Great video. I have been unable to clean the inside of the tank on my Kawasaki to my satisfaction and will give this a go. One observation I made: The green pad you used on the exterior has a tendency to scratch plastic. I suggest trying the blue Scotch-Brite non-scratch sponges (that may be found at the grocer's, alongside dishwashing products). I think the blue pads are made from a recycled plastic material, so they don't tend to scratch softer materials while still being very effective.
Good result. Putting in some small gravel (aquarium gravel or equivalent) and giving it a good shake can help loosen up the stubborn debris BUT only on single-skin coolant expansion tanks. Some coolant tanks (such as on Peugeot 206 etc) have a double wall and cleaning them and getting the stones out afterwards is somewhat challenging.
I would avoid the harsh chemicals, sometimes these will compromise the integrity of the plastic and decrease the life span of the tank leading to cracks and leaks.
