Stainless steel small bar sink are tough and durable. They will give you a lifetime of use if they are kept clean and taken care of every day. Considering proper care, they can resist scratches, rust and stains. Since most detergents contain chlorides, which can cause stains, and some water can have a high concentration of minerals, you will have to rub your sink with nylon and soap or a synthetic sponge and rinse every day. Allowing mineral deposits to settle can cause rust stains and discoloration. Dry with a paper towel. Rinse your sink after each use with warm water. If water is allowed to stand in the sink, water stains and streaks will occur.
Cover the entire surface of your sink with a non-abrasive stainless steel cleaner such as Soft Scrub, Bar Keepers Friend Cameo or stainless steel cleaner. Scrub and rinse with warm water and dry with a paper towel. Doing this once a week as preventative maintenance can help prevent stains and rust buildup.
Apply white vinegar on a cloth and clean the sink clean. This will clean and polish your sink. You can also remove the streaks by rubbing the olive oil in the sink. Scratches can occur over time due to covered tools and cooking utensils being placed in the sink.
