I had pulled over to talk to my mom on the phone one day and noticed my steering wheel cover was filthy!! (my hubby is a mechanic so this makes sense LOL) I reached into my glove box and grabbed a napkin and grabbed my travel doTerra Lemon too! 2 dabs on the napkin, a couple seconds of scrubbing and voila! Clean! And it's still clean! Thank you doTerra for giving us the tools we need :)
