Have Rec Tec's griddle grill and seasoned yesterday according to"their" You Tube video. I used Avocado oil which has a higher smoke point similar to grapeseed oil. For some reason it did not take very well. You can basically rub it off with your thumb. Do I need to completely re-do and if so ,what is the best way to get the old off again? There was 5 coats of oil put on every 30 mins.
