Underside Restoration - Do I need a Steam Cleaner?

[scz4]

Evening,

I have just bought a 2009 MX-5 with 33k miles as a project and something to tinker with. As any MX-5 owner will know, the undersides don't have much in the way of protection so have a lot of surface corrosion.

I plan to jet wash the underside, use a wire brush before applying rust treatment (Aquasteel) and Dinitrol protection.

Seems a lot of professional services mention steam cleaning the underside as part of the process. Is it worth doing this. If so, can anyone recommend a make and model to buy. Could maybe rent one depending on prices.

Morning.

Thanks for that. Yes, meant to add that as a step. Planning to use Gunk (or similar product) with a firm bristled detailing brush.

Having seen cars being professionally dinitroled (had a car done a few years ago) I'd suggest you need to consider how you are going to access the underside whilst cleaning it.

The professionals put it on a ramp for the steam cleaning. I've heard of people using inspection pits, but even if you can get it up on cribbing at home it's going to be pretty unpleasant lying in a puddle with the crap going all over you.

Fully expecting it to be a dirty job, but that's half the fun. You have reminded me though that I'll need a shorter lance on the pressure washer due to the limited height.

One think I will say, is that engine degreaser in the eye is a seriously painful experience.

Maybe good use of PPE, and don't expect to be able to do it lying down under the car, oh and make sure you have some eye wash on site and are not alone!

Ask me how I know......

Yikes. Will get a pair of goggles I think, even for when brushing off any rust. Don't want that in your eyes either.
