Nah, can't see it myself, particularly in the UK. If a Water Pressure washer at 90psi can't remove grime then I can't see this working. They might use a cleaner solution that is quite harsh, so paintwork would ultimately suffer. That is unless in 2020 paint isn't used and there is an alternative.

In 2020 i'll not have the energy to clean my car so I hope it works.
