Crest 3D whitening strips?

I’ve been using whitening strips for 6 days and I just learned that you aren’t supposed to brush your teeth before applying them because the flouride in toothpaste will prevent it from fully working. Will it still whiten or did I waste my time?

    In my experience of the several types of whitening strips that I have used the

    whitening effect has been negligible anyway.

    They don't really work.
