Electronics
If you still have any old game consoles, DVD players, TVs, or computers lying around, be aware that extreme temperature fluctuations could damage them.
Electronics are especially sensitive to damage by condensation because moisture can get into the circuits. Water getting into anything electrical can also be a severe danger due to the risk of electrocution.
So this particular item can be a fire hazard you should definitely avoid storing in your garage.
Off-season clothes
The truth is that most people keep off-season clothes in their garage. But it’s something you might end up regretting leaving there during the winter months.
Melting snow off your car creates lots of moisture and can seep into cardboard boxes, ruining them and what’s inside.
If your closets are overflowing, we suggest storing your extra clothes in plastic bins and keeping them off the concrete floor and on shelves.
