It can be a real pain to remove it.  It's an incredibly strong bond.  Using a pumice stone requires a lot of effort and can ulitimately scratch tile glaze, remove grout, and even remove painted numbers.  And still, there will be some scale left on the surface that isn't obvious  but will cause your tiles to have a dull finish.

Likewise, muriatic  acid (hydrochlric acid) or other strong acid products CAN DULL your tile's glazing and remove grout over time.

Guardian Pool & Tile Cleaner BREAKS THE BOND between the scale and surface rather than removing it by force with a hard stone.   

Removing scale build up with a pumice stone or other mechanical means can take A REALLY LONG TIME!!!   Your time.  

Sure, acid will remove scale on your tiles & surfaces, and it's CHEAP.    But as they say, there's NO FREE LUNCH.  What is saved by using a cheaper product may be MORE COSTLY in the end.    Tile glazing and grout can be damaged over time and these kinds of products can cause burns and other injuries to you. 

Guardian Pool & Tile Cleaner is made from natural elements & has NO HARSH ACID.

WHICH MEANS IT WON'T BURN YOU or DAMAGE YOUR TILES/GROUT/OTHER SURFACES like metal ladders.
