Lysol on microwave, how to clean off?

To further @Tetsujin's answer.

The Lysol product you have specified as Lysol Clean & Fresh Multi-Surface Cleaner is made of a number of active ingredients. The primary decontaminating component is Alkyl (50% C14, 40% C12, 10% C16) dimethyl benzyl ammonium chloride. This is a member of what are known as Quaternary Ammonium Compounds or Quaternary Ammonium Cations (QACs). These are all very effective disinfectants against most bacterial pathogens and a wide range of viruses (including SARS-CoV-2 the cause of COVID-19 - see the list and concentrations here). There are a bunch of other things in there too, but most of it is ingredients that allow the QACs to work better, this includes the alcohols (surfactant), EDTA and Tetraborate (mineral sequestering - for hard water, which can inhibit QACs), or ways to make it smell nicer or look pretty.

QACs are generally irritants - they make your skin red and itchy, but they can also cause more severe damage on more sensitive tissues such as lungs, eyes and intestines if inhaled or swallowed. Generally these compounds are safe to use on hard surfaces like your microwave, but not on porous surfaces because the porous surfaces can absorb the disinfectant. Note that they are pretty common as bacteriostatics in contact storage solutions, eye-washes and nasal sprays (see Dermal section) - so the risks are relatively low.

Use of QACs on hard surfaces is fine - just wipe with water a couple of times after use will dilute it enough that it is no longer a problem for most people.

The vents on your microwave are not considered porous - porous surfaces are things with small holes that will absorb the ingredients and not allow them to be washed off easily. Examples of porous surfaces are unsealed wooden surfaces (e.g. chopping boards), sponges (you can use these for cleaning with though - just don't eat off them) and unglazed pottery/crockery. If you have used a QAC cleaner on these sorts of things, you should throw them out or re-purpose them so that you are not eating off them

Long story short - wipe with water a couple of times and you will be fine.

Lysol is a trade name, covering a whole family of quite different products. You will need to be more specific.

In short, though… you rinse it with more water until it's gone. If it got inside places it shouldn't, then your choice is to attempt a DIY take-apart [really not recommended] or give it to a professional… or ignore it & eventually it the smell will go away, hopefully.
