Zep ZU50532 Fast 505 Cleaner and Degreaser 32 Ounces, 32 Fl Oz, clear

Don't waste money on Tecnu, it isn't even that good, what you need to do is chemically and mechanically remove the oil. Whatever you would normally use to remove oil or grease from skin or plastic is going to work the best. Personally, I keep ZEP Cherry Bomb in the shower and use it on my forearms and lower legs after rounds with suspected contact. $9 for 48oz. and it has pumice in it to help mechanically remove the urushiol:https://www.amazon.com/ZEP-ZUCBHC48-48OZ-Cherry-Cleaner/dp/B01MSL3XM4/ref=sr_1_4 For discs, ZEP makes a plastic safe degreaser as well, Fast 505 comes in a spray bottle for $5, grab some terry cloth rags as well (again, mechanically remove the oil) and then toss them in the washing machine:https://www.amazon.com/ZEP-Cleaner-Degreaser-Ounce-ZU50532/dp/B001BYDGIW Note: dish soap also does a nearly-as-good job as above and is even cheaper. Tecnu is $14 for 12 oz. don't waste your money
