Hi DK nice to hear from you as always good common sense, We bought our first JR from you and the second one. Regarding engine washes, the whole of the UK is considered a salt laden environment, but it is not always possible to carry out washes, not as per the book anyway, but I advised private owners to carry out the wash prior to flying saving engine starts, not as efficient as after flying but better than nothing, also try and do one once a week, As one of my old colleagues once said books are for the guidance of wise men and the obedience of idiots, and we all have the choice , happy flying
