Learn everything you can about the extraction tek you plan on using and plan on following it exactly to obtain best results. If there are ever any issues during your extraction throw nothing away until you know without a doubt that you won't need it anymore. We are all here to help one another out.
Good luck when you decide to do it, again welcome to the nexus
