Preheat your oven to 350°F (175°C).
Grate the zucchini, then squeeze out the excess moisture using a kitchen towel or cheesecloth.
In a large bowl, whisk together the flour, salt, baking soda, baking powder, and ground cinnamon.
In another bowl, beat the eggs, then mix in the vegetable oil, white sugar, brown sugar, and vanilla extract until creamy.
Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
Fold in the grated zucchini until evenly distributed.
Divide the batter between two prepared loaf pans and smooth the tops.
Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
Cool in the pans for 10 minutes, then transfer to a cooling rack to cool completely.
