I accidentally spilled some white powder, which is a carcinogen, on my MacBook while working in the lab. I managed to wipe down the top with alcohol, but now I can see some of the powder is stuck underneath the keyboard. Is there a safe method to clean it out?

There are special keyboard vacuums designed for cleaning out dust and debris. That might help with your situation too!
What kind of powder was it? Knowing that could help determine the best cleaning method.
You could try using compressed air to blow out the powder from underneath the keys. Just be careful not to blow it further in!
If you have a negative airflow enclosure, that could be a good way to blow out the contaminants safely. Just set your MacBook inside and use a can of compressed air to clear it out.
