Fuel Can Difference

So do I and i use them for diesel As long as they are fairly dry they will be OK

With plastic about the only difference can be the colour.

Generally they need to be better quality to carry petrol, which is a stronger solvent and then diesel & water in descending order. So if they're suitable to carry petrol, they are also suitable for diesel & water, as long as they are clean. Similarly, diesel rated jerries are not suitable for petrol but they are ok for water but water rated jerries are absolutely not suitable for diesel or petrol.

Once they've had petrol in them they would be contaminated for the purposes of carrying water - there may be something you can clean them with but I'm not sure I'd trust it, having had to live on water that smelt like petrol once or twice!

But I've interchanged petrol & diesel pretty easily just by making sure you rinse a jerry out that's had diesel in it with some petrol and leaving to to air for a while.

Hope this is clear enough.

Never store Diesel in containers or fittings made of Zinc.

Galvanised containers are great for drinking water, very bad for Diesel.
