Simple Green has always been listed as a food safe cleaner. But as I
recall it's also supposed to be used diluted. I've cleaned all sorts of
surfaces with it, both diluted and full strength (for the really nasty
stuff) and never had a problem with it. I also rinse the surface
afterward.

That said, there's also a Simple Green that's an industrial cleaner that's
not food safe and is also supposed to be used diluted. I use that for
cleaning machinery. They even recommend you wear gloves when you use
that. As with the regular SG, I always rinse afterward. You'll find this
stuff with the power wash cleaners at places like Home Depot, Lowes, etc.

I took a look at the bottle of SG that I have (again, from the automotive
world as a degreaser) and the bottle looks intact. Actually over the
years of heating cooling cycles it has leaked some out the spray head and
dripped down over the bottle, making it look like the bottle has leaked.
After drying cycles and combination with dust, it leaves a nasty mess over
the bottle (I don't use it often, haven't had to do much car degreasing
lately.)

I never thought of using it for surfaces used for food preparation before
but now it seems I definitely should avoid doing so.

To me cleaning is a balance of taking off just enough but not too much. I
have used the simple green on a lot of stuff, it is power full and if too
concentrated for too long it will take off some of the paint on the
engraving of a 500 series for example, but at the same time I think it takes
off the smoke tar and salts that is corroding aluminum from the scopes that
I have found here near the coast well, so there is already a fair amount of
corrosion. The amount of power can be controlled by the dilution 10:1 to
1:1. I do wash quickly, with hot water spray wand and rinse very well and
then blow everything with a leaf blower to remove any excess water (vs
drying which leaves anything in the water on the surface. If it's something
important I rinse it three times and then with distilled water using a water
pick, if it's really really important I "triple rinse and blow" (which less
the blowing is required to be use to clean pesticide containers), Done a lot
of pcbs etc.

I do enough cleaning that I got some Liquinox is from McMaster Car I am
going to give a try.

Also
Simple Green Extreme, sold for airplanes that you don't want to corrode is
about $20 a bottle vs $10 for the regular and I was looking to try that too,
like to find a local source. Which I might tend to use on things with
laminated metals in the future.

Re: Simple Green

Good enough reason not to use it! If you can't easily define what "it" is, then you could end up with the wrong thing. I checked as Dave suggested, by googling MSDSs and

http://www.uline.com/PDF/MS-11732.pdf...has a health hazard listing of 0 (!!!), but

https://www.conncoll.edu/media/website-media/offices/ehs/envhealthdocs/simplegreen.pdf...has a hazard listing of 1, and

http://www1.mscdirect.com/MSDS/MSDS00023/62280987-20151122.PDF
has a hazard listing of 2! All "simple green". Not so simple apparently.

Maybe I should not have used it on the BBQ after all, but I power washed the grill afterwards, then ran it 15-30 minutes to bake it out, and wiped down the grills with olive oil, so pretty sure there are no residues left behind. Nothing I can smell anyway.

I think I will stick to using it for cleaning mechanical items and car parts in the future. Note faceplates.

Safe to cook on that grill after using SG on it?

Subject: Re: [TekScopes] Simple Green

I used Simple Green on a very grungy scope cart last year, just before all
the discussion here about it.  The cart came out ok, fortunately.  And I
power washed it.
But just this weekend I used it on a filthy BBQ grill - it worked well for
that, but it softened and partially removed some of the cheap chinese black
paint on the shelves of the unit.  I've never had a cleaner grill, but I
would not use the stuff on instruments for fear that it might begin to
attack the paint.   I think part of the reason it removed the black paint
from the grill may be that those surfaces were exposed more to UV, hence
already had weak paint.  So, even robust instrument paint may become more
vulnerable over time.

I believe they changed the formula some time ago so your old bottle
may have held something more potent. Interesting story.

I recall in the past comments regarding use of the cleaner product Simple
Green to help in restoration of legacy test equipment. I myself has not

regarding certain characteristics that I was surprised to discover.



A few years back I inherited a gallon jug of Simple Green. Not really
having a planned application for it, I placed it in the basement storage
room. A few months back I noticed that the container had apparently sprung
a leak. Examining the bottom of the plastic jug, it appeared that the
product had started to leak out through a small seam that is created where
the halves of the manufacturing mold mate with each other.



As a quick “fix” until I could transfer the cleaner to another container, I
placed it in the fiberglass sink in the laundry room. Over time a small
portion of the cleaner leaked out from the jug and down the drain. I
thought it was safe being there until I could take action in transferring
the contents.



