I got a question folks.

In a few days , some workers are coming home to work (electric, plumbing ..etc.) They may use some of my tools and stuff ( ladder ..etc.) My question is : how many days should I leave the ladder out in the open (under the sun) before I am confident the virus have died.

I have read a few articles about Corona sticking to surfaces for 12-24 hours, and some said 9 days. Any definitive answers ??

Thanks
