Product Overview

The Acid Spill Neutralizer Socks is a dual-action acid spill response sock that absorbs AND neutralizes acid spills on contact. Each sock contains a proprietary AcidSafe neutralizing filler (sodium carbonate-based) inside a chemically resistant fabric shell. The purple filler features a built-in pH color-change indicator -- turning dark gold on contact with strong acids and yellow/orange for mild acids -- providing visual confirmation when neutralization is complete. The flexible tube design allows you to surround battery racks, line acid storage shelving, and create containment barriers around acid-handling equipment. Ideal for battery charging stations, acid storage rooms, laboratories, and any facility handling sulfuric, nitric, or phosphoric acid. Not for use with hydrofluoric acid (HF) or HF compounds. Backed by AbsorbentsOnline -- trusted since 1985. Ships FREE to the Continental US.

Expert Insights

With 40+ years of industrial supply experience, AbsorbentsOnline recommends AcidSafe neutralizer products for any facility handling battery acid or corrosive chemicals. The dual-action formula absorbs AND neutralizes in a single step -- eliminating the need to first contain a spill with standard absorbents and then apply a separate neutralizing agent. The built-in pH color-change indicator is a significant safety advantage: purple filler turns dark gold on contact with strong acids, yellow/orange for mild acids, and returns to purple when neutralization is complete. This visual confirmation eliminates the need for pH paper testing during an active spill event. Pro Tip: Pre-position acid neutralizer products at every battery charging station, acid storage rack, and laboratory acid cabinet. In an acid spill, the first 60 seconds of response determine whether it's a minor cleanup or a major incident.

Acid Spill Neutralizer Socks | Industrial Absorbent Sock

Why Industrial Absorbent Socks Are Essential

Industrial absorbent socks are flexible, tubular absorbents engineered to contain and absorb spills in areas where flat pads and rolls can't conform — around machinery bases, equipment legs, pipe flanges, along trench drains, and across doorways. Their 3″ diameter tube design creates an effective physical barrier to prevent liquid spread while simultaneously absorbing the contained fluid, making them the ideal solution for perimeter containment, drip lines, and active leak management.

Engineered for Your Application

This acid neutralizer sock is a dual-action spill response product that absorbs AND neutralizes acid spills on contact. The proprietary AcidSafe filler contains a sodium carbonate–based neutralizing agent with a built-in pH color-change indicator — purple filler turns dark gold on contact with strong acids and yellow/orange for mild acids.

Purpose-built for battery charging stations, acid storage rooms, laboratories, and any facility handling sulfuric, nitric, or phosphoric acid. The flexible tube design allows you to surround battery racks and create containment barriers. Not for use with hydrofluoric acid (HF).

Supports Regulatory Compliance

This absorbent sock supports compliance with the following regulations:

  • EPA 40 CFR 112.7(c)(1) — SPCC Plans require facilities storing oil to maintain adequate containment and cleanup materials on-site.
  • OSHA 29 CFR 1910.22(a)(2) — Walking-working surfaces must be kept clean, dry, and free of hazards including oil and fluid accumulation.
  • EPA 40 CFR 122.26 — NPDES Stormwater Management requires prevention of oil and pollutant discharge to storm drains and waterways.
  • State Environmental Regulations — Most states require facilities to prevent petroleum and chemical contamination of soil, groundwater, and surface water.

What Our Customers Say

Real reviews from the facilities, field crews, and agencies that count on us.

  • We wrap these socks around the base of every CNC machine on our floor. They conform perfectly around the equipment legs and catch coolant and oil before it reaches the walkways. Way more practical than trying to use flat pads in tight spaces. The 8-foot length covers an entire machine perimeter without gaps.

    Mike R. — Maintenance Lead, CNC Machine Shop

    Verified Buyer
  • Our SPCC inspector specifically recommended absorbent socks for our outdoor transformer pads. We line them across the secondary containment entrance and they keep oil from migrating to the stormwater drain. These hold more fluid than the brand-name socks we used before, and the price per case is much better.

    Karen S. — Environmental Compliance Officer, Power Utility

    Verified Buyer
  • We keep a case of these socks on every emergency spill cart. When someone reports a leak, the first thing we do is surround the spill with socks to contain it. They mold right around pipe flanges and equipment legs — places where pads just slide off. The free shipping from AbsorbentsOnline saves us a fortune compared to our old industrial supply vendor.
