I've just aquired a hem hem --jeep--and I need to clean the engine and engine bay generaly , is there any kind of spray on hose off type of product around that will do the job that anyone knows of ? it's not just a deagreaser thing it's more general ---well--muck or is this going to be a get out the rag bag and go skin some knuckles time ?

Get along to the $2.00 shop and buy a dozen cans of there degreaser

Also get a paint scraper and fined some elbow grease U will need it

there NO short cut method unless you can dip the whole car in a tank

yeah i did the same thing with my.... mainstream car too
working on a farm with lots of nice muddy dirt roads the engine bay was looking like that of a rally car
a $2can of engine bay degreaser from crazy clarkes and a pressure clean with the karcher and nearly as good as a used caryard job LOL

just cover the dizzy with a plastic bag and dont hit the fuel injection to hard with the pressure cleaner

yeah, pressure cleaners are good, can do it at a carwash using their high pressure as long as you seal soem of the electrics.

Handy Hint from an ex car detailer (had my own business for 14 years)

Use a pressure cleaner of some sort(hotter the better but cold can work) and plenty of degreaser if really oily, but make sure you have a compressor and CRC handy to blow out electrical connections. They metal work eg under the hood etc will need to be cleaned by hand with chemical or polish for that finishing touch.

Use a whisk broom (the one off the dustpan and broom) is really hot sudsy water after the spray on degreaser, give everything you can reach a good scrub with the suds.

Use silicon spray on all the plastics first (whilst still dirty), clean, then spray again for a deeper longer lasting shine Otherwise wait a day for all the water to be out of the surface of the plastic.
