Blue Frog you have a picture of the bottle of this stuff with non-caustic written on it,YET BOSHRAVIE SAYS IT IS CAUSTIC.
You now seem to be actively promoting it.
You just cannot have a product on sale labelled non-caustic and then tell people it is caustic.Its amateur,its pathetic,its misleading,its therefore also potentially dangerous.From memory i think the larger size or the ebay ad states non-acidic!
I can not remember the last time i found myself so annoyed by content on this forum.
Generally you can expect good advice on here but to see this incorrectly labelled, hazardous liquid, being promoted with seemingly zero credentials of safety other than a home made misleading label just beggars belief.
