Corrosion Block in this case of 12 supplies 12 separate 12 oz aerosol cans. This listing is SKU 76733, listed case code 20012CASE. Twelve 12 oz aerosol cans for maintenance teams comparing aerosol case quantities. Choose the formula by its intended maintenance role before comparing purchase quantity and the way it is dispensed.

Corrosion Block is a penetrating corrosion-inhibiting fluid that leaves a thin protective barrier on suitable surfaces. Manufacturer application literature describes spray, brush and wipe methods and identifies metal and electrical-component applications. Select the treatment by the actual component and its approved maintenance procedure before choosing how much supply to order. A protective film does not establish that a deteriorated part is safe to keep in service.

The case includes 12 separate containers, each labeled 12 oz. One cart unit is the full case, not one pictured bottle or can. This format lets a maintenance program distribute identified product between work locations while keeping the individual container instructions available. Compare the single-container option if a smaller purchase fits your needs; buying a case does not change the amount appropriate for one application.

For compatible metal and approved electrical-component locations. Confirm coatings, plastics, seals and equipment requirements; isolate electrical power before servicing. Inspect the treated or cleaned area during regular maintenance. Surface condition, exposure and the equipment’s requirements determine whether more cleaning, protection or physical service is needed. Compare related products by role and compatibility before judging nominal package size.
