Remove bullets from the archives list

By default, Clean Machine Archives displays as:

month year
* day title

I want to remove the bullet so that it becomes like this (demo example):

mont year
day title

How do I accomplish it without removing bullets from other non-archived bulleted lists?

If I enter the following code in style.css, bullets will disappear from all bulleted lists (in posts, on pages) which I don’t want. I just want to remove bullets from Clean Machine Archives.

.post ul {
    list-style: none;
}
