J.K. Rowling is describing the effects of a sunny summer in Ron and Hermioneâs skin, to which we can suppose Hermione is tanned. Other passages of the seven-part novel talks about Hermioneâs cheeks going pink â which could lead again to a white skin.
Baking Soda. Using baking soda is another way to remove rust from metal. You can make a paste by mixing baking soda and water. Make sure that the solution is pasty enough to adhere to the surface, then spread it onto the metal and let it sit. After the rust is loose, you can scrub it off.
How to treat rusty metal: * Clean the piece well with soapy water and buff dry. * If rust is flaky, scrape off flakes with a grill wire brush. * Seal the piece with either a (non sticky type) satin clear sealer or oil. * If using oil, allow piece to sit for a bit, then buff well, so no oily residue is left behind. Buff the next day as well.
