Abstract: Systems and methods are provided for removing a stain from a surface. A first solution is applied to the stain, wherein the first solution comprises a combination of an ammoniated substance such as ammonium hydroxide and an alcohol such as isopropanol. A second solution is then applied to the stain treated with the first solution, wherein the second solution comprises between approximately 6% and approximately 15% hydrogen peroxide.

Abstract: A tool and method of using that tool in construction to assist in fixing pipes during construction. The method includes: a) providing a magnetically susceptible strut having a channel with a frontal opening formed by three walls forming three sides of the channel; b) inserting the first arm of the tool of claim one inside the channel, with the magnet attaching the first arm to a wall of the channel adjacent the frontal opening, so that the second arm forms an angle of 90° or less with an end designated as an upper end of the strut; c) placing a pipe within the angle of 90° or less and supporting the pipe solely by temporary forces securing the tool within the channel; d) securing the pipe to the strut; and e) removing the tool from the channel.
