Question: A friend of mine has been ill of flu since many weeks ago.

Today, while meeting him, he was reading some of my papers and while reading them he coughed several times. I already washed-cleaned everything else that was around us. The only thing I haven't cleaned yet is my papers. 

I don't know what can I do to disinfect them totally.

I can't spray them because that'd ruin them obviously.

I was reading that the sun can kill some germs, if I put them off directly to sun shine, will they be totally disinfected?

I could get new copies but it will be too much copies, additional to my own notes and remarks on most on them.

Is the some way to clean them without ruin them? 

Thank you in advance.

Answer: 
**Bake your notes in a pre-heated oven for a few minutes.**

According to what virology online, 56°C / 133°F for 15+ minutes — hardly enough to do any damage to your notes that you'd notice.

Good luck.
Expose these papers to black UV light for a few hours
