Extremely stubborn caked-on brake dust

OK, just to try one more time to convince you guys, I am attaching a few posts by leading members of NOT the detailing industry per say, but those who deal with chemicals and that began in this business before we were born:



Ron from Auto International responding to and agreeing with Bud from Detail Plus.



Bud,



You give good, honest, true advice!



You and I were doing detailing when 90% of those who visit this site were still in grade school or perhaps not even born.



Yes, I was lead down the wrong path many times as I learned the business, what to use, etc and lost my cousin, who used HF in his truck wash business, to the accumlated effects of HF.



He would argue with me, etc, must like Floyd did, that if the user is careful, etc, no problems.



Well, Duke is dead, I had a distributor in Florida a few years ago, nice, smart lady, who started detailing when she was 15. She used a lot of HF, and at age 36 was in advanced stages of ostiaprosis, loss bone, in her legs, arms and back, due to the exporsure.



In the late 80's and early 90's, when I was doing the set up's and training for the AngloAmerican Auction chain, we taught the way to remove water spots from glass, the same as Gary claims to be "exclusive".



We both know, from our years of experience, working with employee's, if a screw up can happen it will.



More than once a month, in each of the 16 locations, an employee would mess up and forget, leave the HF applicator laying on either the paint or the windshield, and there went another couple hundred bucks to replace a windshield or repainting a panel.



Detailers who have not taken chemistry courses or done self study, know very little of the real dangers of many chemical components.



We in the industry, who have spent years of learning, etc attempt to provide true, honest, documented information to the detailing industry, however many times, all we get in return is "I been doing this for 4 to 10 years, etc and know all there is to know, it works for me, so I am right, etc".



As the old saying goes, "You can lead a horse to water, but you can't make them drink."



This subject is a prime example of that old saying.

From Bud,



Researching the issue of Hydroflouric Acid what I find is that chemical manufacturers typically buy a HF solution from manufacturers that is 70% HF and 30% water.







They will then blend 5% HF with Hydrocloric or Muratic Acid and a Surfactant to provide a "wheel cleaner."







This is typically ready to use. At that 5% strength it is still dangerous. It can blind if it gets in eyes; it can damage lung tissue if breathed and it can burn skin if sufficient gets on skin. Cummulatively, it penetrates the skin and goes into bones and does not "leave." Over time it can cause serious damage to bones.







We do a lot of things that seem safe and cause no problems, but when you consider the dangers of the chemical it would seem that a prudent detailer would not use it.







Certainly at the 5% concentration it can damage windows. But the bigger issue is the dangers the chemical has to a person's health.

These are leaders in the detailing industry in the form of history and product/chemical development. I wanted to show that these guys are not daily technicians with an opinion, but great resource of factual information.



HF Acid is a long term negative impact product. I am also emailing some in my network to discuss the effects on paint and glass..glass technology has changed and is not the same as it was years ago. HF Acid CAN cause etching of glass, but that should not matter. The health risks are just too great over time.

Yea, I agree that any product with HF or ABF is very dangerous. I would try TOL's Wheel Wash. Pretty strong stuff, but it does not contain the above listed acids.
 
WCD said:
Wheel Brightener is Hydrof. Acid?? Man, I would not use that stuff, ever. I did at one time, but learned more about the effects and read reports about people losing fingers over its use. It is not made by more and more manufacturers. You can not only damage wheels, but your health. I thought it was not good to use on clear coats? I remember seeing it eat right through some coated wheels years ago. To be compliant to use this stuff, you need a respirator, face shield, gloves, etc. Dude, seriously, I would try anything before that and even buy new wheels before using HF Acid.



You don't want to damage parts of your own body (that you may not see results for a long time) in order to clean some brake dust.



I know guys and just trained with some that use it still. They changed their minds like I did after educating themselves on the health aspects. I'm sure some of you use it and like it a lot..it works very well when used as directed. However, as a caring individual and someone that would hate to see this stuff mishandled, or accidently left out for a curious child to spill, my 2 cents are that you simply say, "no" to this type of cleaner.

WCD, personally I would like to thank you from the bottom of my heart!! To many times someone will recommend something and not understand it's ramifications on the health of the user or those in the surrounding area. Youth sometimes has the habit of thinking that they are indestructible, until something like this comes along ! It can hit you like a sledgehammer before you ever know there is even a problem!

Trust me, I know from direct experience ! If you don't heed these type of warnings, someday you will be writing these type of things down (if Lucky) to others just as WCD has given his experience and knowledge to you!!!!!!

Of course some of you might think things like this still will never hit you (everyone says that), because you are in awesome shape, and on the road to "nirvana", well, dream on dudes, I and thousands and thousands of others can guarantee you it can and will happen if you care to disasociate yourself with reality . Sorry to rant, but I know what I am talking about under these circumstances, perfectly!

good but, everything in life has ramifications. You can get just has hurt charging a car battery , mowing a lawn or using a blender in your home.



Some people like me will continue to use acid cleaners since there is a reason for them. Some will not and try other paths. Some will ride a bike to work to save a tree too.



PS, this topic on acids has come up many times and I sure it will in about 3 months....again.
 
ummm.....should I be scared? I have been using WB without mask or gloves. I have gotten it on my hands, but not at full strength. Actually I used it yesterday and today to get the winter grime off of my wheels from the winter. It actually ruined the chemical proof sprayer I was using. :shocked

Just dont use it on windy days. I also use it without a mask/gloves. Theres really no reason this stuff should be getting near your mouth anyways unless its a windy day. I've gotten it on my hands at 4:1 and just rinsed my hands immediately.

