I would like to know how many of you wash you engine bay? A memory popped into my head of when I was at a local do-it-yourself car wash and some dude was washing his engine bay out with high-pressured water. On a BRAND NEW BMW! I mean, who does that to their obviously new car? For me, I do not wash my engine due to the amount of sensitive electronics, fuses, and electrical sockets in engines these days. It's pretty risky. Older engines you were more able to get away with it. I use a damp microfiber cloth along with a Swiffer duster for hard to reach places and just dust all the parts individually every week. :)

I do, it's just part of a car wash. No pressure washer though, I use a bucket of water (with wash mitt and brush) and a normal garden hose (fan spray). The only Real care I take is around the alternator. Now, it's only needed about every 6 months or so to keep the dust down if you stay on top of an already clean engine bay. I just sold a 23y/o truck a few months back, and the engine bay looked as good when I sold it as when I bought it. Also sold a 17y/o car where lots of people remarked at how clean the engine bay was (had that stupid plastic cover like the M3, couldn't be more simple to keep looking nice).

The side benefit is that in later years when the engine needs to be worked on, it's not a massive pit of goop and crud coating every fastener and connection.

You're worried about the electronics, I'm of the opinion that if they can't handle a little water while under warranty, I want to know NOW so I can get it corrected.

Just washed mine yesterday. Lots of soapy water in a car wash gun and wiped down excess water and let set in the sun for a couple hours.

I Never use degreasers and the most I might use would be simple green. I do dress the compartment when it is dry. I also wash the hood.

My MAZDA 3 is NOT garage kept and we drive it EVERYWHERE and EVERYDAY. Living at the bottom of the California Serra Mountains RENO is only 2 hours away. During the winter going over to RENO the M3 returned home BROWN and covered in road grime and salts. the undercarriage and parts of the engine bay as well. Also travelling up and down the coast from where we live to Oregon I do not fear driving off road in dirt or gravel. So needless to say our M3 can get really dirty even the engine compartment. So as a casual rule every other exterior washing the engine get a wash down. I have already post my OCD with tire/wheel and wheel well washing on my thread. :laugh2:

^^^^good comments^^^^^
This is funny reading...often a concern on forums. The electrical connectors on most newer manufactured vehicle from about 2000 use weather seal connectors. You can almost submerge an engine and theoretically it should stay running.

I like to hand wash our cars, but use an automated car wash with undercarriage spray during the winter months to remove road salts. None of our cars are rusted out as a result. And we take our nicest/newest automobile for an annual detail each and every summer since it was 1yr old. They wash the engine bay as part of the annual detail and the engine bay looks great!

I also make sure that all our car have the full assortment of engine splash guards underneath.

My daughter's Mazda 3 didn't have slash guards and didn't have the engine bay maintained. It was gross. When I swapped out her engine (blown head gasket) with a 2.5L Fusion engine I made sure to clean the entire engine bay as best as I could with the engine out. It was a pain, but it was worth doing. And I made sure the "new" engine going back in was as clean as possible. Put on all new splash guards for her too.

I love working on clean engines. Dirty engines, BLECH!

IMO if you got the time and enjoy it go for it. Just don't use a high pressure sprayer.

For me personally I think it is a waste of my time. I love washing and maintaining my vehicles but the engine bay is purely mechanical. It can live with road grime on it. I have changed a lot of under hood parts on my cars that have never been cleaned under the hood. And there was never a time I thought I wish I had regularly washed it.

Don't get me wrong though. I love car porn pics of spotless engine bays, especially when they tuck the wires. HNNNNGHHHhhhh

This is our other "Dailey Driver" down for some upgrades and repairs. We are the second owner and it is an )( with 70k miles born in Texas and never saw a garage. Sat most of the time out on the flight line at the AFB. Covered in Texas RED dirt when we bought it. In a way it sorta preserved a t lot of the area's not generally washed like door jams and undercarriage. It took my about a year to get it to this point with lots of engine washing and also under the car while on simple RHINO Rams with soapy water simple green and brushes.

Currently I had to change a oil seal leak and decided to also replace some parts known to be problematic close to the 100k mark. These pictures were just taken so the engine is a little "dusty"...LOL

My other car which is pretty much "custom" everything I kept clean all the time. But I lived in Santa Cruz California 5 minutes walk to the boardwalk. The ocean air attacked my fasteners and other parts as well. Although they are clean they are not shiny and new looking from simply the salt air.



I should just mention that our "NEWER? MAZDA engine compartment do not like some of the common cleaners and degreaser that are on the market and even the better known ones that have been around for years. ALWAYS test a small area that will not be seen before spraying them all over the engine. And even then you may get a reaction to discoloring on the plastics. Those companies knew that was going to be a problem so many of them marketed a "SHINE" spray to dress the engine compartment up when you finished cleaning it. The problem with the "SHINE" is it looks great for showing at a car show or for a few days but attracts dirt and grime very quickly and also spot dries from the heat under the hood making the engine compartment looking rather bad. Soooooo you then spray more of the "SHINE" to compensate. Next thing you know you are addicted to the "SHINE" product so to say .LOL Just saying. The old days and as they say "OLD SCHOOL" before those "SHINE" products were available was simply to spray WD40 all over everything. :surprise:

What I use now is mainly for interior (leather loves it) but works GREAT and safe for everything under the hood.

I should also mention that I do occasionally use my pressure washer, but I adjust the PSI and use the pistol shorty to get into tight places and also is great if you are cleaning under the car on ramps.:grin2:

Years ago, I worked for a car detailer in New Jersey for a few months. I worked at a dealership that we had a contract with. We would wash the engine bay of every used car that came in and they wanted to resell. There were a lot fewer electronics in the engine bay back then though. We would also spray the engine bay down with the tire dressing after it was clean. I am sure it was a mess after a few weeks, but no one seemed to care much. lol. I don't wash the engine bay of my Mazda down. It is still new and with the covers on the engine, I can't see the dirt and grime right now anyway.

Every time I wash my car I would brush, dust, and wipe my whole engine bay. I use my car as a daily driver and it's also dusty here in my country. I have not washed the engine bay of my Mazda 3 yet as it still looks very clean and I usually wash the engine bay of my family's car every year. I've learned that by doing a simple clean up with your engine bay every time you wash your car it would keep that amazing clean look and when its time to go for an engine wash it wouldn't be too difficult.

Haha thanks! I believe you do a better job at keeping your engine bay clean than me, I've seen some of the pictures you posted and they look amazing! How often do you wash the engine bay? I do mine at least once a year for my family's car.

Ok................... the things I do for the forum and my fellow MAZDA enthusiasts!
:nerd: :grin2:
A fast spray down using only SIMPLE GREEN. NO brushing.
As it was drying I shot the rest of the car with the spray gun just to get the dust off of it. Wiping the glass and a fast soak up of water puddles on the intake and a quick wipe of other puddles around the engine bay. TOTAL time for all this was 45 minutes. The car fire and idled just fine.

Now think if this was NOT a ENTERPRISE RENTAL CAR and your own
MAZDA
. Wouldn't you spend 45 minutes for a simple engine bath? :laugh2:
