Chalk is primarily composed calcium carbonate, CaCO3. Carbonates are typically not very soluble in pure water or basic solutions, but tend to be very soluble in acidic solutions. One household item that would be useful for cleaning up chalk would be white vinegar, which is acetic acid, HCH3CO2. The acetic acid would react with the calcium carbonate to produce calcium acetate, water and carbon dioxide. CaCO3 + 2HCH3CO2 > Ca(CH3CO2)2 + H2O + CO2 The calcium acetate is soluble in water, so it would not be visible.
