Acetone would not work for a soak off gel as it would start to break it down and undermine the service ... Stick to 99% I P alcohol which is actually much more expensive from a chemist than D.Sperse from Sweet Squared 08452106960, which you can get in professional-sized quantities for your Business. It smells very nice and fresh and professional plus it does the job perfectly and will work with any system. I use it for both soak off and hard gels. HTH
