For a slightly deeper clean, use a mild household detergent along with a shop cloth. [3] X Research source
Use a water-soluble marker so the marks can easily be wiped away with a damp cloth when you are finished. [5] X Research source If making straight cuts, use a ruler or straight-edge to guide the marks. For curved lines or circles, use a compass or protractor. You can also trace curved objects, like bowls or coffee cans to stay precise.
Use a flat board and clamp each end to the table to hold the entire sheet of plastic flat and to provide yourself with a straight-edge. [6] X Research source
Use a thicker blade so the plastic does not melt and stick back together. [8] X Research source Other alternatives include cutter tools or a grinder with a metal cutting blade.
Drill holes to use as starting points for the blade and shave away the plastic until you reach the guide lines. [10] X Research source
Drill holes in the plastic along the guide lines so your blade has places to start and stop easily. [13] X Research source Make straight relief cuts from the outside of the plastic to the curves. This will help prevent the plastic from warping and shortens the cutting distance. Leave room between the guide lines you’ve drawn and where you cut. You can always file these down later.
Use your thumb to guide the blade when you make the initial cut. From there, place the saw into the line you’ve made and pull the saw through. [15] X Research source
Use long, steady strokes to avoid heating and melting the plastic. [17] X Research source
