How Do I Clean The Bottom Of The Pan?
Swiss Diamond products are made of cast aluminum for its superior heat transfer and strength. On Swiss Diamond Classic pans, the aluminum base is trimmed and left uncoated for a brilliant shine. When cleaned and polished, it has a beautiful appearance! To keep the base of your pan looking like new, follow these simple steps for cleaning uncoated aluminum.
First, avoid the dishwasher. To preserve the shine of the aluminum base, do not put your Swiss Diamond cookware in the dishwasher; harsh, abrasive dishwashing detergents dull the metal’s shine. Please note: this is only an aesthetic issue; Swiss Diamond cookware is dishwasher safe.
Second, remove any food residue. Aluminum is a relatively soft metal, which means it can scratch or scuff more easily than the nonstick coating of Swiss Diamond pans. It is not recommended to use abrasive scouring pads on uncoated aluminum, as these can create deep scratches. To remove food residue and other build-up, apply a paste of baking soda and water about the consistency of toothpaste. Allow it to sit for 15 minutes, then scrub gently with a soft sponge or washcloth. If the baking soda is not strong enough, Bar Keepers Friend is an excellent alternative. Choose a non-abrasive scouring pad, such as a synthetic mesh scrubbie or a bristle brush, rather than a Brillo pad or steel wool – these can create deep scratches in the aluminum.
A less labor-intensive method, recommended by one of our customers, is to apply a layer of baking soda to the base of the pan, gently pour hydrogen peroxide over the top, and top with another layer of baking soda. Allow to sit for 30 minutes to several hours, depending on the level of cleaning needed. The same method can be used to renew old cookie sheets and baking pans, as shown in this photo below.
The food residue does not need to completely disappear in this step; you will follow with additional cleaning methods. However, removing thick build-up and food particles allows the next step(s) to penetrate all the way to the aluminum base.
Next, remove any grey discoloration with a vinegar solution. In a large bowl, mix 1 part vinegar : 2 parts hot water. Immerse the Swiss Diamond pan in the solution for 15 minutes; check to see if the discoloration has disappeared by scrubbing gently with a soapy sponge, cloth, or non-abrasive cleaning pad. Continue soaking in the solution until the desired result is achieved.
If the base is extremely discolored, a stronger solution may be used. Try to avoid instances of the solution remaining on the nonstick exterior of the pan, as it could eventually cause aesthetic damage. Create a solution of 1 tablespoon cream of tartar or lemon juice : 1 quart (1 liter) water. Heat on the stove in a different pan until it comes to a simmer. Wearing rubber gloves, immerse the base of the discolored pan in the solution. Follow with a baking soda paste, as described in step two. Repeat as needed to remove discoloration.
Finally, repeat the baking soda scrub and rinse thoroughly with dish soap to remove any remaining cleanser. Your aluminum base should be as good as new!
