I have used the Waves one in Tesco car park
they seem to do a good job and worth it if the inside is a mess (I blame the grand kids!)
but only once or twice a year - and normally when it is cold out
I worry about using the car wash places elsewhere as I see a lot of things in the press about Police raids and finding all sorts of dodgy practices - such as modern slavery and stuff.
I presume - possible naively - that Tesco would not allow them to use their spaces if they were not sure they were clean (sorry!!)
but most of the time I just do it myself with a bucket, sponge and hosepipe
Sponge or noodle cloth?
Sponges tent to scrape any muck across the bodywork.
I occasionally do a “mini-valet” for ours: snowfoam to loosen much, jetwash, then bucket and noodle glove (Kent wash noodle or similar) to wash. Always be sure to do the door shuts for that pro finish.
Towel off with microfleece, then usually some Bouncers Done & Dusted, a QD (quick detailer) to give a fast shine to it.
Then onto the inside, for a full hoover and some Poorboys natural look interior dressing.
Sorry, did you nod off there? 🤣
I think I’m a frustrated detailer….although I would quickly get bored doing other peoples cars 😳
