WHAT IS IT?

12.5% Sodium Hypochlorite (SH) is the industry standard for professional exterior cleaning. It is the active ingredient responsible for killing mold, mildew, algae, moss, bacteria, and other organic contaminants on roofs, siding, concrete, fences, and many exterior surfaces.

Unlike household bleach (typically 5-8%), professional-grade 12.5% SH provides significantly more cleaning power, making it the preferred choice for soft washing contractors.

💀 TSS PRO TIPS

• Fresh bleach cleans better than old bleach.
• Heat and sunlight are SH's biggest enemies. Keep it cool and shaded.
• Let chemistry do the work. More dwell time usually beats stronger mixes.
• Always verify downstream injector's draw rate before adjusting chemical strength.
• Healthy landscaping starts neutralizing SH with TSS's NeurtraPods, which makes it quick and easy. Always do proper pre-wetting, whether or not you'r using NeutraPods, and thorough rinsing after application.
