Result of using WD40 as a finish on veneer?
Hello All,
Today I picked up a radiogram, early to mid- 40s at first look, not yet sure of maker as the dial is a bit sad. However, I find the gentleman I purchased it from has "restored" it for sale by liberally spraying WD40 on the gram mechanicals to free them up, the pots of the radio as far as he could get it in to reduce crackling AND, not content with this, he has doused the entire veneer surface with it. Now the surface has a "patina" but considering its age it is not too bad, certainly it only needs major repair work in a few areas. However, I am wondering what the long-term impact of the WD40 will be - could it cause the veneer to lift? (as far as I know it was sprayed only a couple of weeks ago and it looks ok so far -- well I think it looks ok, I need to get it into the sunlight tomorrow for a clear look -- although it is clearly still fairly moist). So, my question is what do members think the impact of the WD40 will be on the veneer, and given this "base coat" how should I best proceed with "feeding" and polishing the veneer. (I am not actually sure what the current top coat finish is as it is rather masked by the WD40 - at the moment its sort of dullish with an overlay of oil from the WD40......) (Mods, I've posted in this part of the forum rather than the audio section, as it is really a generic question re cabinet finishing.....please move me over if I'm incorrectly located) regards Bruce |

As far as the veneer goes, it depends on the finish. I'd be more concerned about the deck mechanicals - WD40 will have washed all the lubricant off everywhere, so a complete strip clean is required; you might have to start a new thread if you want to proceed.

Re: Result of using WD40 as a finish on veneer?
I don't think this will be a disaster. WD40 is basically a mixture of white spirit (a bit like kerosene, often used as a paint thinner or cleaner and ages ago used in dry cleaning) and light machine oil. I would leave it for a while so that the white spirit can evaporate (you will know this is complete when it stops stinking of WD40). Then treat it with Danish oil or a similar finish depending on your preference.
I'm not as WD40-phobic as many people on the forum. I've found it works very well on carbon tracks in pots, much better than standard contact cleaner. It's certainly not a good idea to spray it everywhere though. Paul |

Re: Result of using WD40 as a finish on veneer?
I was taught a trick - apply very hot linseed oil and work hard to remove haze and minor cracking to cellulose finish.
I've also been playing around with Danish oil to repair lost finish around knobs etc. and it seems to adhere to cellulose OK. |

Re: Result of using WD40 as a finish on veneer?
I Agree with Paul. WD40 has it's uses! And that smell does take me back to my childhood...
Don't spray it everywhere, but where Servisol fails, or in really bad cases, WD40 is useful. Just keep it away from Rubber parts and sensetive mechanisms. And flames... The pots will be OK, the veneer - leave and see - but the record deck is a different matter. It is good for cleaning stuff I admit. Cheers, Steve P.

Re: Result of using WD40 as a finish on veneer?
I recently collected a radio from a helpfully-minded individual who decided to give it a clean before handing it over. They had obviously reached for an aerosol to give it a quick squirt of polish, but picked the wrong can. My radio now reeks of 'Raid' Fly & Wasp Killer!!
Luckily, it seems to have done no harm to the lacquer finish. |

Re: Result of using WD40 as a finish on veneer?
Danish Oil is excellent stuff - I often put it on with a brush, leave for a week or so and use 000 steel wool to give a matt finish, followed by more Danish Oil, but using a cloth. The finish is almost as good as French polish, sometimes.

The problem with the stuff is many folk regard it as a lubricant, which it is not intended to be. If you are using ammoniated clock cleaner on a record or tape deck and any brass parts end up bright green, you know who the suspect is!

Re: Result of using WD40 as a finish on veneer?
Regarding cabinets and a bit OT, I was speaking to my local furniture restorer friend and he told me that when he was an apprentice his boss demonstrated the removal of white rings caused by water on french polished cabinets by dousing the top with meths and then igniting it. The meths flared up and the stain was gone. My cabinet maker friend surmises that the heat briefly melted the polish, releasing the trapped moisture under/in it. Can you imagine the reaction of a customer if you did that to his priceless Dynatron or whatever in his home! Needless to say my friend has never had the courage to try it himself.
I don't use WD40 for much in radio restoration but I guess it's horses for courses and whatever works for you at the end of the day. Ian. |

However all the pots and switches are fine and I have continued to use WD40. The three Leak Strereo 30 that I serviced recently had all their slide switches and pots sprayed with WD40 and are fine. |

Re: Result of using WD40 as a finish on veneer?
WD40 cleans contacts very well, but the problems are caused by the mineral oil layer left behind once the white spirit has evaporated. This is a positive thing inside a pot but elsewhere will attract dust and other undesirable stuff. It was originally designed as an anticorrosive spray to protect Atlas missiles and the oily residue is intentional.

Re: Result of using WD40 as a finish on veneer?
Thanks to all who have replied here - I am relieved to find that most think the WD40 will have no long-term impact on the veneer. I think the wait and see approach is good advice. The veneer is clearly still very moist and I'll give it some time to dry out before applying danish oil -- I'm looking forward to replacing the smell of WD40 with danish.
I'm not too worried about the impact of the WD40 on the radio/gram sections -- a closer inspection suggests the PO hasn't managed to get it in too deeply and its mainly been spot application on the radio pots and the gram bearings. So its mainly a fair bit of perished wiring and some caps to be replaced in the radio and a total strip and relub of the gram (the bearing, sounds awful at the moment) - that'll be interesting as I've not worked on a gram of this vintage. As soon as I get time I'll post some photos in the appropriate section as I'd like assistance in getting an approximate dating - with a steel needle and no speed other than 78 the unit is clearly older than I had initially thought.

Hi Bruce
The WD40 will do no harm, I have just restored a Victorian Vienna Pendulum clock, and gave the mechanism a spray of WD40, it now has a healthy tick tock, now keeps excellent time and will be resistant to damp and corrosion. Geof |

I have no real interest in clocks, but just want to avoid doing anthing detrimental to mechanisms in general.

Re: Result of using WD40 as a finish on veneer?
That is really getting OT now, which was my reason for post 14 (in which Geof and I have an on-going and useful discussion) - anyone is welcome to PM me on the subject.
Let's get back to Bruce's cabinet, please!

Re: Result of using WD40 as a finish on veneer?
I,ve just restored the cabinet on my Bush VHF62,as i do a lot of work restoring and re finishing rifle stocks i decided to try some birchwood casey "true oil" that i use on my stocks,after two coats the finish has realy brought out the grain and left a hard wearing surface to which i applied lord sheratons beeswax balm,it only took about a couple of days and the finish mirrirs the original.
