I’ve used a couple of hand car washes but they never did a good job.
Then when speaking to an old school friend who was CID I found out that he has never known one not be involved in either people trafficking or money laundering
I use Morrisons once a week to wash underneath whatever car we were mainly using and just to get the grime off, only use the jetwash. I think it does a good job but having only ever done that I couldn’t tell if it genuinely did or not.
Dave!
