Batch Mix

Batch-Mix is a local-first utility for pressure-washing and soft-washing field work. Enter your batch size, source strength, and target strength to estimate SH and water amounts in gallons or liters. Save mixes with notes on the device, add an optional Surfactant Helper while preserving final batch size, and use the downstream tool to estimate applied strength after an injector.

The free app includes the Basic SH/water calculator, unit switching, saved mixes, and limited Surfactant Helper uses. Batch-Mix Pro adds the Field Guide, Advanced Mode, and continued Surfactant Helper access after the free allowance. Subscriptions are optional and managed by the App Store. Any introductory offer is shown only when the store confirms eligibility.

Batch-Mix provides estimates and general reference information. It is not a guarantee of cleaning results, a chemical label, or a replacement for product labels, SDS, equipment instructions, local requirements, and testing a small area first.
