whats the best way of cleaning the undercarriage? just noticed some rust and crud on subframes and nuts bolts etc
Any good ideas?

No good ideas, but plenty of jokes about cleaning your undercarriage and nuts!

I know someone posted on here about a trolley brush type thing you connected to a hose or pressure washer and you wheeled it about under the car.

Not tried one, but it would get mud etc off.

You’d have to get more hands on I think if you want to treat any surface rust etc.

Off road height.

Spray degreaser mixed with hot water from a garden sprayer

Pressure wash off with one that has a 45-90 degree elbow attachment? Mine does.

--> next time you service something underneath, pick a new spot, grab a brush, degreaser and brake cleaner and spend 5 mins giving that area a good old scrub. All my sub frames are clean now and all the road grime on the gearbox is also now gone, through doing 5 mins here and there. 2015 Range Rover Autobiography 4.4 SDV8

when i did mine i did have a 4 post ramp at hand in the workshop and took me a couple of weeks to clean it all down
i used a lot of wire brush items that fits in to a drill and just keep going over and take your time when you have a area done spray or paint on some of the many types of rust removal types of spray or paint . and then i used a lot of wax oil items through a schultz gun and put a lot on over to days i put on over 30 ltrs of protection under side and in side box sections etc .when i put it in for my first mot they could not believe how good the underside was looking i think they said wow what a job . but then i have been doing cars and spraying all my life that could have something to do with it i suppose i say if you are going to do something do it to the very best you can. i used a lot of pure 15 items which is acid base after cleaning down with wire items new vehicle purchase

I think oggy has hit the nail on the head, there really is no short, easy way to do this properly, like a lot of jobs, at the end of the day it involves lots of time and elbow grease

I’ve just done mine. There’s no quick way to do it.

I removed my subframe, wishbones, etc and sent them away for shot blasting before using Bilt Hamber Epoxy Mastic to paint it.

If you’ve got access to a ramp you might be able to do it in situ but working underneath it whilst lying on your back will not be easy nor a pleasant job.
