DMR V6 pedal axles really stiff; solutions?

I bought a set of these ages ago, meant to post here to ask a question, then forgot all about it. Found them the other day whilst having a clear out. The problem is that the axles are really stiff and don't turn freely. If I put them on a bike, they don't spin to allow easy foot placement, so are quite dangerous. Seems the stiffness is due to the plastic bushings used; perhaps this will free up through use, but I'm loathe to try to find out as I don't want to risk it out on busy roads. I would return them but I bought them from a shop up north and don't have a receipt anyway. And they were £17.99 so it's not worth the hassle. Is there any way I can get them to spin properly, or should I just throw them in the bin?

They'll loosen off with a bit of use

Unless they're so stiff you can't turn them by hand, you might be over thinking it.

I have had this with pedals with bushings.  I stripped them and cleaned out the very thick grease in them and replaced with a normal grease IIRC - they span fine afterwards.  I assume its for longevity

I have found new pedals to be very stiff a few times - some with bearings were overtight so again a strip and reasemble with the bearings properly set up and they were fine

They're stiff enough that turning the axles by hand is hard work.On a bike they do not spin at all, and whilst they go round, they stay in one position so it's hard to place your foot on them. Dangerous especially in traffic etc. I don't want to use them until they spin freely. How long will that take anyway? Tried spraying a bit of WD40 in them, after prising off the dust cap. That hasn't helped at all. I'm assuming the bushings are cheap affairs that are made to be tight when new, and just wear loose. I expect these pedals are of very poor quality, and a mistake purchase. I might find someone with an exercise bike, they'll probably be ok there. Or I was thinking of using a power drill to put some serious revs through them, in an attempt to loosen them up. I'm going to buy some other cheap plastic pedals anyway, ones that actually work properly. These are rubbish. I've got other DMR pedals, ones with proper bearings, they've been great.

Worth an email to DMR asking for advice?

WD40 is not a lubricant.  Don't do that.

The stiff pedals I had that didn't work either.  I had to strip them to remove the super thick grease.  Downside being that they will need relubing sooner.  Its not difficult to do so.

Get shot of them and buy some pedals where the pins aren’t slippery as ice and don’t all snap off on the first ride

Have a couple of pairs of these and they will loosen up eventually but we only have them on bikes for 'gentle terrain'. 

Can you pop them in a vice and spin them up with a drill to bed them in?
