Lets play a game.
I'll set the scene first:
Lets say that your wife... we'll call here Mrs Steve for now... is currently away with "the girls" and will be back home on sunday evening at approximately 6pm.
Lets also say that your wife, after much debate and incredibly dull conversation, has finally choosen a carpet that she likes. And it's bright white. Your wife friggin' LOVES this carpet
Now lets say that you... we'll call you Steve for now... have decided to spend the evening sharpening chisels at the table in front of the TV, but, being unable to find any 3 in 1 oil, opted to use car Engine oil instead. To make this a bit more realistic for you, we'll pretend that you were using Castrol 10w/40 partially synthetic oil.
Now, finally, lets say you are a cack handed so and so and when the phone unexpected rang, you knocked the bottle of engine oil off the table and onto your pretend wife's brand new carpet.
So here's the game:
If such a circumstance had happened, how would one get the oil out of the carpet in such a way that when your wife returned home at 6pm on sunday she wouldn't know?
Obviously this HASN'T actually happened. And why would it? No one would be stupid enough to knock a bottle of engine oil over there wife's new carpet.
But, if we assume that some one WAS that dense, and now they had approximately 44 hours to remove the oil, what would they do?
For reference - and purely becuase it makes the game more fun - you can assume that the person who knocked the oil onto the carpet has already mopped up the worst of it, and also spent a while scrubbing at the stain with a petrol covered cloth to little effect...
We can also assume that this pretend person called Steve has begged 5 liters of DMSO from a chap he knows at a local chemsitry department, but there is no certainty that it would get to you before sunday evening, and so that option - which will definately work - is out of the window.
