Already knew this when it was recommended to put re-wearable masks in direct sunlight for a period of time. Plus the docs said that the virus would expand in the heat and humidity making it almost impossible to penetrate membranes. Another fact is to remain hydrated because the virus, even without the heat and humidity cannot pass through the membranes if they are wet.
The Summer will not kill off the virus. It will stop the mass spread. A coronavirus is a virus like the flu and common cold. We can try to kill the strain but it really never goes away. When flu and cold season hits each year, so too will it be novel coronavirus season as well. SARS has never gone away, the Asian Bird flu has never gone away. We combat these with shots that act like armor which some call vaccines but are not vaccines. Until these are developed for COVID, then it will hit just as hard come the flu and cold season for those who have no resistance against the virus.

My wife, an RN all of her adult life and still a great one at age 80, showed me how to make sure our cloth masks would be virus/germ free for our next trip to pickup groceries.
She had me park our vehicle in the sunlight, facing the sunlight. Then, we lowered the windows about 2 inches.
Last we put our masks upside down on the dash.
So by the next time we put them on, they should be germ and virus free.
