How long is the road salt “active”?

Dear community,

Since it will be warmer again tomorrow and at the weekend (+7 degrees here), I wanted to use my moped again, but I'm worried about the road salt that was spread on the street 3 days ago.

Since my moped is almost a vintage car and is mostly made of aluminum and other metals, corrosion can occur due to the salt.

Is the salt still "dangerous" after 3 days on the roads despite yesterday's rain?

Thanks for your answers,

Bern3.
