct.
Silica gel is a drying agent that works by absorbing moisture in the air. Though they won’t do anything to dehumidify a room, in tinier containers like shoeboxes or cat food packaging, the gel sucks up all of the moisture vapor. This leaves your goods looking and smelling fresh since moisture can cause damage and becoming the perfect breeding ground for germs and bacteria.
