How to avoid blockquote formatting problems

I've seen badly formatted blockquotes like these:

Format attributes are sometimes invisible and you are surprised when you add text to a page. The remove formatting command doesn't always work after you've already added text and see formatting problems.

Use the remove formatting tab or Format menu to select Remove formatting:

Replace the text by typing or pasting new text, and then select the new text (warning: depending on the source, you might have to paste as plain text):

Format it as Blockquote code:

And the quote looks good after pasting:
