London drivers - Car washing advice

[annie90]

Just wondering if any drivers based in the London area could give me advice on where to go for a hand wash, preferable using the two bucket method?

Doing it myself is not an options with where I live.

I drive a black car and was told to avoid any automatic car washes and they can cause little swirls which can show up a lot on black paint.

I'd be looking for somewhere around North or West London.

Thanks in advance.
