If you use Apache Commons or Commons3 in your project, it would be most efficient to use a class like

public class UmlautCleaner {

    private static final String[] UMLAUTE = new String[] {"Ä", "Ö", "Ü", "ä", "ö", "ü", "ß"};
    private static final String[] UMLAUTE_REPLACEMENT = new String[] {"AE", "OE", "UE", "ae", "oe", "ue", "ss"};

    private UmlautCleaner() {
    }

    public static String cleanSonderzeichen(final String s) {
        return StringUtils.stripAccents(StringUtils.replaceEach(s, UMLAUTE, UMLAUTE_REPLACEMENT));
    }
}
