Article: Fish is normally sold in plastic bags or another type of plastic wrapping. For tuna steaks and other fish, there's no need to remove the bags when thawing the fish. The tuna steak will still properly thaw when wrapped in the plastic bag. It's very important that you don't leave the tuna steaks out at room temperature in the kitchen or elsewhere in the house. Fish spoils easily and the fridge will thaw the tuna steak while also keeping it cool at the same time. Room temperature defrosting will thaw the outside layers of the tuna steak while the inside layers go bad. Use a thermometer to make sure your fridge is 5C (41F) or cooler. This is the right temperature for defrosting fish. While it might only take the tuna steak a few hours to thaw in the fridge, you want to be sure that it's completely defrosted before using it. By leaving it overnight, you give the tuna steak enough time to properly defrost. Don't leave the tuna steak in the fridge for longer than 24 hours. The longer the fish is in the fridge, the higher the chances of it going bad. Now that you gave your tuna steak the entire night in the fridge to defrost, you can remove it from the fridge. Take the tuna steak from the plastic bag and inspect it to make sure there's no signs of frost or ice.

Protect both your hardware and yourself by taking care of any electrical components. Shut off your computer first, then unplug the keyboard from it. If you're using a wireless keyboard, remove the batteries. Unplug the power cord if you're working on a laptop. Touch a key to make sure the computer is completely off. If you have a non-USB keyboard, always turn off the computer before unplugging the keyboard. The keys on most modern keyboards fit over small clips and are easy to remove. Wedge a flathead screwdriver or butter knife underneath the corner of a key and lightly pry it up. Then, try to pull the key straight up with your fingers. You may need to wiggle it or pry up the opposite side to slide it off its clip. Take a quick picture of the keyboard with your phone before pulling off the keys. It will help you put the keys back in the correct order later. For an easy way to remove keys, get a wire keycap puller. Find one online or at an electronics store. If you're unsure about removing keys, consult your owner's manual or call the manufacturer. Find out their recommendations for key removal and cleaning. Flip the keyboard over and look for screws. Some keyboards consist of faceplates bound together. If the keyboard has screws, remove the bottom faceplate to wash it separately. Check for hidden screws underneath the keyboard's labels. If you can't remove the keys, you usually can remove the faceplate. Take the keys off afterward, if possible, to give the faceplate a more thorough cleaning. Set out a towel next to the sink. Run warm water from the faucet as you gather the keys into a colander. Then, hold the colander underneath running water, swirling the keys around by hand to rinse them. With a colander, most water and debris rinses off right away. When you're done, set the keys on a towel to finish drying. If rinsing isn't enough to clean the keys, try using a liquid dish soap. Fill a bowl with warm water, then mix in 1UStbsp (15mL) of dish soap to create soapy water. Denture tablets are also very effective and can be used in place of soap. Move the faceplate into a colander or bowl. Try rinsing it out with warm water. Clear out stubborn debris with soapy water and a microfiber cloth. When you're done, set the faceplate aside to dry. If your keyboard is very grimy, soak the faceplate and keys in soapy water for up to 6 hours. Scrub and rinse off everything when you're done. Dampen a clean, lint-free cloth with isopropyl alcohol. Scrub the remaining faceplate to clear out as much debris as possible. Go around the stems that normally hold the keys in place. Make sure the cloth isn't dripping or else some of the moisture may reach the electronic components. Use an electronics cleaning brush from a general store to help remove tough debris. Finish cleaning out the keyboard by wiping away the remaining debris. The key stems are the little towers or clips perched on top of the keyboard. Wipe around the stems to remove debris on the faceplate. Then, dampen a cotton swab with a drop of cleaning solution to wipe off the top of each stem. Change out the cotton swabs as they get dirty to avoid leaving any debris behind. Isopropyl alcohol dries quickly, so it's safer to use than water. Avoid using a lot of it. Dampen each swab lightly. Find a place on your countertop to put the computer parts. Lay out some towels, then arrange the components over them. Keep the parts exposed to fresh air to dry them out. Make sure the computer parts are in a secure spot so they don't fall on the floor or get lost. Keep them inaccessible to children or pets so they dry out fully. Reassemble the keyboard by reversing the steps you took when taking it apart. For most keyboards, you will need to connect the faceplates first. Screw them back together, then set the keys on top of the clips or stems. Usually, all you have to do is slide the keys onto the clips to snap them in place. If your keyboard doesn't work, take it apart again. Make sure you assembled it properly and plugged in all of the cables. Consider calling a professional to give laptops a cleaning. A professional technician can take apart your laptop, find damaged parts, and clean electronic components safely.
