Need to know how these fiber affect health.
If it is cloth fabric, you can light a match to it, if it has black smoke coming from it and balls into little pieces and drops of in chunks, then it is made from crude oil. fake fur, polyester, etc. If the fabric is wool, then you will smell the sheep or animal that it came from. Silk smells like worms, Cotton smells like the cotton plant or wood. All materials smell like the original origin that they derived from when a match is set to them. Do not use a lighter as you will distort the smell and it will smell like the fuel from the lighter. Make sure you have an ash try or safety pan underneath, because different fabrics burn at different rates and have very good ventilation. You will know which are toxic and which aren't when you have done the test. Please be careful as some materials are very flammable and toxic.
you don't need to replace anything. all you need to do is get some lube or grease to free up the part that is squeaking.
