Safe solutions for an over-tight chainring removal?

I am trying to remove my Campy 10 sp cassette. With an effort that caused the breaking of the large adjustable pliers (I don't have a hexagonal wrench on hand) I am wondering what may safely aid me in getting it off. Can I use, say, Liquid wrench?

Any other solutions or should I just keep putting in the effort that reminds me of trying to remove a seized seatpost

Cassette (rear) or chainring (front) or crankset (all of the front bits -cranks and chainrings).
Without the correct tools you could damage the parts.
parktools.com has a good illustrated guide but you have to know which part of ther bike you want to remove.

Sorry, I meant rear cassette chainring lock

I do use the park tools instruction. However my problem is that it is way too tight and I am worried about the damages to the wheel with the amount of effort that it seems is required to remove this.

You need a lockring removal tool and a chainwhip to remove a cassette. Clamp the tool in place with the qr skewer and be sure you are turning the removal tool the correct way, it has standard right-hand threads. Wrap the chain whip around one of the cogs and hold the cassette stationary while you thurn the removal tool. You can turn the wheel over and clamp the remover tool in a bench vise instead of using a wrench if you have one available.

All done. Yes the proper wrench was what was needed. Thanks all.
