When are they used?
Cleaning of water-sensitive (painted) surfaces is a very delicate operation, since detergent systems have to
perform a selective and controlled action to remove grime, dirt and/or aged varnishes without
affecting the original materials and/or the underlying pictorial layer. Gels are usually used for this purpose. Traditional gelled systems
offer quite good performances, but their nature makes them very hard to be removed from the
cleaned surface and might produce irreversible damages to the pictorial layer. Nanorestore Gels® Dry are designed to overcome the limits of traditional gels.
How do they work?
They are used as vehicle (containers) for the liquid cleaning agent. They prevent the
liquid from fast evaporation and uncontrolled penetration into porous materials making
the cleaning safer. Moreover, thanks to their formulation they do not leave residues on the treated surfaces.
How are they used?
The transparent gels are used as loaded with water, aqueous solutions, several
solvents or water-based nanostructured fluids of the Nanorestore Cleaning®
series. The loaded gel is applied over the
surface, and the undesired layers (dirt, grime, aged varnishes, adhesives etc.)
are either dissolved (and migrate into the gel) or swollen/softened and removed
by gentle mechanical action directly after the removal of the gel form the surface.
