Mitsubishi Lancer - How to clean lash adjusters/tappets

Hope this is of help to someone, a cure for lash adjuster 'rattle'. Thanks to Evo 400 and Mark Shead for advice and to Shaunevo for doing it (with a little help from me)
And before somebody says why bother
i. The noise is bloody annoying
ii. It will eventually cause camshaft wear
