Who is correct?

@@Ashurus go for detail guardz, the cg's doesn't even let some of dirts goes through hole. Even better go for Grant's grit guard

Glad you are!

So which one ? :)

Thanks! That's exactly what I hate too when people say they don't like it because it doesn't "feel good". These products are made with science not feelings. Everything can be measured and tested in some capacity and I want people to make informed decisions on that information.

Well some of it would be ok to listen to when I describe the features and the conclusion. The main part of the video is for watching the grit guards react when I put stuff in them. If you only watch a small amount, the coolest part is the dye test that's about 15 minutes from the end.

I was hoping at least one person would get a laugh out of that

No, that's incorrect. It was controlled more than enough - to arrive at a pre-determined outcome. He needs people to "buy the winner" as the video description states. Hence why the method didn't resemble the normal mitt cleaning procedure, in any way, and he was constantly pumping the water aggressively to achieve the desired outcome. It's a cynical and dishonest marketing ploy imho. Many professional companies that detail high-end supercars & hypercars, (eg; esoteric), swear by the two bucket method with single grit guards. That tells me that it's completely safe if used properly. Although in all fairness, for the average person, the one bucket, multi cloth/mitt method is more appropriate for many reasons, it can be just as risky.

Source Garage it would be cool to see how the 7$ wal mart grit guard holds up to the others.

@@92SC300TT It looks very similar to the original grit guard so I'm guessing it would do just as poorly.

They are for sale on my site thesourcegarage.com

do you have a detail guardz dirt lock? the tabs on the bottom are very maleable and can be reshaped. Put some weight on top of them overnight and pull the tabs out a bit so they stick out. In the morning they will be solidly locked in a sticking out position to push up harder against the edges and stay in place.

That would work almost the same as using just the cyclone because the grit guard does almost nothing. The grit guard would help prevent rubbing your Mitt on the bottom and sucking things up through the cyclone, but that is about all I can think of.

Source Garage Hi Sam, I’m referring to the detail guardz dirt lock stacked on top of the cyclone... or are you referring to that?

@@bio10155 sorry you said "grit guardz" initially so I thought you mean the grot guard. Putting the dirt lock on top of the cyclone I think would give minimal benefit over just using the dirt lock. It may help keep things down a little better by adding the cyclone as another layer, but the dirt lock already does a very good job at that. If you have both I wouldn't hurt to use them both, but i wouldn't buy a cyclone if you already have the dirt lock.

But he's not selling the chemical guys one. He's selling "the winner" as the description states. The 'winner' he chose.

I agree with the multi mitt method being the best way to ensure you don't reapply contaminates to the surface more than necessary.

But he wasn't scrubbing the mitt, he was pumping his hand up and down for some reason :/

The moral of the story, imho, is to question everything and not naively believe the information that's presented, without question. Which in this case, imho, was clearly to arrive at a pre-determined outcome. Hence why the method didn't resemble the normal mitt cleaning procedure, in any way, and he was constantly pumping the water aggressively to achieve the desired outcome. Many big, professional companies that detail high-end supercars & hypercars, (eg; esoteric), swear by the two bucket method with single grit guards. That tells me that it's relatively safe if used properly. Although in all fairness, for the average person, the one bucket, multi cloth/mitt method is more appropriate for many reasons, it can be just as risky. In both cases, it's only as reliable as the person that's doing it.

that's excessive............not even when you take a bath you use so many towels, is just a car dude.....maybe u own a ferrari that you want to show off

@@elitechen5918 You should go buy a grit guard then. When my car remains scratch free and you can't understand why your finish is full of swirls, you'll have your answer. Until then, I could care less if you think my process is excessive.

@unisoulja6227 The point of the test is to see if grit guards prevent dirt particles from rising up from the bottom. Pumping is the worst case scenario, as it applies the most force. It also correctly simulates how these are used as you're inserting and removing your wash media and hand in and out of the bucket. This wasn't about how to "best" rinse your particular media, that's not what's being tested.

@Vanhamj1 If you're contact washing your car, it will never remain "scratch free". All contact washing will eventually leave marks, swirls, scratches, etc. You can help minimize it, but you'll never prevent it. Even with your supposed "scratch free" method...as soon as you lay your media down on the paint and move it, you're dragging some particles along, in contact with the finish. Regardless of whether the media came out of your clean bucket, and never went back in. The dirt is on the car to begin with. The important thing is to use quality media, and quality soap/shampoo, you can do 1 bucket, 2 bucket, 3, 4 , 5, whatever makes you happy. As long as the actual wash method is similar, the results will be similar.

