On the suppliers website (listawood) it says travel mugs and water bottles 190c for 40 seconds.
Yet other sites say 170-180c for 180 seconds.
which is it going to be?
i think 40 seconds is a little too quick but they are aluminium so maybe 40 seconds is right??
I don’t know what to think.
does anyone else use travel mugs and water bottles?
TIA
