lt1 intake cleaning
 

How do you lt1 Bros clean the top of the intake? Mine is dirty and has oxidation... :(

Power washer.

I think my opti just had a stroke reading that lol

Tough to clean oxidation with it on the car. You can try a stiff brush but it will be time consuming and tedious.

:( FML

SimpleGreen and a scrub brush, and go EASY on getting it wet. Just scrib and damp sponge to pick up the fliuds.

I tried that a few weeks back. I think that's the first thing Simple Green didn't do an awesome job of cleaning.

"When used with caution and according to the instructions, Simple Green All-Purpose Cleaner has been safely and successfully used to clean aluminum. Simple Green All-Purpose Cleaner, Crystal Simple Green Industrial Cleaner & Degreaser, and Simple Green Pressure Washer Concentrates have been used on aircraft, automotive, industrial and consumer aluminum items for over 20 years. However, caution and common sense must be used: aluminum is a soft metal that easily corrodes with unprotected exposure to water. The aqueous-base and alkalinity of Simple Green All-Purpose Cleaner can accelerate the corrosion process. Therefore, contact times for unprotected or unpainted aluminum surfaces should be kept as brief as the job will allow - never for more than 10 minutes. Large cleaning jobs should be conducted in smaller-area stages to achieve lower contact time. Rinsing after cleaning should always be extremely thorough - paying special attention to flush out cracks and crevices to remove all Simple Green product residues. Unfinished, uncoated or unpainted aluminum cleaned with Simple Green products should receive some sort of protectant after cleaning to prevent oxidation.
Simple Green has also developed break-through water based cleaners that are safe for use on metals, plastics, rubber and high tech alloys. Extreme Simple Green Aircraft & Precision Cleaner, Pro Series Simple Green Automotive Cleaner, and Simple Green Pro HD are available on both the industrial and retail markets, respectively. These products were initially developed for the aircraft industry and extensive testing shows that they are safe and effective on a variety of metals and other sensitive surfaces even in the most extreme circumstances.

Simple Green Stainless Steel One Step Cleaner & Polish is another option for cleaning polished aluminum. This product is designed for light duty metal cleaning and polishing."

Straight from the simple green website. I would not use simple green on unprotected aluminum because of the possibility of corroding it more.

Try some 0000 steel wool to get rid of the oxidation.
