Glass or enameled ceramic dishes, glasses, goblets, glass mugs and especially cutlery, can suffer the signs of deterioration over the years and improper washing, especially when the wash waters are hard (rich in lime) and we have used aggressive detergents, as is the case with dishwashers.
Wash dishes and pots: hot or cold water, by hand or with a dishwasher?
In this case, not even using brightener in this last device we achieve the brightness that they had in the beginning. The reason? It's very simple: lime, grease stains and rust they can leave a mark on your surfaces that sometimes seems indelible, although it may not be. Lime and grease kill shine and are not easily removed with a normal detergent no matter how hard we scrub.
When it comes to rust, it blackens our stainless steel cutlery because the steel contains 10% to 12% chromium, which is what really protects against iron oxidation. This layer of chromium, known as the "passivating layer" does have a great affinity for oxygen and darkens when reacting with it. And the same happens with silver cutlery, which darkens with time in contact with oxygen.
Restore shine to glasses and plates
Making it clear that any loss of gloss related to abrasion by detergents, scratches or excessively hot water cannot be totally reversed, there is always room for improvement if we take into account that removal of lime of the surface of the plate will help greatly. To do this, we must first make sure that any incrustation of fat and food remains are removed.
In a basin, or in the sink of the sink, we will leave throughout the night the plates, cups, glasses and glasses that we want to recover with warm water with a dishwasher jet. The next day we will remove them one by one and dry with kitchen paper, so that all the remains are eliminated.
Once this operation has been carried out, we will proceed to transfer them to another basin with water in solution of White vinegar -the normal should be avoided due to possible staining- and salt. We will leave them soaked for one to two hours and then we will proceed to dry them with kitchen paper, rubbing a little to gain shine.
Lighten the color of the cutlery
To lighten the color of the cutlery we will practice a very similar operation, although with some variations at the end. The first step will be, again, to ensure the elimination of any remaining food or fat attached to the surface. To do this, we will leave the cutlery to soak overnight in warm soapy water.
The next day we will take out the cutlery one by one and dry them with a dry cloth or kitchen paper. Then, to recover its scratch-free appearance, we will smear all the pieces in olive oil We will rub vigorously again with a dry cloth or kitchen paper, until they completely lose their oily touch.
Next, in the case of silver cutlery, we will sprinkle them with a baking soda paste and water, ensuring that they are well coated, and then dry them vigorously with a dry cloth, eliminating the bicarbonate and with it possible remains of stains and oxides that darken the surface.
In the case of stainless steel cutlery it is more effective use white vinegar what bicarbonate. To do this, we must pass each piece through a cloth soaked in white vinegar, rubbing hard for a while, and then dry them with another cloth, so that we remove the lime and recover the maximum shine.
