Janitorial dilution calculators
Standardise spray bottles, mop buckets, and sanitizer batches for custodial teams with mix math that scales from 32 oz bottles to 5 L sprayers.
These janitorial presets target the most common cleaning ratios used by custodial crews—heavy 1:16 degreasers, 1:32 general cleaners, 1:64 neutral floor products, and 500–1000 ppm sanitizer mixes.
Each calculator opens the MixByParts modal with your target bottle or bucket size preloaded. Adjust totals for bigger batches, flip to weight mode when you have density data, and copy ready-to-print labels for compliance logs.
Bleach-based sanitizer presets flag PPPM targets so you can document food-contact or high-touch disinfection without re-running manual math.
Popular use cases
- Fill 1:32 restroom spray bottles across a custodial cart
- Batch 1:64 neutral floor cleaner into gallon refill jugs
- Mix 500 ppm sanitizer in a labelled gallon jug for food-contact surfaces
Prep a janitorial batch
Launch the mixer with a 1:64 neutral cleaner in a 1 gallon jug. Adjust the ratio for restroom deep cleans or flip to ppm mode for sanitizer logs.
Defaults: 1 gallon total, 1 part product to 64 parts water.

FAQs
What is the difference between 1:32 and 1:64 for daily cleaning?
1:32 keeps more concentrate in the mix and suits restroom and heavy soil areas. 1:64 is a lighter neutral ratio ideal for finished floors or glass. The calculators surface both so you can standardise per surface.
How often should bleach sanitizer batches be replaced?
Most health departments require 500 ppm sanitizer to be replaced every 24 hours (or sooner if visibly soiled). The ppm presets make it easy to document fresh batches each shift.
Can I scale these ratios to auto-scrubbers or pump sprayers?
Yes. Change the total volume to match your equipment (e.g., 3 gal auto-scrubber tank or 5 L pump sprayer) and the tool recalculates product and water instantly.
