How to clear the highlighting in VSTO

I am developing a word addin in c#. I have used the Find method to highlight the found search terms. (For background, see Find and Highlight issue in word addin).

I use the Find.Execute() method, but I want to use it more than once. But the highlighted words from the previous search are still highlighted.

How can I clear the old highlighted ranges before running method?

 word.Find find = rng.Find;
        find.Wrap = word.WdFindWrap.wdFindContinue;
        //find.Execute(findtext);
        find.Replacement.Highlight = 1;
        Globals.ThisAddin.Application.Options.DefaultHighlightColorIndex = Word.WdColorIndex.wdRed;
        find.Execute(FindText:wd,Replace: Word.WdReplace.wdReplaceAll,MatchWholeWord: true,MatchCase: true);
