Product Overview
Sulfuric acid is a highly concentrated, heavy liquid chemical that plays a pivotal role in industrial maintenance and chemical processing. Our Drain Hammer formulation features a 93% concentration of active sulfuric acid, delivering rapid action for demanding commercial drain-clearing operations and industrial neutralization tasks. Because it is highly hygroscopic and dense, this substance quickly sinks through standing water to target blockage areas directly, initiating an exothermic reaction that breaks down organic materials, grease, hair, and soap scum. We deliver this product in multiple packaging sizes to suit facility requirements.
As a premier Texas chemical distributor, Alliance Chemical ensures that our commercial drain cleaning formulations meet strict quality benchmarks. The 93% concentration is highly effective at charring wood, paper, and other organic matter on contact without initiating immediate combustion, utilizing its dehydrating properties to degrade tough blockages. Facility managers and industrial operators rely on this technical-strength fluid for routine maintenance of heavy-duty drain networks, commercial kitchens, and industrial processing systems. By sourcing direct from Alliance Chemical, clients receive a reliable, high-purity supply.
Why This Grade
Industrial processes require precise concentration controls to prevent operational failure and ensure system integrity. This 93% concentration of sulfuric acid, which carries no specific analytical grade designation — grade is not applicable — is specifically chosen because it offers the optimal balance of raw power and chemical stability. Sourcing an incorrect concentration, such as a lower dilute acid, often fails to generate the necessary heat of dilution required to melt stubborn grease blockages, rendering the clearing process ineffective and leaving standing water contaminated with weak corrosive compounds.
Conversely, utilizing a 98% concentration in standard plumbing lines can introduce excessive thermal stress, potentially warping or damaging PVC pipework due to uncontrolled exothermic release. Furthermore, using a grade with excessive trace metallic impurities can lead to side reactions and premature degradation of transport equipment. For demanding industrial applications and pH neutralization systems, our 93% concentration ensures predictable reaction kinetics, reducing the risk of equipment failure, safety hazards, and incomplete material degradation.

- Appearance
- Sulfuric acid is a colorless oily liquid. It is soluble in water with release of heat. It is corrosive to metals and tissue. It will char wood and most other organic matter on contact, but is unlikely to cause a fire. Density 15 lb / gal. Long term exposure to low concentrations or short term exposure to high concentrations can result in adverse health effects from inhalation. It is used to make fertilizers and other chemicals, in petroleum refining, in iron and steel production, and for many other uses. Rate of onset: Immediate Persistence: Hours, days Odor threshold: Source/use/other hazard: Battery/dyes/paper/glue/metals industries; volcanic gas; toxic fumes when heated.

Industrial Applications
- Drain clearing and organic material degradation in commercial plumbing, high-volume industrial waste lines, and municipal sewer systems where grease build-up occurs.
- pH adjustment and wastewater treatment protocols to neutralize alkaline effluent streams in chemical manufacturing facilities, ensuring compliance with local environmental discharge regulations.
- Industrial chemical synthesis and manufacturing where sulfuric acid acts as a reactant, catalyst, or dehydrating agent in producing chemical intermediates.
- Lead-acid battery electrolyte replenishment and maintenance in automotive, aerospace, and industrial backup power systems requiring high-purity acidic solutions.
- Metal pickling and descaling operations to remove rust, oxides, and scale from iron, steel, and other metallic surfaces before coating.
Hazmat & Shipping
As a regulated hazardous material, this product is subject to strict transport and handling protocols. It is classified under United Nations regulations as UN1830, Hazard Class 8 (Corrosive), Packing Group II, with the proper shipping name SULFURIC ACID WITH MORE THAN 51 PERCENT ACID. The assigned signal word is Danger, and its primary hazardous characteristic is marked by hazard statement H314, indicating that it causes severe skin burns and eye damage. Alliance Chemical coordinates all freight logistics in full compliance with DOT 49 CFR requirements to ensure safe transit of this highly corrosive mineral acid.
Due to the severity of GHS hazard statement H314, personnel must wear comprehensive personal protective equipment (PPE) during any transfer or application. This includes acid-resistant neoprene or nitrile gloves, a complete face shield, chemical splash goggles, and a heavy-duty protective apron. In the event of exposure, immediate action must be taken in accordance with the precautionary statements, such as P260, P264, P280, P301+P330+P331, P302+P361+P354, P304+P340, P305+P354+P338, P316, P321, P363, P405, and P501. Proper safety protocols and spill containment measures must be established prior to receiving this material.
Handling & Storage
Store sulfuric acid in its original container or compatible high-density polyethylene (HDPE) vessels, ensuring the containers remain tightly closed in a cool, dry, well-ventilated area away from direct sunlight. Maintain storage temperatures above its melting point of 50.65 °F to prevent crystallization, while avoiding extreme heat that could increase vapor pressure. Sulfuric acid is highly incompatible with strong bases, water — always add acid to water slowly, never water to acid — organic compounds, and active metals, as contact can produce hazardous hydrogen gas.
