Indigo Airlines — Claims of thorough sanitization prior to every flight seem false

I was on flight 6E 628, Rajkot to Mumbai on 10th April 2022. The plane arrived from Mumbai with passengers & within 5 mins the boarding for the return journey began. It’s impossible that any sanitization was even carried out let alone a thorough one.

Despite that, the crew announced that Indigo sanitizes prior to every flight. Would appreciate if such false claims aren’t made.
