📖Life Hack

Did you know that stainless steel cutlery and cookware use black oil (lubricant) for polishing during manufacturing? This black oil doesn't disappear after polishing!!😱😱😱 And it remains on these pots and pans. So, before using any stainless steel cutlery or cookware, you must clean it thoroughly. How should you clean it? Here's a reference. 1. Dissolve oil with oil: Pour a little cooking oil and a few drops of lemon essential oil onto a kitchen towel and wipe the stainless steel surface to dissolve the industrial oil. (This step needs to be repeated depending on the actual situation. The two stainless steel cups I bought today are both 304 grade. The Zebra brand steel cup had less black oil, while the other had more, requiring a total of 3 wipes.) 2. Wash with dish soap: Without rinsing the wiped cup, apply a layer of dish soap. The oil on the surface will mix with the dish soap and turn white. Then, rinse thoroughly with water. Basically, after this treatment, the black oil will be removed. However, some seams or edges are easily overlooked, so pay special attention when wiping~ If you have stainless steel cutlery at home, you can try this experiment when you get home to see if black oil comes off!
