product composed of very fine abrasives and polishing brick. It is particularly suitable for the systematic removal of medium-light corrosion stains (not perceptible to the touch) on shiny marble surfaces. The product is also valid for severe corrosion as long as you have a #1000 grit abrasive (not included in the kit) to use in the initial phase of the treatment.
The polishing restoration intervention is limited to the area of the opaque stain, without consequences for the homogeneity of the surface shine.
