Thanks for that. Next time I will use washing up liquid. I assume you use quite hot water to remove any wax/sealants. Do most tar removal products remove sealant/wax? White spirit at £1 for 500ml is certainly a lot better value than specific tar removers!using white spirit means that those parts not wont have sealant/wax. The simplest way to remove wax and most sealants is using washing up liquid and washing it with that.
