                   When  cleaning  everything  in  the  house,  whether  it's  clothes,  toilets,
             floors,  glass,  etc.,  you  usually  rely  on  special  cleaning  products  from
             various brands. What happens when you clean porcelain and ceramics
             using materials aforementioned? Surely the porcelain and ceramics that

             you  clean  will  be  sleek  and  clean,  right?  Did  you  know  porcelain  and
             ceramic cleaners contain acid, namely hydrochloric acid (HCI) which is a
             strong  acid  so  that  it  can  make  the  moss  scale  on  porcelain  and
             ceramics lifted and can even damage the ceramics.

                   Some acid and base compounds are safe if they come into contact

             with  hands,  even  some  types  of  acidic  compounds  are  used  in  the
             manufacture  of  foods  such  as  vinegar  acid.  Likewise  with  alkaline
             compounds, for example soap used for bathing is a compound that is
             safe if it comes into contact with the skin. However, some other types of

             acids or bases can cause burning if they come into contact with hands
             or skin. This difference in properties is due to the strength of the acid and
             base compounds vary.
