the cleaner "Dissolving" refers to the melting of the ABS plastic Page 2 Test Notes & General Procedure The purpose of this test was to allow the markings to fully cure before attempting to clean them off. The first test specimen was a used aluminum plate, which was neither polished or rough. The test also included several discus plates of various materials: aluminum, bead-blasted aluminum, anodized aluminum, ABS plastic, fiberglass, painted fiberglass, carbon fiber, gel-coated fiberglass & wood. A grid of markings was made on the plate. The positions of the markings within each cell was consistent with regard to make and color. Groups of markings were made on all the discus plates, and numbered. The aluminum plate contained red & black markings, the discus plates contained mostly black markings, but some red was used, and a metallic silver Sharpie was used on the black plates. The test specimens were kept indoors during June due to the local weather conditions. They were left outdoors during July & August. The cleaning test was performed in early September. A reduced set of cleaners was used from the first cleaning test in 2009, eliminating the poor performers. All cleaning was performed with cotton balls. In some cases, the cleaner left a noticeable residue, virtually identical to the 2009 test. Therefore no comments about the residue were made in this report. The evaluation of the results (Excellent, Good, Fair, Poor) was somewhat subjective, but was made consistently by one person.
