Cleaning with sodium percarbonate (1 Viewer)

[Colquhoun]

That last product is ridiculous. I’ll bet anything that adds “shine” AND “friction”...also makes it grab dirt faster.
Not on my chips, thanks.

CVS mineral oil for the win baby!!!!! Beats any of that for the finished product.

Can anyone find the ingredients for the "Clean Play" system? My searches have failed.

If it's composed of a buffered TSP solution containing sodium carbonate and sodium bicarbonate, there may be a patent infringement issue with "Diamond Chip Cleaner" whose ingredients are available on their patent application.

I'm pretty sure Diamond Chip Cleaner cannot patent the use of TSP, or similar, in cleaning chips.

They patented the components of the mixture, I believe, to use as a Casino Chip Cleaner. As per their patent application (and approval).

But they can't patent the use of a particular chemical. That isn't patentable. The only thing they can patent is their specific cocktail of chemicals with particular ratios. TDN wouldn't have to change much to dodge a patent infringement. Especially when TSP (or sodium metasilicate) is pretty much the only ingredient that matters.

Bumping a very old thread, but sodium percarbonate did a really good job of cleaning up stained sahara dunes $1s. Soaked for about 2~3 hours in warm water. Wish I'd gotten a good before pic, but there was some substantial browning that seems to be entirely gone. I'm actually a little surprised, I expected to go through a few soaking iterations. I would say there is some color fading, so using straight hydrogen peroxide may be a better method. Who knows though, after fully drying and either being oiled or getting some hand oil they may not be so pale. If used on a more valuable chip, I would definitely spot test with a small quantity first.

Strangely, the very worn hotstamps didn't show much change, but the few that had much fresher hotstamps were substantially eroded. So definitely don't use this on stamps.

I’ve looked at white Paulsons that had yellowed under a microscope. Interestingly, the clay is not yellowing…it’s the fibers (either cotton, nylon, etc) that get brown and make the entire chip look off-white.
Using Oxyclean is great at getting those fibers back to clear, making the entire chip appear less yellowed.

God, this level of chip degeneracy is something to aspire to be.

Makes me so doggone proud!

Does oiling chips cause the edges of the inlays to soak it up and become discolored?

Haven’t found this to be the case

 

[AlbinoDragon]

But it can, particularly shaped inlays. I have Empress $500s that started to show oil creep after an aggressive oiling and my PCA$100s do for sure.

Trickier than I thought. Quick and dirty. Microscope camera not working, so phone camera on the eyepiece.

Burt Co jockey mold illegal. Hint of fibres on edge.

Mint CPC.

 

[Colquhoun]

Here’s an example that I found. Chip looked a bit dingy, not bright white. Under the microscope, the chip color was white, but all the fibers were light tan.

Weird. Lots of fibres on face. Cotton that is yellowing perhaps.

Yeah, theres always lots of fibers on the edge, but plenty right on the surface of the chips as well

For science, apply treatment for fixing yellowing cotton clothes?

 

[Colquhoun]

I'm not sure cotton is used anymore...from the looks of it, the fibers are some type of... *gasp*...plastic.

Shrug, go find a treatment for yellowing plastic then. Good luck.

Yep, and inlay discoloration can also occur from cleaning solution seeping underneath inlays, particularly shaped or older Paulson inlays or ASM/CPC inlays which are not as securely adhered. Dirty solution can permanently stain paper or linen inlays.

People have had good results soaking in hydrogen peroxide under UV llight. The process is commlonly used in restoration of yellowed or aged computer cases.and similar products.

Shoot! Now I don’t know if I should oil my CPC chips when I get them. I spent a small fortune and sure as heck don’t want to mess them up.

Oil your CPC's, but only the edges. There's no need to oil the faces. I don't know why that is, but every ASM or CPC chip I've ordered (16k now) hasn't seen a noticeable improvement from oiling the faces.

You also don't need that much oil. I'm sure there are people here who will protest, but I can oil a thousand chips with no more than a tablespoon of oil.

I'm still on my first bottle of oil which was probably bought 15 years ago.

I think the reason is that the fibers “lay down” on the faces under compression, and mix in with the other materials. However, with the grinding (or lathing) phase, the fibers are trimmed and they stick out on the corners and straight out on the rolling edge…almost like a 5-o’clock shadow beard. That’s why rolling edges often look fuzzy and off-color…and why a touch of oil brings the color back.

Absolutely what I'm seeing too.
Fibres would take up oil if the were absorbent...
... like cotton rather than plastic (ducks and runs).

Looking at the fibers, they just don’t look like a natural material…they look like nylon or polyester. Nylon can still be absorbent, and it cooks also be that oil is slightly absorbed into the voids between the fibers and other materials.
I also think that part of what makes the colors pop is that the oil is scattering the light…similar to how Armor-All makes a plastic dashboard look new without actually soaking in.

I've been a botanist for over 15 years, spent a lot of time looking at plants down a microscope. Plants are covered in all sorts of hairs. These ones in our chips don't look unnatural to me. But I can appreciate that is informed opinion and not proof.

It’s neither informed or proof. Just opinion.

 

[drdr]

Odd response. I even stated is an opinion. I'd take opinion from anyone with over a decade of experience as more informed than those with none. Otherwise I may as well ignore my car mechanics opinions on the need for motor oil (for example). Shrug. Regardless, I'm actually interested in finding out for sure rather than just saying "I'm right". As a scientist I have no problem finding out a hypothesis is wrong. Would be pretty simple test to take a sample of hairs and see if they melt. Huh, I reckon I'll try this.

Lol, all I meant was that I thought the fibers looked like plastic. It’s not an informed opinion, and I have no proof. I didn’t say “I’m right”, and frankly my interest of what they really are is pretty low.
I’ll leave that to you scientists.
