PURE, clean, crisp and clear: after the dirtiest spread in camera club so far last week (ooh Matron), hopefully this week’s collection is a soothing and calming palate cleanser.

The title – Clean as a Whistle – meant to imply straight lines, clutterless surfaces and bold colours.

We got some of that, but, as ever, we also got a few more witty interpretations of the brief.

Ian Marriott took the opportunity to bring his other life as a coach at Oxford City Athletic Club into play for this perfect shot of one of his athletes vaulting backwards very cleanly (from the looks of it) over the bar (thanks to Sports Desk for revealing that she is actually performing a Fosbury Flop).

A lot of you chose a subject which might not immediately bring the word 'clean' to mind: engines.

Lesley Adams and Peter Greenway both shared shots of very shiny vehicle engines up close, while Donna Cassettari chose a gleaming steam engine and Simon Jaggs some tidy-looking trams at Crich Tramway Village in Matlock.

Many more of you took the theme as literally as possible.

Ann Faulkner captured a perfect portrait of her granddaughter Kairi in a bath full of bubbles while Emilia Zipis shared a surprisingly satisfying picture of the inside of her washing machine.

A shower head would not strike many of us as an obvious subject for arty photography but Gordon Craig found the beauty in water droplets hanging on his like frozen icicles.

John Parsons, meanwhile, made us smile with this pup pawtrait of a hygienic hound washing his paws in a fountain.

Andy Proper and Becca Collacott found naturally crisp subject matter in this snow-white moggy and swan respectively.

Thanks to Christian Barrett for the obligatory clean whistle.

For next week's theme, we're going to swing the pendulum fully back the other way: The Ugliest Place I Know.

Try to avoid being personal – we're not going to run pictures of your neighbour's garden gnome display (at least not without their written consent) – and please tell us what we are looking at!
