Try like hell to hand wash. If that doesn't work Plan B is to wash with pressure wand/brush at commercial self-wash place. Plan C is modern brush type car wash (I have many to choose from & most are very newly built). Plan D would normally be to keep it dirty until A/B or C could be done. I basically don't use touchless after bad experience with one years ago (& seeing coworkers/friends have varrying luck with them as well).
