Default Engine Bay Cleaning

Hello,

1. what is everyone using to clean the engine bay no need for the harsh chemicals as it will eat away most rubber, hoses, spark plug wires/caps etc?

2. best way to clean the rust on the brake power booster?

Thanks for the help

GM Engine Shampoo is the best product I have found. Only real solution to the rust on the brake booster is to have it rebuilt and replated. Paint is a decent fix if original finish isn't important to you.

Hi s,
"(2.)".....
Depending on the year of the car the brake booster may have been painted gloss black and not plated. This makes restoring a rusted booster a bit more straight forward.

To restore the appearance of a rusted booster I'd remove as much rust as possible by hand, then use wire brushes, and finally a paste type rust remover.

Then the booster can be painted gloss black, or if the booster was originally di-chromate washed zinc plating, painted with one of the paints that mimics the plated appearance, or send it off to be re-plated.

Regards,
Alan

I don't think there's any 'magic' to cleaning the engine compartment... it takes work, work, work.....time, time, time.

Don't listen to him. Alan 71 has clearly sold his soul to the devil in return for his car staying perpetually clean. Its the only possible explanation.

car is 1977 with approximatlely 32,000 miles Iam the 2nd owner so I don't know if what is on the car the factory installed booster or if the previous owner had it replaced which I do not think so due to the milage on the car when I purchased it, but I could be wrong and anything is possible.


Thanks for the help

Hi,
I believe 77 cars typically had a booster that was originally plated.
So if you don't want to get involved with having the booster re-plated painting it with a gold/copper colored paint is a nice option.
Regards,
Alan

Here's an example of a part that was originally plated with an attempt to mimic the appearance of the plating using paint.

I use Dawn DISH DETERGENT and water to clean the engine compartment. It works well. It will remove most oils and grease so be careful after a good wash.

On my classic truck I used Simple Green diluted a lot. It also works well and will remove most dirt and grease.

Depending on which car wax you use they can remove the car wax.

I like the diluted simple green as it seems pretty gentile to original finishes while still getting the grunge off.
