Dry-Treat HANAFIN Eff-Erayza - Efflorescence Remover

Dry-Treat Eff-Erayza™ is a new technology acid cleaner for removing efflorescence, rust stains, limescale, grout haze, mortar mess and fireplace soot. Eff-Erayza™ is very powerful and generally more effective and safer to use than traditional industrial acids but does not produce noxious fumes, non-corrosive to metals (except for uncoated aluminium) and temporary contact does not burn skin.

Typical Applications
  • Eff-Erayza™ is an acidic cleaner for removing mineral residues including, efflorescence, grout haze, rust marks, limescale & mortar mess
  • Eff-Erayza™ does not produce noxious fumes so it can be used indoors and outdoors
  • Suitable for commercial & domestic use on floors, walls, facades, showers, masonry, brickwork, patios, driveways, garage floors.
  • Eff-Erayza™ is suitable for a wide range of non-acid sensitive stones and other hard surfaces, including, granite, slate, basalt, brick, glass, ceramic and porcelain tile, terracotta.
  • Acidic cleaners are commonly used to clean paving & poured concrete surfaces. If using Eff-Erayza™ on concrete or other cementitious surfaces, neutralise the surface as soon as possible after cleaning to minimize etching, with something alkaline, such as Oxy-Klenza dissolved in water, then rinse thoroughly with fresh water.
  • Effective for etching marble, limestone & other acid sensitive stones to achieve a 'honed' (matt) finish
  • WARNING: Eff-Erayza™ is acidic and will etch / damage acid sensitive stones such as marble, limestone, travertine and onyx as well as concrete / grout products and uncoated aluminium. Read all of the safety directions and precautions carefully before using.
