Is there a dishwashing powder available that will not etch glassware?
Becky from Lexington, OH
I just had my dishwasher repaired 12/08 and the repair man told me to only use Cascade Complete....no lemon and powder only. My dishes look the best they ever have. I used to use generic all the time swearing that it didn't matter. Wrong-o! It has made the world of difference for me.
The etching isn't from hard water , it's from the dish washing detergent. That stuff is very caustic. The only one that won't etch glass is Cascade. Hard water may stain glass which can be removed,.
It seems like there are so many varying opinions on what causes the etching ranging from bartenders to University Extensions.
I think it is a number of factors that cause the etching but I disagree with those who said water isn't part of the problem. I live in an area with a lot of minerals in the water and it builds up not only in the dishwasher and on my glassware but in the sinks and tubs. I have a glass shower surround that has some etching - even though I squeegee it after every shower.
That's why I use inexpensive glassware for day to day use and only use my "nice" glassware on special occasions (which I hand wash). I just replaced my drinking glasses due to etching - they looked like they were dirty and it was very unappealing.
I have been in the cleaning buissness for 30 years , and each time my clients had the problem of their drinking glasses being etched - like the finish had come off the glasses leaving a white dull finish. I noticed they were all using Cascade.
I live in Florida and have well water. I've tried different detergents, had a water softener, it quit, then had hard water. Didn't matter. Soft water, hard water, powder, liquid detergent - it all etched my glassware.
There is one call Starbright by Lanosoft. Expensive but it does not etch glassware in softened water conditions
The problem is not the detergent; etching is from hard water. You could look for a dishwasher detergent that has a water softening or conditioning agent in it.
I use a variety of dishwashing detergents, mostly Calgon because it seems to work well in the water that I have, which is softened. I wonder if it is a water problem rather than a detergent problem. I also have a couple of old glasses that look etched, but every other glass is fine. Durlex glasses used to cloud up from hard water when regular glasses were fine. If it is a hard water problem, you can put about a half to a full cup of water in the last rinse. This worked for me when I didn't have soft water.
I have soft water and still get etching, so it's not the water! But thanks for asking the question because now I'll try the Cascade too!
I have used Cascade Complete for almost a year now. Used regular Cascade before that.
Believe me it won't stop the etching.
Sam's Club Inferior Products
When I moved to Idaho Falls, ID seven years ago I started shopping at the Sam's Club nearby because they do have some lower prices on some of the items they sell, but not all. One of the things I started buying and using for the past seven years was their Members Mark dish washing powder, #244536A. I wrongfully assumed, if Sam's Club was selling it, it had to be good and was probably made by Cascade the #1 selling dishwashing powder for them under their own label.
Over the years I noticed that there was what I thought was staining on the glass ware that I tended to use the most. Over a period of time it all became worse. I had throw away some of the dishes as they looked to terrible to serve wine or beer in or any other beverage. Even some expensive glass luncheon plates and glasses by Noritake were damaged beyond use.
I really became upset that so many things were ending up with this grey look on them; I decided to find a solution. This last February or March, I went to a restaurant supply firm to find out what was happening to my glassware. I was hoping to find out how I could remove what I thought were stains. I had tried using CLR and other products to remove the dull finish on my glassware, but nothing seemed to work.
When I showed the business owner, Wayne, the Tequila glass, he said, "that isn't a stain, you're glasses have been etched by the dishwashing powder you're using". He explained that some of the powders out there are very caustic and will actually etch glass, destroying their clean look. I was amazed, that something I thought was cleaning and protecting my glassware was actually destroying them.
When I took an inventory if what was damaged and what I had already thrown away, I was surprised. I went to Replacements, Inc. on the internet to find out the value of what was damaged or destroyed and was amazed. I had a loss of just over $600.00. I took photos of many of the items that I still had and went to Sam's Club and met with the manager. We printed to sets of prints, they kept one and I kept the other. They said they'd sent a set to the manufacturer which wasn't Cascade, it was a company called Huish Chemical in Salt Lake City. They manufacture products under the Sun Products name. I was told by the Sam's store manager that they would take care of the problem.
Well, after a few months I have gotten nothing except the run-a-round from Sam's Club, Huish Chemical and their two insurance companies. Their main reason for not paying the claim I presented them was that since I had known for so long, that since 2002, that I had a problem, that I should have stopped using their product. I advised them that I didn't know what was happening until this year. This damage doesn't happen after one or two washings, it takes months or even years for the problems to appear. It's a slow and insidious thing that you don't know what is happening until it is too late.
