Chemical Dilution, Labeling & Surface Matching: the full procedure

Dilute per the label, label every bottle, and match the right cleaner to each surface — clean before you disinfect, and keep it wet for the contact time.

• Applies to: All cleaners who mix or use cleaning chemicals.
• Frequency: Whenever products are diluted, decanted, or used.
• Scope: Covers the dilution, labeling, and surface-matching PROCESS. Chemical safety, PPE, ventilation, and SDS handling follow your safety plan and the product label.

What you need

• Measuring device or dilution system
• Secondary spray bottles + labels

The procedure, step by step

1. Dilute exactly per the product label — Use the dilution ratio and water temperature printed on the label — do not eyeball it. Over-concentrating wastes product, leaves residue, and can damage surfaces; under-concentrating fails to clean or disinfect.
2. Never mix products — Do not combine cleaning chemicals. (Mixing hazards are a safety matter — follow your safety plan and the product labels.)
3. Label every secondary bottle — Any bottle a product is transferred into must be labeled with the product name and its basic hazard info, so cleaners always use the right chemical and never confuse two. A shared crew spray bottle is not exempt — label it.
4. Match the cleaner to the surface — Use the right product for each surface — all-purpose, glass, bathroom, degreaser, or sanitizer — and follow the label’s “directions for use” for which surfaces it is approved on.
5. Clean before you disinfect or sanitize — Disinfectant does not work on a dirty surface. Clean off soil first, then apply the disinfectant/sanitizer and keep the surface visibly wet for the full contact time on its label; reapply if it dries early.

Quality check before you finish

• Products diluted to the label ratio (and water temp).
• No products mixed.
• Every secondary bottle labeled (name + basic hazard).
• Correct product used for each surface per its label.
• Surfaces cleaned before disinfecting; kept wet for contact time.

This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a House Cleaning business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan.
