You down with OPT? Optimum FerreX Tested & Reviewed!

[wytstang]

Does this product have to be hosed off? I do a rinse less wash only with no access to a hose. I would like to try this on my white rims (especially the barrels) as they are contaminated with brake particles. Clay bar helps but would like to try either Iron X or Opt FerreX.

How can this be pH balanced if it removes wax?

A claim that a product is "pH balanced"...
is more marketing tool than useful information.

Roughly how much product is used on a car that size?

I've never done iron removal on my cars and am curious how far one bottle will take me.

Great review and article Nick! I enjoy reading your articles a lot.

I'm glad to hear that nothing happened when you let the product dry.

I can't believe you don't have any problems washing in the sun. I have problems washing in the sun even during winter here in AZ... The water just dries way too fast.

Thanks Marc, I have a feeling you will really like FerreX. It's a great product, especially if you're cleaning a very dirt, neglected vehicle.

It should be hosed off to flush any product out of cracks and crevices were it can hide. If you work in a concentrated area, then I don't see a problem wiping it off with a damp microfiber towel.

I used about a third of the bottle, and I did the entire car including wheels.

Next question, Iron X description says that bare metal (like brake calipers & wheel balancing weights) should be covered. I don't see this warning for Opt. description so Opt. can be used on bare metal? In other words I don't have to cover the brake calipers if I used Ferrex on wheels?

Great question. In this introduction, I noticed the exposed calipers and rotors and wondered what would happen if they were hit by this product.

Optimum FerreX is safe on all exterior surfaces. You just want to make sure wheels and brake rotors are COOL to the touch. Never spare FerreX onto a hot surface.

Thanks for the review Nick. I'll definitely be adding this to my next order!

Nick -

In the pic of you washing the car, was that you washing OFF the Ferrex or did you rinse it off first and then wash the car? It looks like the product is still on the wheels, so it is difficult to tell if you rinsed the car first or went straight to washing.

I know that you can agitate the product with a sponge or whatever. Did you do that or just spray and dwell?

Thanks!

I tested it both ways:

On one half the car, I sprayed Optimum FerreX directly onto the paint before washing it. This the opposite of what you normally do with an iron remover. The reason I did this is to test FerreX's ability to remove year's of built up dirt and grime.

Oh, and just because the owner said "do whatever you want with my car," I also intentionally let FerreX dry on the surface (another BIG no no with this type of product) just to see what would happen.

Excluding the wheel featured in the article that I cleaned with the Speed Master Brush, I actually let it dry on the other wheels. It washed right off without inflicting any damage.
