All 62 SKUs, with the litres in the pack and the price per litre of concentrate. Below that, what the step from 5 L to 25 L is worth per litre, and, for every grade with a published dilution, the cost per litre of the solution you actually use. Every figure on this page is a division you can repeat.
Prices in Canadian dollars. Price per litre is the pack price divided by the litres in the pack: a sale price where one is set, the list price otherwise. Kits are not sold by volume, so they carry no per-litre figure.Download the whole table as CSV →
5 L to 25 L, per litre
The same grade, five times the volume. This is the difference in price per litre, and the share of the smaller pack's per-litre price it takes off.
A saving per litre is not a saving until the drum is used. A 25 L pack is five times the commitment and needs somewhere frost-free to sit.Bulk and pallet orders →
Cost per litre of ready-to-use solution
Concentrate is not what you use; the diluted solution is. Where Lactaz publishes a ratio, the price per litre of concentrate is divided by the number of parts that ratio makes. That is all this is: a division. It is not a claim that one grade goes further than another, and it says nothing about how well anything cleans.
price per litre of concentrate ÷ (ratio + 1 part concentrate) = price per litre of solution
The arithmetic, in full.
A ratio published as a range produces a range of costs, shown as a band. The looser end of the range makes more solution and costs less per litre; the tighter end costs more. Neither end is presented alone.
Dilute 1:6 (increase concentration for tougher dirt).

These grades have no published dilution ratio, so there is no cost per litre of solution to compute. Nothing is estimated from a sibling grade, and no ratio is read out of a set of volumes.
Kits, bundles and the skin-care range are sold ready to use and are not diluted at all.
Dilution ratios as published by Lactaz in its own product copy. Confirm the correct ratio for your system against the current safety data sheet before first use.
Why the 500 mL industrial packs sell out
9 of the 9 industrial 500 mL SKUs are out of stock right now. A 500 mL bottle is the cheapest way into a grade: the lowest price on the shelf, and the smallest commitment before a 5 L or a 25 L pack.
The sample kit is the deliberate way in: Eco-Cleaning Sample Kit, from $10.00. It is not free, on purpose.
