Part dryer machines work by heating water to a temperature which will dry out the material.
You then use a small amount of oil or paint thinner to dry the part and then place the dryer on a low heat setting.
This method has a small risk of burning the material if the part is not well-treated.
If you do use this method, you will want to wash the parts as thoroughly as possible to avoid them drying out.
You can find a guide to dryer repair parts in the parts manual on the parts supplier’s website.
