Hi All,

I have a old off white keyboard that adore in
my shop.* The keys are starting to look a bit
nasty.

I have tried rubbing alcohol and vinegar and
nothing seems to clean it up.

Any words of wisdom.

Follow up:

As recommend by so many, I got me a bottle
of "cleaning ammonia" from wally world. I tried
a bit on my nasty looking space bar. Oh boy did
it look pretty afterwards! Worked like a charm.

But, the smell almost made my head spin. I will
take the keyboard OUTSIDE, probably over the
weekend, and finish off the rest of the keys.

Thank you all for the help!

Another advantage is that ammonia leaves no residue.

Get some silicone furniture polish and apply this to a rag and
wipe/polish the keys with it.

One of their ways to ensure 99.99% availability. Even after the
zombies attack you can still phone mom.

There's no way to ensure 100% availability, and not even 99.99%. It's
always possible for the phone line to be down.

As a matter of fact, in my experience, my cell phone has more
availability than my old POTS line ever had

In the UK the old Public Switched Telephone Network had service
agreements with that kind of availability baked in. That means when
you pick up the phone you get dial tone 99.99% of the time. Similar
requirements carry over to SLAs in the modern digital era. These
requirement weren't just to enable chat with your mom, but to allow
utilities to carry realtime info and instructions over the PSTN, now
over the Internet.

Ken probably objects to your use of "ensure", which implies a
guarantee. However, as Ken said, no-one can *ensure* availability, just
*strive* for that availability. And - as you imply - SLAs describe the
target for availability and what happens - often a penalty of some sort
- when that target is not achieved.

FYI, I was involved in 'Five Nines' - i.e. 99.999% [1] - 'HA' (High
Availability) computer systems.

[1] About 5 *minutes* unscheduled downtime per *year*.

Yes, use in a WELL ventilated area, I once took a breath out of a
bottle labelled paintÂ* thinners, Some asshole in our cleaning staff
had filled it with pure ammonia without relabeling it, Well I nearly
passed out and couldn't breath for a couple minutes, so be careful.

Oh no fooling!!!!





Yea, it was anhydrous ammonia, meant to be diluted for floor wax
stripping, powerful crap when pure.

Oh Lord!
