99p for a 300ml tin. Far cheaper than branded alternatives.
I've been using this stuff, which is their engine degreaser, on my drivetrain and it's been excellent: http://www.lidl.co.uk/uk/home.nsf/pages/c.o.20090310.p.Engine_Cleaner.ar11
The top one is chain specific though. The nozzle on the cans is actually very good as it's a jet rather than a spray which makes it far easier to direct it exactly where you want it, with less wastage.
Thanks for heads up, I'll get some stock in!
they've also got silicon spray, bit of lube for your forks/shock
(or some ppl spray it on everything [frame etc] to help mud sticking)
I've got some of their disc-brake cleaner degreaser.
Big sign on the back about how it will melt icecaps, kill polar bears by the dozen and poison all the local reservoirs.
Dunt half get the filth off though ๐
