It is possible to remove these, but it's quite a labor intensive process. They were probably generated in the first place through authoring the text content in IE (as rich text editing in IE inserts font tags when styling font color).
I would recommend opening the site for editing in Firefox (http://www.getfirefox.com), removing all formatting either by using the remove formatting button on the text editing toolbar, or if that doesn't work, entering HTML editing mode, and manually removing the font tags (this will screw things up in that it will remove all specific color formatting), then re-adding the formatting. In Firefox, color formatting should get added using tags instead.
We're are looking into improving out text editor so that code output becomes standardized and valid XHTML across all browsers, however this feature is some way off.
To the best of my knowledge these font tags will render correctly in all browsers and won't negatively effect your search engine rankings, so unless XHTML validation is very important to you, it is worth considering not changing it at all.