It doesn't make much difference whether it's diluted or not....you don't want the stuff on your skin, you don't want to breath it.

Well if it was concentrated you probably wouldn't have a hand the next day..:bolt So it does matter.

No, not with those chemicals. Read up on it.



(The damage is gradual and long-term. )
 
Background: Hydrofluoric (HF) acid, one of the strongest inorganic acids, is used mainly for industrial purposes (eg, glass etching, metal cleaning, electronics manufacturing). HF acid also may be found in home rust removers. Exposure usually is accidental and often is due to inadequate use of protective measures.



HF acid burns are a unique clinical entity. Dilute solutions deeply penetrate before dissociating, thus causing delayed injury and symptoms. Burns to the fingers and nail beds may leave the overlying nails intact, and pain may be severe with little surface abnormality.



Severe burns occur after exposure of concentrated (ie, 50% or stronger solution) HF acid to 1% or more body surface area (BSA), exposure to HF acid of any concentration to 5% or more BSA, or inhalation of HF acid fumes from a 60% or stronger solution. The vast majority of cases involve only small areas of exposure, usually on the digits.





Pathophysiology: The 2 mechanisms that cause tissue damage are corrosive burn from the free hydrogen ions and chemical burn from tissue penetration of the fluoride ions.



Fluoride ions penetrate and form insoluble salts with calcium and magnesium. Soluble salts also are formed with other cations but dissociate rapidly. Consequently, fluoride ions release, and further tissue destruction occurs.





Frequency:





In the US: More than 1000 cases of HF exposure are reported annually. Actual incidence rate is unknown.

Mortality/Morbidity:



Local effects include tissue destruction and necrosis. Burns may involve underlying bone.

Systemic fluoride ion poisoning from severe burns may be associated with hypocalcemia, hyperkalemia, hypomagnesemia, and sudden death.

Deaths have been reported from concentrated acid burns to as little as 2.5% BSA.

Sex: Males are affected more commonly, which reflects occupational patterns.



Age: The majority of exposures occur in adults.







Ammonium bifluoride (ABF) is one of the most common, and dangerous, wheel cleaners used in automatic carwashes today. Its effectiveness removing brake dust and difficult contaminants from chrome wheels is undisputed, but some chemists say ABF presents an unjustifiable and potentially lethal risk to carwash operators and their employees.

This topic I think has been covered most times then Wal-mart building stores.



he scare tatics on this is dangerous and that is like the "topic of the day". Nevermind all the chemical we use to "dress" our cars etc etc. If you read into any chemical it is bad.



Case in pint, some people like and use acid cleaners and some do not.
 
I guess my question is, what is the concentration of acid in WB without dillution?



That would give me a better idea of what we are dealing with.

Shicks, I don't know the answer to your question. I suspect Meguiars can/will provide the MSDS. The bottle I had showed a 3 out of 4 possible in the warning triangles meaning: HIGH HAZARD WARNING :)
 
I have fuel adds with 3 out of 4 on them....Hell, you can have Fingernail polish remover (MEK) or Acetone with the same. I have gallons of KILZ® Original (which I love) with the same scary 3 on it! LOL Gotta love the MFPA warnings.



Case in point, be smart about it and it only causes cancer in CA!
 
I think the point that some of you are overlooking is that when acids etc. are used in an industrial setting, there are emergency showers and eyewash stations, as well as acid spill/neutralization kits at hand. HF requires special and specific neutralization products in lieu of (or perhaps in addition to) the showers and eyewash. This is typically calcium gluconate, which provides the calcium required to neutralize the fluorine so it doesn't leach the calcium out of your bones in its effort to reach a neutral state. How many of you that use HF/ABF wheel cleaner have any wash/spill prep handy when you use/store this stuff? That's the key thing, with other acids water is enough (for flushing it out of your eyes/skin), with HF it's not.



Yes, it's diluted in WB...so was the rat poison in that pet food. Speaking for myself, as I get older, I try to simplify my life, IMO HF/ABF is a complication I can do without. I think some of the difference in opinion here is age/perspective based.



In case some of you think I am talking out my butt, I used to use HF industrially, and although generally speaking I was not the one in direct contact with it, I made the decision that it was a bit too insidious to continue using and exposing employees to, and that we would live without the brightening it provided. Myself and another gentleman went through the involved disposal procedure to neutralize and precipitate, etc.



Perhaps some of you aren't old enough or have worked in the proper industry to see people you work with die and wonder if it was that tank of this or bottle of that, that we all used to work around with no gloves or respirators that played a part in their demise.



Life is filled with risk, and we all make calculations about that risk. You gentleman are of course free to do what you want, but please pause before making remarks that might appeal to the macho instincts of some members. When other people's welfare is part of your responsibility, whether that be employees, family, or friends (even internet forum friends), it changes the calculus a bit. Remember that wheel cleaner could be found by children, it could spill and be mopped up by your wife, or could spill in your vehicle to be contacted by someone else, etc. Of course, any of us could be killed tomorrow on our way to work or on the way to the supermarket tonight.

Yeah, if you're a guy, make sure you only smoke those packs of cigarettes that cause birth defects, not the lung cancer ones!
