although I like the above fresh ideas there are alternative ways of taking wall papers out,
when i was repairing my house i thpught I'd get a steamer cause it is cheap and efficient but it turned out to be realy time consuming and it didnt work everywhere, Instead you can use scorer to make tiny slots throughout the paper and then use glue dissolvant to help you take the papers out in huge chunks, easy and quick ckeck this out -
