View all our products
Acid-free cement residue and dirt remover

Seal-Guard® All Clean is a powerful, mildly alkaline, solvent-free cleaner, consisting of a balanced combination of dirt-dissolving and cleaning components. Suitable for cleaning dirty stone surfaces, both old and new. Seal-Guard® All Clean has been developed to remove minor grout haze, limescale, oil and grease, floor-care product residue and general dirt.


Seal-Guard® All Clean can be applied to all types of polished, grinded or rough stone surfaces, including natural stone, such as granite, slate, sandstone and quartzite, as well as terrazzo, concrete stone, porcelain stoneware, (glazed) ceramic tiles, terracotta, etc. Because Seal-Guard® All Clean is acid-free, it can also be applied to types of natural calcareous stone, such as marble, travertine, limestone, bluestone and basalt. Seal-Guard® All Clean binds to limescale and will not damage your surfaces. Suitable for indoor and outdoor use.


Dilute with water in a 1:2 to 1:10 ratio, depending on your cleaning needs.

Directions for use

Try the product in an inconspicuous spot first to determine its suitability for the intended use. Moisten the surface to be cleaned with water beforehand. Apply the diluted Seal-Guard® All Clean and spread over the surface with a brush or pad. Leave for 5 to 10 minutes, but do not allow to dry, before scrubbing thoroughly. Finally, rinse thoroughly with clean water. For the best results, apply Seal-Guard® All Clean within 24 hours after the grout has dried. To remove even the most stubborn dirt, repeat the same procedure on a dry surface.


Approximately 10 to 30 m2 per litre of Seal-Guard® All Clean, depending on the degree of soiling.


Available in 1-litre containers (12 x 1 litre per box).


Keep only in the original, tightly closed container in a cool, well-ventilated place. Do not allow to freeze.