Thanks for the input. I will try that and post an update video if it makes a significant difference. I had not thought of that.

Watch the last 10 minutes for a summary. Tl;dr Mesh bad, Detail Guardz Dirt Lock wins

Source Garage thank you! I did watch it. Great video. What do you have planned to test next?

@@sarbjotsingh8269 I have several things I'm working on. Next will probably wash mitts and the one bucket method vs two and I'd like to get into spray bottle analysis. I also have a ton of wheel cleaners and tools. Check out my intro video for an overview of a lot of what I have right now I'm working on.

Shut up

Grow a brain dude...jesus. The point of this test is to see how the dirt behaves with the grit guards in place. Do they actually prevent dirt particles from rising back up from the bucket floor. Not how to best rinse your particular wash media. The pumping action simulates the worst case scenario where the most force is applied to the dirt potentially having it rise back to the top. Btw...Detail Guardz specifically sells a pump attachment that you use to pump your wash media up and down on, to better rinse it. Along with wall inserts to rub it on. Bottom line, again, is the point of all this is to prevent the dirt from rising from the pumping action of inserting and removing something in the bucket. So yes...pumping is the correct test methodology.

as a side note you should take some inspiration from Project Farms as he gives you the information quick and to the point and explains as he does the tests.

First off let me say how much I love what Forensic Detailing does. He is absolutely an inspiration to me and what I am trying to do. However, I disagreed with his analysis of grit guards and thought I could do a better one. Just because we both filmed material in a bucket with a grit guard does not mean I am trying to steal hist content. I am simply talking on the same topic in my own way as many other do. I came to a different conclusion than him and presented what I feel was a much more complete analysis of the products and how they work.

Your overview of how fallout removers work is literally identical to his one bro. not saying your copying his results just his ideas and methods. hey keep going though im just saying it how I see it.

@@rodrigomx192 why does it matter to you?

It was necessary for him to repeat John’s test. It is important for an experiment to be repeated many times until the results begin to come out consistently. Only Then will you begin to approach an approximation of the truth.

@@TMZTucson maybe he feels aggrieved that he spent an hour of his time watching what he believes to be a carbon copy of something he's already spent time watching?

1. I didn't start selling the grit guard until nearly 6 months after this video. I had no intention of selling it even. The company who makes it reached out to me. 2. The point of a grit guard is to clean out your mitt, but they also all claim to keep contaminants in the bottom of your bucket so you don't reintroduce contaminants to your mitt that you would then drag back on the paint. The point of the video was to show turbulent water kicks up all of these contaminants through the basic grit guard and that its claims of keep contaminants down is completely inaccurate. The hand pumping was to generate maximum turbulence in an upward direction to pull contaminants. It clearly helped demonstrate which products worked and which didn't. 3. I have also since said that I do not even recommend the grit guard for washing purposes as there are too many contaminants floating around in the water no matter the guard used. I recommend the multi mitt method and only use a grit guard of any kind now with my rinseless washes to help clean out sponges.

@@SourceGarage Ok, thank you for taking the time to reply. Most You-tubers don't address criticism, that's why I've become quite suspicious and cynical. I apologise for my (wrong) assumptions about your intentions. That was wrong of me, and I accept there was no nefarious ulterior motive on your part. Accordingly, I will edit/delete my replies to other posters' comments. I do however still disagree with the purpose of your experiment. The actions you perform are obviously going to create the resulting reactions, it's basic physics. I don't believe any grit guard manufacturer would recommend anyone employ this method. If the proper method is used, then I believe there is very little risk. So you're not recreating an accurate scenario to draw you're conclusion from. Do they claim that it keeps "ALL" contaminants down? Because, unless they do, then your assertion that "its claims of keep contaminants down is completely inaccurate" is utterly wrong. That may seem pedantic, but that's how marketing works isn't it, hence the phrase "buyer beware" (caveat emptor). I think the point of grit-guards, like most other tools and techniques, is to minimise scratches, not eliminate them. Nothing is capable of doing that, not even the one bucket, multi-mitt method, because, (at the very least), the human element cannot be accounted for in any meaningful way.
