Try 'Demonshine' When its a bit warmer and I feel like doing it myself, I apply a suitably diluted solution from a watering can (with rose). Always comes up a treat.

Personally I try to avoid mechanical car washes as imo they can be a bit abrasive on todays soft paint finishes. Local hand wash place (staffed by Romanians) is cheap and quick. Plue you get a card..pay for 5 washes get number 6 free. I waited three months till I used that card...boy was it minging! Came out looking great....I think they use a version of Demonshine too.

There's only one hand car wash near me (the shell petrol station I always fill up from coincidently)

They charge £5 for a 'standard' hand wash with no wax/gloss treatment. When I go down to Birmingham I an get it for £2.50

Demonshine is good stuff - you used to be able to get it in two variants, one that you add to the rinse water as previously described and the sort where you can spray it on the wet car after rinsing, rub it in with a micro-fibre mitt and leather it off to a shine.

Works ok with black plastic trim too.

Have the petrocan pass for my black MS. Completely useless right now....the back half of the car looks as if water hasn't even touched it. But winter is another story....hopefully it'll get the salt off at least.

Been using the touch less....the new ones with the moving conveyor belt and conveyor drive you park on. I hand wash once a week and use this the other days....only because I'm in a new build area with dirt all around. But in winter it'll be good to get rid of the salt at least