What is really interesting is the information and labeling on the packaging on the Members Mark dishwashing powder. It is a lie and misleading, plain and simple. They don't tell you that the product will etch your glassware nor do they tell you that it won't. There is no warning on their label that their product will destroy your glassware over time. They actually make the claim that their product is as good as or better than the leading product, which is Cascade, but it is not.
Their label reads as follows: Members Mark OUR PROMISE offering premium quality products at an exceptional value is our ongoing commitment to you. Independent testing guarantees that this and every Members Mark product meets or exceeds the quality and performance levels of the leading national brand. Your satisfaction is guaranteed every time you use this product.
Cascade has ShineShield, a buffering agent that prevents the etching of glass, Members Mark does not. The above statements by Members mark are a lie and misleading. Cascade is the nation's leading dishwashing powder, and Members Mark product does not even come close to having the protection that Cascade offers.
I have soft water...I use only Cascade..all glass is etched.
I would like someone with soft water to respond with an alternative to Cascade...an alternative that doesn't etch.
You all are wrong. We have tried cascade and have a box under the sink now. We have tried vinegar and different products and I just took some glassless out of the dishwasher and promptly threw some away. It seems that no one really knows why this is happening. We live in Tucson and at first I thought it was the Colorado river water
that is mixed with our ground water, but after reading so many posts it seems it is everywhere.
I live in Tucson as well, I've tried everything. A new water softener, less soap, more soap, different soaps, powder, liquid soaps, higher heat settings. Nothing works, I guess it's time for new glassware.
I live on well water that is softened by an industrial unit. I have only used Cascade Complete powder and my glasses are still etched. I now go to the dollar store approx. every 6-7 months for new glasses. My family members water is from Lake Michigan and there is no need for a softener although their water is harder then mine. They also use Cascade Complete and have no problem with etching at all. I personally think it has something to do with softened water.
And they also have the same rinse agent, I use to put vinegar in, which also worked great.
Cascade and Finish will not etch your glassware; but if you used some cheap dish washing powder (Like Sam's Club Brand in green packaging that looks like Cascade) for some time and then switched to either of the two above named products, they can end up etching. Once the glass ware has been etched by a cheap powder, the good brands can etch the glass ware, but they will never start it. See my photo at bottom of this article, the green plate. Soft water has nothing to do with it, as I've had soft water for 15 years and the damage I experienced only happened with Sam's Club garbage dish washing powder. By the way, when I used Finish for the first time I noticed an extra shine on everything as well, especially on the stainless flatware. Good stuff.
The only two I would recommend are Cascade or Finish. See note below. Also, you may have softened water, but if you air dry your glass ware or leave water in your glass evaporate out, the water can still leave a stain, which can be removed with something like CLEAR and sometimes very fine steel wool, like XXXX. It won't hurt the glass.
People are talking about two different problems, and they aren't sure which problem they are really experiencing. Water, itself won't etch normally. It will stain which can be removed with something like CLR and XXXX steel wool. If your water is etching glass, I sure wouldn't drink it. Think of what it's doing to your body! Only the caustic dish washing powders without buffers will etch glass. That stuff can kill you. Run some some tests to see what's causing the problem your experiencing and stop rhrowing away good glass ware.
Water softness varies greatly. The pH of Dishwashing powders are blended to work somewhere in the middle range of water softness/hardness. If your water is extra hard, then you will get scaling (calcium build up which can be reversed) because your powder/tablets are not acidic enough for your water. If your water is extra soft, then you will get etching (not reversible) because the powder/tablets are too acidic for your water. If you pre rinse your dishes then there is less work for the powder to do and therefore the water will be more acidic. If you don't pre rinse, then more of the powder will be "neutralised" attacking the grime resulting in less acidic water.
So, if you pre rinse, you'll need less powder than if you don't pre rinse (tablets may need to be cut). If your water is extra soft, you will need a less acidic powder. If your water is extra hard, you will need a more acidic powder. The solution would be for manufacturers to make a soft water powder and a hard water powder, but I don't know if any do. Another solution would be to blend your own with more, or less, citric acid.
In conclusion, the fault does not lie solely with the powder or the water but with the resultant combination of the two.
