Systematic Dry Cleaning for the Preservation of Monuments, for Paintings, and for Artistic Objects with Diverse Surfaces.

The abrasive dry cleaning block – gentle and able to be cut to size


within the aka-product system, akabloc is appropriate for cleaning heavy soiling on materials which are not highly sensitive, such as wood, stone, or metal. As compared to the classic products, the akabloc product line – with its higher level of abrasion – is still able to clean heavy soiling on hard surfaces gently. Depending on the degree of soiling, one can use either akabloc abrasive chalk or akabloc AX-O-Blanc. The akabloc abrasive products are available both as plates or as blocks.
