Pcolbeck.. who uses five litres of WD40? I have several cans bougth over the years, and I am sure they will form part of my legacy.
It is the one thing lurking at the back of shelves in any garage, that and 3 in 1 oil.
ps. Dont get me started on trigger packs, ie those bottles with the spray attachment. I completely agree with using one for WD40.
It is a CRYING SHAME that such finely engineered pieces of equipment, made using the worls oil supply, are used once then binned.
I saw in a supermarked once a concentrated little tube of kitchen cleaning fluid. Drop into a used trigger pack, fill with water, and voila. Such a good idea. But I never saw them much again. That idea both saved plastic and the stupidity of moving water by the lorryload across the country.
