HI to everyone ... Bringing this to the forum... Please post your comments or DIY and photos
I understand that a clean engine performed better than a dirty one , looking for you to share your experience and wisdom

 

I've seen detailing shops using an airbrush gun shooting air to get into the crevices of the engine.

 

I would use P21s Total Auto Wash http://p21s.com/products/bis_taw.html or http://www.detailedimage.com/P21S-M1...000-ml-Kit-S1/ (since its safe for aluminum, rubber, wire harness, plastic, paint) use brushes and just a garden hose. No need for a pressure washer. if you have a air compressor blow out the water with air. Then use 303 http://www.detailedimage.com/303-M2/...-P12/16-oz-S1/ on all rubber and plastic parts. The engine will look like new!

 

I've heard both that and engine will perform better and that it makes no difference to the engine. Which one is true?

 

The only thing that will make a engine perform better is a tune up. Spark plugs, new air cleaner and a high grade gas like shell. Cleaning an engine will not cause the engine to perform better.

 

I use a tooth brush and Simple Green, and then carefully rinse using my hose nozzle at a low volume rinse spray setting.

To keep my engine from getting dirt buildup, I detail it with a damp hand towel usually before I wash the car.

 

Never use simple green. It corrodes aluminum.

 

If you use Simple green you need to rinse, rinse, rinse, rinse! Simple Green will corrode aluminum, deteriorate rubber and plastic and stain paint if not rinsed well.

 

Correct. I think maybe OP is confusing cleaning the engine exterior with products or gasoline brands that claim to clean the engine's interior.

Even so, I like the engine to look reasonably clean. I just wipe down accessible areas with a bit of spray detailer on a rag.

 

You might be correct.

Enro, can you explain your question. It will be easier for us to help you.

 

Here is a step by step with pics on how to clean an engine:

Your car will run much better if you clean the exterior block with dawn soap and a medium toothbrush.

 

I don't worry about it. Actually, I just baby-wipe it down so it looks okay if someone does ask to see inside.

 

Why?

 

Huh?
