11. Cleaning
11.1 Maintenance and preservation of stainless steel:
Do not use chemical products, bleaches, or household cleaning products.
Routine cleaning
: The best products to preserve stainless steel are water, soap, mild
and neutral detergents and ammonia-based removers diluted in warm water and
applied with a soft cloth or a nylon sponge. Then, rinse with plenty of water, preferably
warm, and dry with a soft cloth.
Fat, Oil, and Grease : Clean thick deposits with a soft cloth or a paper towel. Then,
apply a warm solution of water and detergent or ammonia. After, follow the routine
cleaning procedure.
Finger marks : Remove them with a soft cloth or paper towel dampened with isopropyl
alcohol (found at manipulation pharmacies) or organic solvent (ether, benzene).
Labels, tags, and films
: Remove all that you can. Apply warm water over the piece
and scrub it with a soft cloth. If the adhesive remains, dry it and then scrub it again
lightly with alcohol or organic solvent. Be careful: never scrape the stainless steel
surface with blades, spatulas, or rough abrasives.
Rust stains : with a cotton swab moistened with water and nitric acid (10%), apply
topically, maintaining the place humid for 20 or 30 minutes, repeating the operation if
necessary.
Stains that are more prominent will demand a vigorous scrub of the stained surface
with a paste made of fine domestic abrasive, water and nitric acid (10%) using a
polishing loofah.
The treatment with acid must always be followed by rinsing with ammonia or bicarb
soda solution and of the routine cleaning.
Light dirt/light stains: When the routine cleaning is not enough, apply a mixture
made of plaster or bicarb soda dissolved in domestic alcohol until a paste forms. Use a
soft cloth or nylon loofah to spread the mixture on the stainless steel surface. If you
prefer, also use a soft brush, being careful not to brush, but processing as lightly as you
can, using long and uniform strokes in the direction of the polishing, if there is any.
Avoid rubbing in circular movements.
Then, rinse it with plenty of water, preferably warm, and dry it with a soft cloth.
