Question

How would i go about to remove all comment tags from a XmlDocument instance?

Is there a better way than retrieving a XmlNodeList and iterate over those?

    XmlNodeList list = xmlDoc.SelectNodes("//comment()");

    foreach(XmlNode node in list)
    {
        node.ParentNode.RemoveChild(node);
    }

When you load the xml, you can use XmlReaderSettings

XmlReaderSettings settings = new XmlReaderSettings();
settings.IgnoreComments = true;
XmlReader reader = XmlReader.Create("...", settings);
xmlDoc.Load(reader);

On an existing instance, your solution looks good.
