TASCO/Rittel's Saftee-Acid is one of the safest acids available today! It provides a wide range of acidity, with none of the disadvantages of other acids, such as, sulphuric/formic/acetic/oxalic! It is practically odorless, with no caustic fumes, non-poisonous, no dilution heat, non-evaporative, and is an excellent choice for pickling as well as adjusting PH levels! We have experimented considerably with this acid, and have found that using it has lived up to all our expectations! Since it is non-hazardous, it is safe to ship anywhere, and because of it's low dosage - it actually saves money!
