53G516 - Walter SC 400 Natural Heavy-Duty Citrus Degreaser - 3.78L Jug

The Welder's Choice for Tough Shop Grime

Keep your metal prep and cleanup operations running smoothly with Walter SC 400™. Every welder knows that a clean surface is the foundation of a good weld, and sometimes, standard soap and water just won't cut it. This 1-gallon jug of high-strength cleaner and degreaser is your go-to solution for removing the heavy, sticky, and oily messes that accumulate in a busy fabrication shop. Whether you are dealing with shipping oils on new steel, stubborn anti-spatter residue, or old adhesive from labels, SC 400 powers through it all using the natural strength of citrus.

Unlike harsh chemical solvents that fill your shop with toxic fumes, SC 400 utilizes natural citrus peel extracts to dissolve contaminants. It smells better and is safer for the environment, being fully biodegradable. However, don't let the "natural" label fool you—this stuff is aggressive. It quickly breaks down tar, rubber residue, sealants, and heavy lubricants on machine parts, tools, pumps, and gears. It is an excellent choice for cleaning up equipment during maintenance or prepping metal stock before it hits the welding table.

One of the practical benefits for the workshop is the product's slow evaporation rate. Many solvents flash off too quickly, requiring you to reapply constantly. SC 400 stays wet longer, giving the solution time to soak into the grime and lift it away effectively. It also has a higher flashpoint (113ºF) than many comparable solvents, adding a layer of safety to your flammable storage cabinet. Simply pour some into a sprayer or onto a rag, apply it to the metal surface, and watch the grease dissolve.

Applications in the Shop

Use SC 400 to clean up your welding jigs, remove protective waxy coatings from new materials, or degrease machinery gears and chains. It is also a lifesaver for removing those annoying paint marker lines or ink stains from finished pieces. Just remember: this is a potent solvent for metal. Keep it away from plastic handles, rubber hoses, and gaskets to prevent damage. With the 3.78 L jug, you have plenty of supply to keep your shop clean and efficient.
