Due to the smell of Paragon our carpet track only uses SXT 3.0 and have plenty of grip letting it soak for 10-15 mins. I usually clean the tires with a solvent between rounds but did try full strength Simple Green and by the end of the day the tires were too soft and sticky to the touch ( they also had and extra long soaking of SXT for 45 mins). So only use the Green to clean when you need extra grip. Diluted Simple Green 50/50 with water may work better but for now back to my trusted solvent cleaning.
