cleaning rusty components using vinegarr http://www.cookhaus.co.uk/vinegar/index.htm not sure what i could use it on myself, but ill give it a shot one day
And descaling kettle filters and kettles, showerheads, good for azaleas, bee stings, dog/cat pee, use white vinegar, it neutralises the smell, salt and vinegar paste for stained cups/mugs, removing price stickers. Very underestimated.
a guy i know, dan is currently rebuilding his punto gt and used vinegar on alot of the parts, in a massive plastic box with lots of cheap bottles, worked a treat! stinky as though.
I love the tesco's stuff, have used it on bumper bolts/brackets etc Ive got about twenty five bottles left yet but will always come in handy!
