Question about Simple Green? (Already read sticky)
 

Hey fellas. I've heard many people say that Simple Green is corrosive to aluminum, but what I don't understand is, the entire block is aluminum so how can it be used?

P.S. What do many of you use to clean the intake manifold? To get all that dust and crap off?

Thanks!

Ive used simple green on everything.

Never seen an issue, personally.

Make sure the engine is cool, in shade, hit it with simple green, spray with water, hit with leaf blower or compressed air.

Agreed.

Kinda hijacking the thread, but do you need to mix it with water in a seperate spray bottle? Like a 50/50 mix?

It's pretty popular with bowlers using it on bowling equipment to remove oils. Most do a 50/50 mix of SG with 91% alcohol or 50/50 with water to dilute it. I use it straight up 100% and then apply the alcohol to help evaporate the materials quicker.

bowling or blowing? :lol:

haha I tried to avoid the word 'balls' and figured the innuendo would creep in ;P

What about for washing the outside of the car? That's what my dad always uses so it is readily available about the house and it seems to work OK but my paint is in bad enough shape as it is and if it is bad on the car then I won't use it.

I wouldn't. It's pretty harsh stuff. Stick to using car wash soap.

As for the original question, I always use a 50/50 water to SG mix and rinse THOROUGHLY when using it under the hood. I've also used it on the inner hoops of my old ZR1s with good results. For the intake, I use a microfiber applicator sponge with some Meguiars Natural Shine on it.

Personally I have used nothing but SG on my engine since it was new and always get asked how I keep it looking so clean.

Never had an issue with corrosion, but I always make sure the engine is cool and rinse with water with in 15 minutes. I use it for brake dust too.:D
