Malic acid can be used to clean a variety of metals because it is gentle. A solution of malic acid will clean pennies.
It is also suitable for cleaning stainless and other carbon- steel as it will not stress or crack the alloy. This makes it very handy for cleaning the heating filament in kettles, too (and you can trust me on this, because I've actually done it several times).

What apples are the lowest in malic acid content?
The least sour apples are lowest in malic acid content. As a rule, of all the acid present in apples, 90 - 98% of it is malic acid. The acid gives the apple a sour but fresh, clean taste. New green apples tend to have more bite than red apples, so it is likely that they contain the least malic acid.
What is differnece in dl-malic acid and malic acid?
There are two different structures of malic acid, an L-isomer and a D-isomer. These two molecules are identical like your left and right hands. While they have the same atoms and bonds, they are not necessarily interchangeable, just as you cannot fit your left hand in a right hand-shaped hole. L-Malic acid is produced naturally in fruits. 90% of the acid in apples is malic acid. When malic acid is produced synthetically, a mixture of the two isomers is obtained which is called DL-malic acid (because it contains both D- and L-malic acid). When you eat DL-malic acid, your body digests the L-malic acid normally (it is part of the Kreb's cycle), but the D-malic acid is excreted in the urine. A 1967 study by the WHO shows evidence that D-malic acid is toxic and causes renal damage. When purchasing malic acid, if it is called "malic acid" it is likely DL-malic acid. If the natural form is desired, purchase specifically L-malic acid.

acid
Do apples contain malic acid?
Of all the acid in green apples, 90% of it will be malic acid. This naturally-occuring acid will be found exclusively in the form of the L-isomer, whereas synthetic malic acid is made up of both L- and D-malic acid
What acid is present in apple?
Malic acid, also shown as E296 when used as an additive ingredient

What kind of acid is best to clean pennies?
Hydrochloric Acid
What is difference in malic acid and dl malic acid?
There are two different structures of malic acid, an L-isomer and a D-isomer. The only difference between the two is that they rotate the light shining on them in two different directions. L-Malic acid is produced naturally in fruits. 90% of the acid in apples is malic acid. When malic acid is produced synthetically, a mixture of the two isomers is obtained which is called DL-malic acid (because it contains both D- and L-malic acid). When you eat DL-malic acid, your body digests it in just the same way as it does for L-malic acid. It is part of the Krebs cycle.

acid
What fruit has the most malic acid?
Apples contain the most malic acid as a percentage of total fruit acid content. The amount of malic acid in apples as a percentage of the total acid is 94-98%
Is malic acid a natural product?
There are two forms of malic acid; the L-isomer is found naturally in most fruits and many vegetables in varying amounts. Of the total acid content in apples, 90-98% is L-malic acid. Malic acid can also be produced synthetically from maleic anhydride. It is impossible to choose whether natural L-malic acid or the unnatural D-malic acid isomer is formed during synthesis so a mixture of the two is formed, often called DL-malic acid. It is most likely that if malic acid is used as an additive, it is the synthetic DL-malic acid. The body metabolises the two forms in exactly the same way.
Where is malic acid found?
Malic Acid is found in mostly green apples, grapes and wine .