But I was wrong.



Today as I passed by the sink, I noticed a wet spot on the floor beneath
the sink. It was Simple Green. The product had eaten through the metal
drain trap beneath the sink. But it didn’t stop there. Lifting the jug out
of the sink, I found that it had also started to delaminate the fiberglass
layers in the sink bottom as well and had started significant corrosion of
the metal drain. Closer inspection of the bottom of the plastic jug
revealed that the product was actually dissolving the plastic of the
container.



The Simple Green was immediately disposed of.



If one uses this product for cleaning sensitive test equipment, I would
advise to use very weak concentrations and thoroughly wash the item off
after use. I would hesitate to use it on various plated items unless the
effects are well known as well as allowing it to come in contact with
those items which may allow the solution to be absorbed or trapped within
them.

Re: Simple Green

 

I'd have to believe someone added or put something else into that bottle. I
used Simple Green for years, until I discovered "Awesome" cleaner, and
never encountered anything like what you described. Simple Green is a great
cleanser, great on greasy auto parts and even used by gunsmiths for
cleaning guns (that's how I heard about it). But I've never before heard
anyone mention any deleterious comments such as you describe.

Guess my plumbing was one of the things that they intentionally left out.

Didn't try it on an aluminum surface. Might have been a good pre-treatment
to allow the primer to get a good "bite" when painting it.

Re: Simple Green

Managed to retrieve the bottle to check the formulation. Unfortunately there was no listing of the ingredients although they stated that it was "septic safe" is "safe for cleaning everything" and "environmentally friendly."

Guess my plumbing was one of the things that they intentionally left out.

One other note - when I wiped the residual leaked cleaner off of the concrete floor, I discovered that it had etched the concrete leaving a rough pitted surface. Now that's a cleaner!!!

Didn't try it on an aluminum surface. Might have been a good pre-treatment to allow the primer to get a good "bite" when painting it.

Re: Tek generic parts cross-reference

 

It is funny you should mention that. One of my PS-503As has 301
operational amplifiers in place of the 741 operational amplifiers.

As far as performance and characteristics, they are practically
identical in this application but the 301 requires external
compensation in the form of one capacitor and these were added to the
back of the board.

With some component changes, the performance of the PS-503A could be
improved quite a bit but it already works great as a power supply.

I guess we need parallel processing scopes down the road, like when PC RAM went to DDRx speeds.
I think you mean pipelined instead of parallel processing but it is
not much help with this. There is nothing to prevent a new aquisition
cycle while the processor is processing the old one but this only
doubles performance and to work best, it has to sacrifice at least
half of the record length to make a ping-pong buffer in the aquisition
memory.

The DPO method is to have the aquisition hardware process the data as
it comes in to produce a histogram in the aquisition memory. This
works very well and FPGAs are well suited to this.

Re: Tek TDS694C advice pls

 

It is consistent with the numbers I have heard discussed. High
performance logic (CPUs, FPGAs, whatever) is designed with an
operating life of 10 to 20 years in mind at about a junction
temperature of 65C. This falls apart with consumer stuff like from
nVidia where performance is gained by operating at high temperatures
lowering operating life to the minimum. You do not find a lot of old
high performance graphics cards compared to CPUs.

As for lifetime vs temperature, the anecdote follows the factor 2 per 10C. The name Arrhenius comes to mind.


Re: Tek generic parts cross-reference

 

Tektronix Semiconductors Common Parts Design Catalog is available
online as a PDF file and translates between Tektronix part numbers and
manufacturer's part numbers. It also lists important specifications
for the parts making it relatively easy to find modern replacements.

When working from the specifications to find a replacement part
however, some technical knowledge is still needed.

Occationally someone makes a replacement parts list available for
specific instruments however I have never seen one for the PS-503.

Re: Tek TDS694C advice pls

 

In this case performance is limited by the CCD. In theory the CCD
could be segmented in place of memory but I do not know of any cases
where this was done and there would be a limit to the time between the
first and last segment because the samples in the CCD degrade
relatively quickly where with RAM they do not degrade at all.

In these instruments with their relatively small memories, no memory segmentation and large acquisition gaps, successful acquisition of the signal of interest often depends on advanced triggering possibilities.
OTOH, I intend to use my '694C connected to my TLA710 Logic Analyser (Cross Trigger), so in terms of logic triggering, nothing fancy need be contained in the 'scope.

The trigger chips are TQFPs. They have heat sink pad underneath, much like a QFN.
Rather tedious to replace.
