1. General-Purpose Detergent

2. Degreaser

• What It Is: A powerful cleaner designed to dissolve grease, oil, and heavy grime.

• Why It’s Effective: Essential for tough jobs like driveways, garage floors, or machinery, where oil stains resist regular cleaners. It cuts through grime quickly, saving time.

• How to Use It Safely: Follow dilution guidelines, typically 1 part degreaser to 5–10 parts water. Spray on with low pressure, let it penetrate for 5–10 minutes, and rinse with high flow. Wear protective clothing, gloves, and goggles, as degreasers can irritate skin or eyes. Avoid delicate surfaces like wood or painted areas, and test first.
