Looking at the interesting link you posted, Dove, I'm at a loss to know why putting quantities of sodium chloride or acetic acid (salt & vinegar to you and me) on my garden to kill weeds, should be considered eco-friendly...
Some people are bamboozled by the word "natural".
Since 2019 I've lived in east Clare, in the west of Ireland.
I am aware of some of the history even if not involved in it personally as I've been reading this forum for a few years, but nevertheless, I think kindness is important. If you can't bring yourself to do that, ignoring a person is better than ridicule. I know I've annoyed people on here and people have annoyed me but for the most part we all bump along. It's hard to know what else is happening in someone's life and how important this forum may be to them.
I would think the path and patio stays in the soil preventing weed germination while the other stuff is inactive once it hits the soil. If you read the labels, always a good idea, it will tell you.
As I said, the labels are exactly the same, except for a "search & replace" done to the product name.
They only claim to contain the same chemical in the same proportions and both say they're biodegradable. I've searched the Web and looked at the Doff website, but I cannot find a single reference to any differences between these products.
Also, does anyone know if weed killer goes off? I just used the last of the old bottle, which has pretty much stood with only a little bit left in it since last year, and it doesn't seem to have worked as well as I expected. I'm yet to start the new bottle (it's raining today) but I'm sure it'll work quicker and more effectively.
The red bottled 'Patio Weedkiller' is purported to conatin 7.2g per litre of glyphosate on some sites. But on the safety data sheets, it seems to only contain 31.02g/l. Perlagonic acid - which is basically for killing algae, moss and liverworts i.e. cleaning patios of stuff that gyphosate will barely touch.
The yellow bottle stuff is 7.2g/ l of glyphosate alone for weeds.
Seems the product packaging, details and data make it somewhat hard to tell what's going on the Doff camp.
I remember there was an article in "Gardening Which" complaining that chemicals manufacturers were selling exactly the same bug killer labelled differently, to encourage you to buy 2 bottles, one for your roses, say, and one for your houseplants. I guess the same is likely to be true for weedkillers, especially now the range of chemicals available to amateur gardeners has shrunk so much.
Maybe Doff just wants you to buy two bottles when you could have managed with just one...

Yes, that's always puzzled me Liri. I usually get shot down when I say they're just more chemicals.

Agree .... vinegar = acetic acid.
Do people really want to go around drenching their gardens and defenceless (and useful) invertebrates in acid?
I think it would have been interesting if the first section in that link was split into Selective and Non-selective

It's a hard one getting to the bottom of this one. Presumably you're using the trigger spray/ ready to use bottles.
Here's a site that lists both products https://www.lsengineers.co.uk/catalogsearch/result/?q=doff+rtu&x=0&y=0
