Poorboys Spray and Rinse or CG Grime Reaper?

Use caution with this product - Sodium hydroxide (NaOH), also known as lye and caustic soda, it's a corrosive alkaline (pH 13.5 on an alkaline scale of 14) substance (a caustic metallic base). Sodium hydroxide forms a strong alkaline solution when dissolved in a solvent such as water.
