WD40 has stained a cedar door

soph001, Mar 12, 1:58pm
This is the first time this has ever happened to me.

I got some overspray on the door (wiped at it immediately after) and the customer rings back 3 weeks later saying it has stained the door.

The wood is cedar and it has has some sort of finish.It's a much darker brown than natural. And a hard-type of finish, not just oiled or whatever.

Any Tips! Apart from sanding the whole friggin door!

(Doesn't help that it's for a friend of a friend of someone we regularly do work for)

It's fish oil - therefore a fine penetrating oil. Absolutely magic stuff with unbelievable applications for just about everything. I have no quick fix, other than to suggest you go over the whole door with it so the stain melds with the total surface and disappears.

Try puffing talcom powder on it,leave it for a while and brush it off.

wd40 = oil + solvent.

I believe, if the oil stained the door, reply #2 and 3 may work.

but.if the solvent damaged the protective finished coat you may need to strip and redo.I know it sucks lol.

btw it does not smell like fish !
being fish oil is a fallacy.

Hmmm. I was hoping for an "anti WD40" type product :) LOL
This is why I HATE doing favours for people who know someone who knows someone.

Isn't wd40 something like a crc!
If it is I don't expect it will be an easy fix.
Unless you say all care no responsibility then just redo it and move on.

Try evaporating white spirits (lighter fuel) on it.

Can you ring the WD40 people and ask them!Might be a number on the can.

I thought that WD40/CRC etc are a diesel base so maybe an engine degreaser spray and a wash off with the hose.

Problem I can see is that the cure may be worse than the problem unless you get exactly the right product.

Sounds like an insurance job !

Wd 40 is a fish oil, hydrocarbon blend. If you treat the area effected only it will show up as a "patch", what ever you do. . Best option is to strip whole door and start from clean again. Possibly stain the stripped door with oil based stain, like Thompsonsor similar product. Guessing as you state door has been finished , it still has the cedar look not the grey / white / silver, weathered look
