- § 03Which dilution ratio have I mixed if I added, say, 200 ml concentrate to 9.8 L water?Dilution ratio (reverse) →
- § 04How many hours (and per person, per week) does it take to clean a given area at my performance rate?Area / time consumption →
- § 05How many inspection units should I divide an area into for a DS/INSTA 800 quality inspection?INSTA 800 inspection units →
- § 06What is a medium with a given pH used for, and when is it too aggressive for the surface?pH guide →
- § 07How much concentrate and water gives e.g. 0.1% chlorine or 75% alcohol — and is the target within the recommended range?Disinfection — working solution →
- § 08How much water should a microfibre cloth absorb to be correctly damp — and how much water for the whole bunch?Microfibre — damp cloth →

New task? The guided wizard compiles the entire cleaning plan – inspection units, recommended frequency, time consumption and hours per week – based on your answers in three steps.
Dosing & dilution
Mix the chemicals correctly: dilution ratio → ml concentrate + water, conversion between ratio and percentage, and checking a mixture.
Time & planning
Plan the work: time required based on area and your own output rate (m²/hour) — per person and per week.
Quality control
Prepare a DS/INSTA 800 inspection: divide the area into inspection units of up to 100 m².
Chemistry & method
Choose the right agent and the right method: pH scale (acidic/neutral/basic), disinfection concentration and correct damp microfiber cloth.
Economy & consumption
Set price on the task: chemical cost per working solution and floor treatment per m² — calculated on your own prices and data sheet figures.
