Using your Blomus Salpi Salt and Pepper Mill Set is super easy. First, pull the mill apart and fill it with your favorite salt or pepper. Then, close it back up. To get the right coarseness for your seasoning, just turn the dial on top until you're happy with the grain size. When it comes to cleaning, you can use a soft, dry cloth to wipe the stainless - steel body. Avoid using abrasive cleaners as they might scratch the surface. If you're not using the mills for a long time, it's a good idea to empty them to prevent any clumping. And remember, this set is covered by a 30 - day return policy, so if you have any issues, you can always get in touch with us.
