I'm not convinced about the cost. A kilogram of borax seems to run about $10CAD. 2 cups, at 1.7g/CC, would be about 850g, so $7 just for the Borax. Unless there's a much cheaper place to get it...

A ~5L jug of Tide costs $31, or about $6/L. If they have approximately equivalent cleaning power per volume, Tide wins.

Most of that tide jug is water.

Yeah, which is why I added the note about cleaning power per unit volume. But it'd have to be a fair bit more powerful to make the effort worth it, I think.

We use maybe 50ml of Tide (so that'd be probably 100 loads) when doing our laundry, so if that's equivalent to like one tablespoon of the Borax mix, I could see it saving me $20 or so overall, if it's three times stronger.

So it'd come down to how much time I spend shopping and combining the mixture vs just buying it.

Mind, that's just the borax. Bar soap and baking soda are cheap but not free.

(edit: and before someone jumps on me about "baking soda", I was thinking of it in terms of decomposing it into carbonate in the oven. I haven't priced out washing soda)
