WD-40 44709 Specialist Fast Release Penetrant 250ml

I fought with a rusted screw in a wiper for a few days with the tools and regular WD40. This helped to remove the broken wiper and the stuck screw.

My main reason for the purchase was to use on sticky/frozen locks and padlocks but haven't been able to test it yet.So far I've only used it to free seized UPVC window locks. Compared to standard WD40 it works faster and needs fewer sprays.

Good

Bought on the strength of the description. Fluid works very well (on tight car door hinge) but has a stupid plastic addition supposed to 'direct' the spray in a jet...accurately! I tore mine off because the spray went everywhere. Now it's a bit full on but seems to be OK for my use. A £7 can used every day for a week versus a visit to a Ford bodyshop!! Bargain.....it worked.

Used for removing brake discs on a Ford focus (known for rust and corrosion)I give it ten minutes after application and it did its thing freeing up discs that wouldn’t move even with a club hammer previously. Definitely good stuff from a trusted brand.

I used it to make a glow plug easy to remove and it worked, just sprayed it over a week and out it came with no problems

we all know what wd40 is quality so nothing needs said

Does what it says on the tin
