Take the crumbs out of your toaster
Yes, for most of us, going over the surface of our toaster with a moist cloth is good enough, but this does not mean that they are fully cleaned. It is also a bad choice to turn them around and wait for the crumbs to fall off. These appliances also have all these holes and gaps that make them a hassle to clean.
But you can use a toothbrush to get rid of all the ancient crumbs that might reside inside your toaster. First, make sure that the toaster is off and unplugged so there are no unfortunate accidents. Then, stick the toothbrush inside and scrub until there are no crumbs stuck inside. Then you can turn it around so they can fall off.
