Concentrate vs. water in the batch
Measure the concentrate first, then top up with water to reach the total batch volume — not the other way round — so the final ratio stays accurate regardless of small measuring errors on the water side. Keep a dosing chart posted near the mixing station for the batch sizes your team uses most.
Frequently asked questions
What does a dosage of mL per litre mean?
A dosage of 20ml/L means adding 20ml of concentrate for every litre of final solution, with the rest made up of water.
How do I calculate concentrate needed for a batch?
Multiply the dosage rate by the batch volume. 20ml/L for a 10 litre batch needs 200ml of concentrate, topped up with water to 10 litres.
Why does over-dosing waste more than just product?
It increases cost per batch directly, but can also cause residue, surface damage, or slower rinse times that add labour cost too.
