Cotton rags and mixed rags were compared to Tork Heavy- Duty Cleaning Cloths. Panel test conducted by Swerea Research Institute, Sweden, 2014.
**Test two: Removing 10 g of a mix of asphalt 2/3 and grease 1/3 that had dried for 1 hour, from a metal surface 60 x 90 cm with the aid of a degreaser, CRC brake degreaser. After the task, panel participants were asked to evaluate the energy needed on a 1–4 scale with perceived energy being; 1) very easy, 2) easy, 3) tough, 4) very tough. Cotton rags and mixed rags were compared to Tork Heavy Duty Cleaning Cloths and Tork Industrial Heavy-Duty Cleaning Cloths. Panel test conducted by Swerea Research Institute, Sweden, 2014.
