hello all. quiet day again here....managed to solve one of those stupid problems. I had some bottles of car engine stuff in the garage, years old. Apart from knowing that one was antifreeze, i had no idea what was in the others and as the bottles were old and possibly fragile, I didn't fancy putting them in my car to take to the tip, even assuming that the tip would have accepted them. Anyway I finally found a local hazardous waste collection firm who deal with individuals and not just big firms and would collect and dispose of pretty much anything properly so they came today and collected the stuff. It cost a bit but its a real weight off my mind.
