1 cup (250ml) vinegar
1 quart (1 liter) warm water
2 to 3 drops dishwashing liquid
Need to take down some wallpaper? Before you rush out to rent a cumbersome steam machine or buy an expensive paper-removing product, whip up a batch of this vinegar formula for a mere fraction of the cost: in a large bucket or bowl, combine the vinegar and warm water and add a few drops of dishwashing detergent to the mix (feel free to make a larger batch if necessary). Use a sponge to apply the solution liberally to the old paper. Let stand for 5 to 10 minutes and then scrape off the paper with a putty knife. To remove all traces of glue, use a nylon sponge to give the walls a final wash with the same solution.
