    I want to sterilize my grandfathers and my fathers shaving brush as I want to continue the tradition.

    Take 20 ml of vinegar put it in a tea cup with warm water and a tiny less than a tea spoon of barbicide or dettol into the cup for good measure, let it soak for a few minutes and then give the brush a good rinse under the tap and allow it to air dry.

    You should be good to go after that.

    I would consider not trying, you may do more damage to an heirloom brush than you think. You cannot 'sterilise' a brush. If they have not been used in a good few years then it is unlikely there is much that has survived in the way of bacteria on them. If your immune system is ok then you will shrug off any nasties.

    Perhaps a gentle wash with a anti-bac soap and a good rinse. Use some regular hair shampoo after that.

    would it not be safe to microwave the brush for a couple minutes?

    I wouldn't risk it. It would be likely to melt the glue inside the handle holding the hair plug together. There is also a chance there may be a metal band holding all the hair together inside the handle.

    I'd use a small amount of well diluted tea tree oil and rinse well.

    It's a microwave not a nuclear reactor. What would 2 mins in there achieve?
    You would need to boil water for 15-20 minutes to ensure all bacteria are killed.
    Microwaves are in the non-ionizing end of the spectrum. They are considered radio waves and have longer wavelengths than visible light. Non-ionizing radiation has enough energy to excite molecules, causing them to vibrate. A microwave oven generates a frequency that excites water molecules by vibration. The induced kinetic energy is sufficient to heat to boiling.

    Ionizing radiation is much shorter in wavelength (upper end of the ultraviolet, X-rays, Gamma rays). They cause direct damage to living tissue by breaking chemical bonds and ripping electons off of atoms.
