Surprisingly nothing happened to the lables. Nevertheless, I wouldn't recommend the dish washer method for vinyl that you really love (I did it only out of curiosity) - there are other, much better solutions.

My word...! How long did it take you to paste the labels back on the vinyls???

Other than the above, the OP is obviously trolling us... Some sort of odd Christmas-End Of Year tradition, perhaps.

This said, best of the coming silly season to you all!

This thread ought be automatically linked in all other threads that contain posts denigrating the practice of keeping a filter over one's lenses at all times. If Ralph's filters accumulate enough schmutz that he's considering putting them in an automatic dishwasher, imagine what would become of naked lenses.

Ralph, there's a clever little device you might try to avoid this issue. It's called "lens cap."

I guess he's a `mucky pup´ (Schmutzfink) - here's another thread ... https://www.photrio.com/forum/threads/lens-cleaning-solution.154701/

Originally dish washer detergent was pretty much the same as drain cleaner. Alkali hydroxide. After all the dishwasher has to do without scrubbing. Similar to an american car wash, where they don't dare using brushes. At pH 14 most food residues will hydrolise and come off easily. Imagine what that would do to your filter frame, unless it is stainless steel, chrome or gold coated.

Today its enzymes that do the job. I can't imagine that those would survive such harsh alkaline conditions, but I still wouldn't trust it.

Only speculation: I'm also not sure about the heat. Filterglass should be thin, which generally makes glass more restistant to cracking from large temperature changes. But expensive filters claim to be very plane. Maybe any tensions from heat would cause slight deformation. Especially with pol filters, which have many sandwhiched layers. Then, they might just come apart.

I definitely wouldn't do it. Dish washer detergent has some powerful enzymes in it that will destroy a certain materials. If you ever put polished aluminum into a dishwasher, you'll find out in one wash just how corrosive that stuff can be. Not only that, but the dish washer tends to thrash stuff around a good bit, which is why you're not supposed to put knives in it. Not to mention the rapid heating which can ruin wood. You might be able to figure out a way to make it work. But I wouldn't waste my time trying.

If you have a bunch of filthy filters to clean at once, I'd just fill the sink up with warm, soapy water (I use Dawn, dishwashing liquid), and let them soak for an hour or so. Then wash them off gently with your hands underwater, rinse them in warm water, and dry them with some microfiber cloths (let them air dry a bit on their own first, so your microfiber cloths don't get soaked right away). I did that once with about 200 filters that I bought from a guy for next to nothing, and turned around and sold them on eBay. Most came out in like new condition (despite all of them being disgusting before the wash), and I'm pretty sure the few that had scratches, had those scratches from before (I didn't sell those).

-) I do not seet a need for such

-) the typical cleaner compound is alkali- based and over time likely will corrode the glass suface haze, if not hampered by the coating.

I have a few "everyday" inexpensive mugs and glasses where the dishwasher has, over time, bleached the transfer colors from the mugs and made the glasses "frosted". Anything made of aluminium would also be quickly damaged by dishwashers.

my dishwasher scratches my drinking glasses over time. Not sure if it's the movement during the wash cycle, the detergent, or food partcles striking them. I would never think to wash my filters in the dishwasher. Why not do it by hand? I certainly wouldn't run a separate cycle just for my few filters. Seems like an awful waste of water.

A bit off-topic but NEVER put the print basket from a Patterson MAJOR model archival washer in a dishwasher, it will end in tears and be a mistake that will cost you hundreds of dollars to rectify.

I would not do it. If I tried I would use a water only wash. Dishwashing detergent will etch glass.
