The correct way to lubricate a lock

Extracted and edited from an article by David Snell in the Daily Telegraph Property Clinic March 31st 2007.

A reader writes:
I am frequently told that locks should be lubricated by means of a graphite puffer. The DIY stores which have replaced good old ironmongers look at me as though I am on a different planet when I ask for one and suggest WD40. Where are these puffers available?

David Snell writes:
I am sure that WD40 will do the trick as far as the working of the lock is concerned but pumping the keyhole full of oil could be injurious to your door finish; the oil may even run out on to your carpets. The Graphite Trading Company (www.graphite trading.co.uk) does indeed have a graphite puffer called an Edelgraphit, priced at £5.25 plus VAT and delivery.

The blurb says that, if used regularly, it keeps all locks lubricated and working smoothly. It also guards against sticking and dirt build up, prevents lock-outs, wear and corrosion. It is greaseless, odourless and weatherproof and each puffer contains 45 grams of superfine, natural, graphite powder. I simply cannot understand why they are not more universally available or promoted.

Webmaster comment:
I can remember my days back in the 1970's working in an ironmongers' selling a lot of these puffers and cannot understand why they are not more universally available or promoted nowadays.

Buying advice: Graphite powder is available in the Fitting Essentials section of this website listed under Lubricants and Greases and for the Garage Door Trade from www.sparesmaster.co.uk  - in each case at a lower price than the Edelgraphit product above.
