I have been not producing anything in that base for almost 4 hours. And these concrete-paved chunks stayed polluted. From what I have read this is forever. It is so annoying, especially knowing that I will leave that base some day.

Smog always settles down onto all kind of surfaces, such as concrete. It does not stay suspended in the air forever.

Can we somehow make it so that pollution dissipates even on fully concreted chunks?

Temporary fix just remove the conrete in the middle of 3*3 machine it will dissipate a little and you can't see it
