Hydra HDC-76 removes foul odour producing bacteria with its powerful cleaning action. An effective water descaler, Hydra HDC-76 cleans and deodourises simultaneously. This multi-action formula eliminates the need to use multiple products for cleaning.

Hydra HDC-76 does not fume excessively; therefore is suitable to work within confined areas. Low foaming action ensures easy rinsing off.

Uric salts, present in urine, as well as calcium/magnesium carbonates, are the primary cause of scaling. These depositions create a bad odour and may choke drains and traps. Hydra HDC-76 fixes these problems. 


Not suitable for use on stainless steel surfaces.

Not suitable for Klargester Ecological Septic Tanks. 

Do not mix HDC-76 with other cleaning agents or chemicals such as bleach or acids.

How To Use

  • Pour onto the scale deposits or stains directly. Allow contact time while HDC 76 dissolves scale deposits.
  • Once the scaling loosens and comes off the surface, flush the toilet.
