Can you trust vaccines that were made in a year, will help fight Sars-Cov2?

Have you tried piranha solution?

https://en.wikipedia.org/wiki/Piranha_solution

Stuff is extremely reactive, so be very careful. Do you have access to an ultrasonic bath? Sonication with soapy water or a solvent may work and is a safer alternative.

Noelia Vilar Vidal

Well, I hope piranha works for you, please be careful and read all the safety requirements, I can't emphasize that enough. Good luck!
