I always use mine after :) Hope this helped!!
It probably does not matter, but I use mouth wash after brushing and flossing.
Before, of course. Brushing your teeth removes build up of food, plaque and other nasty things. So do you want to whiten your teeth, or the nasty gunk on top? Also, if you brush your teeth afterward, it might not let all the chemicals do their complete job.
The fastest and most reliable solution is the teeth whitening kit from Crest 3D White Luxe Whitestrips Professional Effects: http://bestwhiteningtoothpastepro.com/crest-3d-white-luxe-whitestrips-professional-effects-teeth-whitening-kit-20-treatments/
Crest Whitening Strips are used as a popular alternative for whitening teeth. The ingredients include: Water, Glycerine, Hydrogen Peroxide, Carbon 956, Sodium Hydroxide and Sodium Saccharine.
It is not advisable to use more than one mouth wash because these are basically a chemicals so to avoid interaction between chemicals and detrimental effects use one mouth wash or at least separate each dose by 5 minutes.

I like Crest Whitestrips Seals better

Never. Move to America.
The 5 Minute Whitening Gel works great, but so do the Crest White Strips. It's solely a matter of preference.
