If that doesnt work, you may need to call a professional. You can neutralize small spills (100 mL or less) by covering with magnesium sulfate (dry) and absorbing with spill control pads or other absorbent materials. You must have the right personal protective equipment, including, at a minimum, appropriate eye protection, protective gloves, and a lab coat. Baking soda is pure sodium bicarbonate, a fine white powder that has many uses. While some hazardous substances have RQs as low as one pound, typical RQs are larger than the amounts found in laboratories. Available in concentrations ranging from 10% to 98% sulfuric is also the least expensive acid to use as a neutralizing agent.
