dish soap

Nonsense and nonsense. It will leave surfactant residues everywhere. It will not dry out rubbers and similar any worse than other detergent products (and notably less so than many automotive products which have strong solvents and are highly alkaline - neither of which applies to dish soap). More over, it will not dissolve metal due to high salt content. Trust me when I tell you that many bulk auto shampoos are literally the same as dish soap.

Check previous thread with my proof of principle with surfactant leaving residues which would make you 'believe' an LSP has been stripped.

My biggest concern with dawn was the problems it can have on other parts of the car. A ingredient in dawn is protease. Protease is a corrosive digestive enzyme found in the pancreas. This same enzyme (along with a few more) is found in bird bombs, which we all know can have a negative effect on paint. All I'm saying is I am not gonna use it.[/QUOTE]
 
I don't use dawn b/c its too rough on trim & rubber.

I've heard that bird-poop/bombs contain high levels of urea and guanine...but never protease.
Didn't realize that it, too, may cause CC-damage. Thanks for the info, (I suppose...:eek:).

-Too bad that Urea and Guanine are said to be harmful to auto-paints...
They are supposed to be an integral part of the Human-skin's natural moisturizing, as well as "sparkly"...factors (NMF).

I've never tried it...Never will!!...But:
As some will say (in Japanese):"uguisu no fun"!!

:D

Where did you read that protease was a key in causing damage? Are you aware of the proportions it is present? Do you realise that many vehicle care products have ingredients which are used in paint strippers - but they are present at low levels so are not a significant concern? It is important to keep perspective. The requirements of dish soap are such that mildness is much much more critical than for car care products. If a dish soap was even slightly corrosive, people would end up with skin irritations, cutlery would be marked and damaged, pipework would corrode... etc. I would be reasonably confident that a scientific test of car care products would show that 9 out of 10 would be more, not less, of a hazard than dish soap.
 
This and PIPUK's LSP stripping thread are very informative. Good news is I don't have to buy Dawn any more (except for when I do dishes, which is almost never :laughing:).

Bad news is, I now have to look into getting an actual paint cleaner for stripping LSPs. I already have Optimum Power Clean which I've read can be used to strip LSPs but I'm unsure if that's true. PoliSeal's another option but buffing an entire car just to strip LSP would be very time consuming. I'd much prefer a spray & wipe or shampoo & wash bucket option. :help:

This argument about dish detergent has been around for years. Again all I am saying is its not for me. I have found in the past that over time dish soap has not benefited me getting to my goals when detailing cars and maintaining trim etc. Dish soap is made to act like a detergent and degreaser. Nuba is a wax which in turn is not detergent proof, unless in products like coly 845 (which uses other ingredients) or products similar. I have used dawn in past past past, after using it the paint is squeaky clean. This is great for dishes. Oils added or natural on paint trim etc can be stripped using detergents and degreasers. I'm not saying that protease is the only culprit. But when in combo who knows. Here is an older article from BASF testing. It mentions bird droppings and enzymes that it contain.

Not all of P&G's dish-washing liquids contain protease.

I wonder if one of those is the one that "The Z's" spokesperson would be recommending...

:dunno:

Bob
 
Why always Dawn?
P&G has many other dish washing liquids to choose from.

I've always used Ivory Liquid in place of Dawn...
And it's not for "stripping" purposes!

No worry about harmful-enzymes either!! http://www.hescoinc.com/msds/pg-46173.pdf

Try it sometime...

I use dish soap all the time in my kitchen. I use it to wash my hands. I never use it only my cars, because:

Its not strong enough to strip sealants, and there are soaps available that will easily strip waxes.

I don't know of any automobile manufacturer who recommends washing their cars with dish soap.
 
One thing I DO USE dish soap for is getting in those little edges. Like around where the rubber meets the glass, emblems/badges, those pesky areas where dirt collects and sticks. Sometimes ya just need something with a little more oomph 'car soap' but not a full blown APC.

Just my 2¢...

To be honest, if what I have presented previously is not convincing about the lack or harm, there is little point my persisting.

Of course P&G won't advise using their product in an untested situation - all it takes is one idiot to claim that the product did harm and they are into compensation because they have never tested it and were daft enough to say it was safe without having done so. Enzymes - jees these are the safe alternatives out there! Yeah, bird droppings will contain them (who knew that the digestive system, containing digestive enzymes, might have sent a few out the far end...) but they are not the primary cause of damage. Meanwhile, most people will be using dangerous chemicals (you know, the ones that enzymes replace in 'safe' products) on their vehicles without a second thought (just look at the abundance of sodium hydroxide - aka, drain unblocker - in products, especially in the UK).

Let me finish off with a bit of fact. I have worked in several chemical manufacturers and know for fact that certain surfactant blends will be sold to both dish washing and car washing sectors - same product, different label. More than that, I can also tell you for fact that certain products of this type are well reviewed by detailers on independent detailing forums.
 
I get what you are saying , have from the beginning. I posted my opposition and reasons for it. Again as I have said from get go " I don't care what you use. It's not for me". The enzymes were not the deal breaker. The entire dish detergent is! Hell you said it yourself, they aren't going to tell us to use dawn on something like a car that it hasn't been tested on. Sc Johnson makes a great paste wood wax, but its not going on my car. I'll stick to what I'm comfortable with and agree to disagree.
 
Amazing what a simple question I thought I asked and now come back to read all this. WOW LOLOLOLOL
