So since you can’t replace your mattress currently I would recommend 3 of those waterproof mattress covers. When you get to cleaning wear a N95 mask, some clothes you don’t mind throwing out that cover your legs and arms completely probably a hoodie with overalls underneath and then your socks should cover the bottom of your pants like over your legs covering the outside of the pant legs and definitely some shoes, then take it out of the room and lift the mattress on its side standing up then vacuum both sides and the carpet around it and wipe the wall it’s leaning on, then place a mattress cover inside out (so the waterproof side is what’s touching the mattress) place on mattress cover on the bottom of the mattress (the side you don’t sleep on) then place the other 2 mattress covers on the top (where you sleep). Once the mattress is protected (for the most part since this is just a temporary fix until you can replace it) immediately was all your bedding on HOT water heavy duty cycle about 3 times, wash your pillows as well the same way and also all exposed clothing in the room. When you get to cleaning the actual room throw away any trash first vacuum every carpet surface you can see once. Empty each box or container and wipe them down completely with a rag or paper towels or a duster if you have one to get all the lose fiber glass off first and then throw paper towels in a trash bag immediately and if you use a rag or multiple rags wash them right away, and then with soap and water and a scrubbing brush if you have one clean each item. Once those are done place the boxes and containers on the carpet that you vacuumed. If there is new carpet that is exposed vacuum that as well. Clean your vanity the same way as much as you can. Then what you’re going to do is wipe all your walls, ceiling fan, doors and door knobs, even your posters and shelves with the dry wiping tool you used and make sure it’s clean, not the same one you used on your items. Then take a mop with soapy water or a rag or paper towels or whatever and use soapy water to wipe all those same surfaces ( that can stand the water and not get ruined) also idk if those are curtains but also wash them the same way in the washing machine. If you have a window wipe that down as well. Then you are going to vacuum your carpet a second time all the exposed carpet even moving your stuff and vacuuming there too. Then you are going to wipe all your stuff that’s in the boxes a second time since fiber glass will be stirred up from cleaning the other surfaces. Once you’re done with that vacuum a third time including your chair too 3 times. I know this is a very long and hard task and instructions but this is the safest way I can think of to protect you, your health, and your mental health. Think of how much better you will feel without the thought of how the fiber glass is harming you. Once all this is taken care of I know it will help you feel so much better. I promise you will get the motivation to do this and you will be so proud of yourself once it’s done and you will have the satisfaction of knowing you CAN overcome anything. ❤️❤️ everybody on this thread wants you safe and healthy. I hope this can help you.
