So, purchased an incredible find a year ago which ive gone through recommissioning.
Its now got to the point where i need to tackle the underneath, wheel arches etc, its a zero rust car that had been in a dry climate for the last 30 years (last 15 in a garage, carcooned) so jet washing is an option, i tackled the engine bay with a degreasant soak and then jet wash, which worked well but had to be very careful with protecting certain elements, labels etc to preserve its originality.

Im wondering if a steam jet wash system might be more appropriate for this next stage (was probably more appropriate for the engine bay) or get a dry ice system as theres nobody near me that offers that service.

What do you guys do when represented with a restoration like this? One thats really really caked on? no grease and oil at all, just caked on dry country dirt, like dried on thick layers of dust , if you can imagine.

Any pointers that might make it easy/er and also create an opportunity to buy more cleaning toys biggrin

A pressure wash will lift most dirt, get some bilt hamber surfex hd and mix it up in a 5 L pressure sprayer from screwfix, spray on and agitate with a brush for stubborn stuff.

What about dry ice cleaning? No idea myself but someone on the mk4 golf forum had it done

Thanks, i’ll get some..

Dry ice is a no go where i am, would have been first choice though, great results with little damage

If It's just country dirt a hosepipe with a good nozzle will remove It

Turned out to be underbody protection applied from virtually new, mixed with the dust, thought it was a bit stubborn smile

Once removed, acid cleaner, steamer and jet wash..it is unbelievably immaculate, just like its rolled off the assembly line, i guess not being exposed to anything for 15 years it literally acted as more a preserver more than a protector from road crap.

Very happy with result, its now protected again.
