Specialty cleaning products have a narrower spectrum of uses than all-purpose products. They are designed for specific surfaces, such as glass, bathroom surfaces, ovens, drains, metal, floors, carpets, furniture and upholstery, and the soils that usually collect on these surfaces. By concentrating on specific conditions, specialty products can deliver optimum performance and convenience.

Automobile engines have many moving parts. As these parts move and rub against each other, the force of friction creates heat. Oil lubricates the engine and absorbs heat, allowing the internal parts to work together effectively without overheating. Over time, engine oil breaks down and wears out.
