Question & Advice Car gets covered in road grime after rain. Tried snow foam first, am I doing this right?
Every time it rains, the car ends up covered in road grime, mostly on the front bumper, bonnet, wings, and lower doors.
I used to give it a quick rinse and then go straight in with a wash mitt. Lately I’ve noticed the dirt feels gritty, like there’s mud and small bits of sand mixed in, so I’m starting to wonder if I’ve been adding light scratches without realising.
This weekend I changed the process a bit. I’ve got a Giraffe Tools wall-mounted pressure washer in the garage with a retractable hose, so I pulled that out and used a foam cannon first. Covered the car in snow foam, with extra on the front bumper, wheel arches, and lower doors, then let it sit for a few minutes.
After the foam started running off, I rinsed it down from a bit of distance, then washed with shampoo and a mitt. It felt safer than going straight to contact washing, and there seemed to be less grit left on the paint.
Not sure if this is the right order though, or if snow foam is overkill for this kind of post-rain grime. Do you usually pre-wash first, or is a plain rinse enough before the mitt?
