anytime i got alcohol on abs type plastic it turned horribly white. which is intresting because metadot states to "clean your keyboard with a drop of alcohol". maybe the das is some other type of plastic. it sure looks to me if it were applied to the shiny case it would mar or turn white. i don't plan on trying it.

which brings me to ask a question: is metadots customer service as terrific as zf/cherry? i am guessing metadot would give someone a hard time about a warranty return. just a guess. on the other hand zf stands behind their products 100%. different market, they have to. these are serious business machines that are the backbone of fortune 500 companies. i am also guessing the das will not break in a year. i am going to ask metadot for a small favor monday. i hope they oblige. i'll let you guys guess what i want from them lol.

Their customer support service has a very good reputation... Especially in regards to returns when they were selling keyboards that were unusable

I'm still curious what cause the damage to the keys in your pic.

Interesting, an AT102DW didn't seem to mind (but the glue remains came off nicely). I haven't noticed any adverse effects with typical Cherry ABS/SB cases either. Now of course (a) these typically are beige and (b) I don't drown the cases with alcohol but rather wipe them with a wettened piece of toilet paper (same as for used CD jewelcases - if you ever get one that's suspiciously dull, you may be surprised at the brown stuff coming off...). 94% denatured spirit btw.

(Did you know that the substances used for denaturing tend to be used as softeners as well?)

Hm that kind of submarines the idea of doing acetone + RIT dye like the yo-yo dying dudes.

It looks as if he used acetone, and I think I remember him saying he used it too.
=)

Edit: Ooops! I forgot to refresh, rippy beat me to it!
The acetone and dye works pretty good, just check to see if the keys are coated. In general you just need to be more cautious and wait for the plastic to harden afterwards. As a tip- it can greatly help the dye consitency in the part if you lightly break up the surface tension in the water based dye solution.

metadot states "if the keys or case become soiled, use a small amount of alcohol to clean them".

i did this to an adesso and had the same results as the op in this thread.
i do not see how the das is different since it uses the same materials.
i will just go ahead and do it to the das. if the board or keys are damaged i will take it up with metadot. i suppose filco does not make a similar statement to that of metadot. unless the das is in fact actually something other than abs. you do not contact alcohol with abs plastic for good results afaik.

There should be nothing wrong with that.
I have cleaned hundreds of keyboards with alcohol with great results, not once did it cause damage. In my tests earlier in this thread I had even shown how cleaning with alcohol is ok. It's letting it sit in alcohol that is "sometimes less desireable" with "some coated" keys.

If anyone is really worried just do a test spot on the underside or back of one key.

lol, ripster.

i used a cotton swab soaked in alcohol 91% to clean an adesso's keys. they turned all cloudy white. maybe that was just a fluke. i did seem to remember that alcohol will melt abs plastic. that is probably after prolonged contact though. i imagine if you just wipe it and dry it is is good. i do not know what happened to that adesso. it looked like the op's in less than 30 seconds of contact. it could have been a wrong formulation on some run they had. i have no idea, just guessing.
