Defacto Zano prep, advise from Sal

All Dawn does is strip or remove oils and grease as it is intended. It just gets into tiny spaces to strip wax/oil/grease better than other wash items. However, it will leave a film if used too much or too often, that's all. The PH of Dawn is alkaline enough just to remove stuff such as this. It should not effect Zaino or other Polys. You'd get the film thinking you damaged it, but it's just that, a soap film from Dawn which can be removed with another wash product or a QD if needed. You want to neutralize the alkalinity of the Dawn film, and the best way is washing with Z7 or other product.



You can use Z7 wash to strip oils as well, but doesn't get in the tiny areas long enough to do the oil removals, on the finish it will, but door jams and such, it may and it may not.



If you have no protection on the finish and continue to wash with Dawn, over time it can lead to problems, but you'd see the film first and wonder why it looks so bad.



The whole idea behind all this is to remove all impurities B4 you apply a poly product such as Zaino or others so the finish is as virgin as possible for proper bond. Once it's applied, there would be no reason to wash with Dawn unless you're stripping a wax topper off and want to add another coat of Zaino. Otherwise, use the Z7 or whatever good car wash product you have to maintain the finish.



No big deal, No one really continuously washes their car with Dawn. It's a one-time item used just for that purpose.

Deanski,



I disagree with your position but that is based on my experience. A freshly coated waxed car with a 1 day cure may not be entirely removed by a single dawn wash. Many people have experienced that here. It can take 2 or 3 washes to completely remove a top quality, properly applied and cured wax layer. If a single wash could remove that protection layer, waxing would hardly be worth it. However, as time goes by, the wax layer deteriorates (2-3 weeks depending on your area and exposure to the elements), then perhaps a dawn wash will strip the wax.



Hence the recommendation by some of us for the use of a "proper" wax removal product such as a APC diluted to the proper ratio, Prepsol etc.



In fact, Dawn is probably not even the harsest dish detergent. Sunlight or Ivory may even do a better job then Dawn.



This whole Dawn movement is a result of Sal's recommendation and probably some misinformation floating around. I for one, really like Zaino. That said, I have completed dawn washes and found them not to be any more useful than a standard wash. I don't believe Sal should be prompting Dawn specifically unless of course, he's getting a kick back for it. God know's, his recommendation has lead to an increase in Dawn sales. I am actually surprised he doesn't say to use a wax removal product rather any product by name.



Dawn is meant and should stay in the kitchen.



People should be instructed to use quality products like Meguiars APC, 3M's APC, EF HI diluted to the right ratio for wax removal.



As for Dawn damaging the clear. Repeat use on non protected cars can and will lead to damage. However, if you maintain your vehicle's finish properly, the occasional dish detergent wash shouldn't harm your clear.



As for your comment, there are a great many people who actually use dish detergent as a regular wash soap. Mainly because of ignorance but they hear about it being used by individuals like us, not understanding that it's meant to be used as part of entire system.
 
Gee, then I better stop washing my Le Cruset pots which are enamel coated in Dawn huh? Oh yea, the floor too? All my appliances? Come on.... GMAB! :rolleyes:



If anything, Dawn will leave a film on the finish if used in large amounts and not rinsed fully or if finish is hot. Maybe you better stop using that green Scotch-Brite pad when you wash the finish on a car with Dawn! Leave THAT in the kitchen.



If any dish detergent were so alkaline enough to damage paint, no one would be able to handle it W/O rubber gloves, and I don't mean the thin Latex.



I'd love to see an actual sample of Dawn "damage" to a paint finish on a vehicle or other painted items for that matter.



Yes carnuba is tuff, but in all actuality, it's the oils/silicone that wax has as a binder and that's what you want off the finish.



We could use prepsol and other prep solvents, but some people do not have access to this product. It's easy for someone to use a known detergent to assist in removing oils/grease/silicones.



Anyway, for the most part, it's used for post-polish strip of oils/silicones, not so much umpteen layers of wax.



Gotta go... wife about to immerse pots in Dawn and I have to stop her.. ;)



Have a nice day!

Anyway, if you comfortable using it.... by all means go ahead :up



Myself, I'd rather error on the side of caution ...



I have seen floors damaged by dish washing detergent (stop by my mother's place and have a look at her vinyl kitchen floor in the basement).



I have also seen tile finishes effected by dish detergent use.



Stop by any reputable floor and tile gallery and I'll guarantee that they say the same. I've just moved into a newly constructed home, when I asked them about the proper maintance my tiles, there were very clear to only use a commercially prepared wash that was pH neutral or else the finish could be stripped! I already new that from my watching what happened at my parents home but I wanted feedback on what was the best cleaner.



Pots/Pans - I sure hope they are more durable and able to withstand Dawn as opposed to a clearcoat. Considering the sponges, scouring pads that are used on them. I can't believe I am going to go into this but that fact that we BAKE with them at huge temperatures and use very acidic ingredients, I sure hope they can withstand a dawn washing! I can't say the same about my clearcoat! :rolleyes:



I wouldn't compare a vehicle's finish to that of an enamel baked finish but hey to each his own :cool: And as for using it on floors, yeah, I wouldn't. !!!
