to quote a song,

"It's possible to do things alone,

Slash tires, glue up locks

Butchers, burger bars, the furriers,

Smash windows, bankrupt the lot

Throw paint over shops and houses

Paint stripper works great on cars

Chewing gum sticks well to fur coats

A seized engine just won't start

Sand in the petrol tank means that delivery's going nowhere"

I imagine sand would be harder to remove than water
