Jk-boi Posted April 5, 2017 Share Posted April 5, 2017 So I've got some autofinesse verso which was suggested by a friend who said it worked pretty well cleaning his engine bay, he diluted it down 2:1 then got in there with a brush, and too finish clean it off with his jet washer. Even the auto finesse how to guide shows a jetwash I know modern engines are covered in plastic covers and wired connectors all sealed but surely blasting any water be it garden hose or jet wash will get into places you don't want water sitting? Anyone done this????? I may just go with what I've searched on here and just remove everything with microfibres as I'm too scared to blast water into my bay lol 1 Quote Link to comment Share on other sites More sharing options...
Strudul Posted April 5, 2017 Share Posted April 5, 2017 Not done it personally, but supposed to be fine. Just cover your alternator and battery. Quote Link to comment Share on other sites More sharing options...
Rbailey182 Posted April 5, 2017 Share Posted April 5, 2017 I have done it and would have spent a small fortune on carrier bags had I not stock piled them. I probably covered more than I needed to but better to be safe. I didn't have any issues afterwards apart from getting the bags back out after I had worked them into some really tight areas.

marzman Posted April 5, 2017 Share Posted April 5, 2017 I did this on my G-Wagen. It completely killed it. Covered anything sensitive meticulously, but it would never turn over again after that. Killed the starter motor somehow. Quote Link to comment Share on other sites More sharing options...

coldel Posted April 5, 2017 Share Posted April 5, 2017 Go drive in the rain for half an hour and open the bonnet, generally find plenty of water on engine bay parts - I have seen lots of videos of people lightly jetwashing engine bays, not done it myself though Quote Link to comment Share on other sites More sharing options...
Jk-boi Posted April 5, 2017 Author Share Posted April 5, 2017 Thanks for the replies guys! Might just give it a light rinse with hose instead Quote Link to comment Share on other sites More sharing options...
Stutopia Posted April 5, 2017 Share Posted April 5, 2017 I just did the BRZ, didn't pressure wash though, just sprayed degreaser, agitated with a brush, then used the spray setting on the hose gun to rinse. I didn't bag anything off, just used my eyes and stayed well clear of the alternator, ECU, battery, fuse box. You don't need much to rinse away dirt if you've agitated first, certainly not lbs of pressure. 1 Quote Link to comment Share on other sites More sharing options...
xscotteex Posted April 6, 2017 Share Posted April 6, 2017 When I cleaned mine up it was a case of working the solution and degreaser in with a brush, letting it dwell, then rinsing. If the degreaser is doing its job you shouldn't need to jetwash Quote Link to comment Share on other sites More sharing options...
Strudul Posted April 6, 2017 Share Posted April 6, 2017 My bay was so filthy that no amount of degreaser (or home jetwash) would clean it. Resorted to scraping the dirt off Quote Link to comment Share on other sites More sharing options...
rabbitstew Posted April 6, 2017 Share Posted April 6, 2017 I have never been brave enough to jet wash an engine bay. I think it mainly stems from my classic mini days when any little bit of water would cause the car not to start. I used to dread rainy days. In fact a popular mod back in the day was to cut the ends of the fingers of a marigold glove and then stick it over the distributor, feeding each lead through a "finger" in an effort to stop any water getting to it. I usually just use some engine degreaser on hard dirt, then wash it off with petrol. Quote Link to comment Share on other sites More sharing options...
