Descaler for all steam irons and press systems. 
Dissolve one cap of cleaner with a ratio of 5 caps of water and place it inside the iron.
Then wait for the iron to heat up, release all the steam, and wipe the iron plate with a dry and clean cloth.
When you finish cleaning, place clean water in the iron to rinse any cleaner residues that may have remained in the steam tube of the iron.
