If you are using a Artisteer Skin there is a good chance that the Unordered Lists have a background image set the bullet. If I were you I would just add a bit of CSS to the bottom of your main CSS file that would nullify any styling via a class, that way you could use it as many times as needed.
Something like this:
.cleanlist,
.cleanlist * {
background: none repeat scroll 0 0 transparent;
list-style: none outside none;
}
And then you can have a list like this:
<ul class="cleanlist">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
And that should render like this:
- Item 1
- Item 2
- Item 3
- Item 4
Hope that helps,
