What does a 1:10 dilution ratio mean?

A 1:10 ratio means 1 part concentrate to 10 parts water. So for 1 litre of solution, you need approximately 91 ml of concentrate and 909 ml of water. The total parts are 1 + 10 = 11.

Why is correct dilution important?

Too concentrated wastes product, may damage surfaces, and can be a health risk. Too dilute means the product will not clean effectively. Following manufacturer dilution rates ensures the product works as intended and is cost-effective.

How do I measure small amounts of concentrate?

Use a measuring jug or calibrated dosing pump. Many commercial suppliers sell dosing caps or wall-mounted dilution systems. For very small amounts, a syringe is accurate. Never guess — even small variations significantly affect cleaning performance.

Should I add concentrate to water or water to concentrate?

Always add concentrate to water, not the other way around. This reduces splashing of undiluted chemical and ensures even mixing. Fill the container with most of the water first, then add the concentrate, then top up.

How We Calculate This

For a dilution ratio of 1:N (1 part concentrate to N parts water):

Total parts = 1 + N
Concentrate = Total solution / Total parts
Water = Total solution - Concentrate
Containers = Total solution / Container size (rounded up)
Cost per litre = Concentrate cost per litre / Total parts

The waste allowance accounts for spillage and residue left in containers.
