Know what's in the jug before you mix it

An SDS is a regulatory disclosure document — it tells you everything the manufacturer is required to tell you, in a format designed for lawyers. This guide translates what matters in Sections 2, 8, and 9 into field decisions: what PPE to wear, what not to mix it with, and what to do if exposure happens. SDS sheets don't tell you how to dilute for different surface types or how storage temperature affects your 12.5% SH.

Yes — SH is the primary chemical. The guide covers SH concentration decay by temperature and age, correct dilution math for residential vs. commercial vs. soft-wash applications, surfactant compatibility, and neutralization before discharge.

Yes. The surfactant section includes a 15-surfactant selection matrix across 6 surface categories, mixing behavior with SH, and how surfactant concentration affects runoff compliance.

Yes. Chemical incompatibility, PPE requirements, and emergency response are federal (OSHA) standards that apply everywhere. The disposal section includes nationwide guidance first and then CA-specific stormwater rules as a supplement.

Yes — sodium percarbonate is included in the incompatibility matrix (it reacts with acids and some organic materials), the PPE lookup, and the disposal guide. Soft-wash operators using it as an alternative to SH will find this directly applicable.
