Questions PCB electric contacts gold of the sd2snes

The sd2snes PCB has gold contacts, how many inserts and removed from the cartridge to scrape off remove the golden layer contacts?

This is a very good question, because it depends on many factors.
- In which way are they produced, there are different options available:

- "With the correct thickness and application, gold fingers can be used reliably for close to 1,000 cycles before repair is required."

- How clean is your SNES connector? Dust etc. may reduce the lifespan.

I want to keep my SNES as good as possible, this is one point why I bought the classic SD2SNES years ago. I keep it always in, so I only need to work with the SD card slot. If this slot breaks one day it can easy be replaced :)
And today, nearly all SNES games work and also the SuperGameboy seems to work, there is no need to take the SD2SNES out any more :D

Nevertheless, there are products out to protect gold contacts. I personally use Kontakt GOLD 2000 for my PC cards and consoles since years.

Hope this information will help you :)

You can store them in those kitchen plastic containers, making sure the air inside is dry when you put the cartridge.

I don't have these plastic containers I keep in closed cardboard boxes and inside these boxes the cartridge inside a semi-open anti-static bag

What about buying silica gel bags or plastic containers?

I put 3 sachets of silica gel inside a shoe box but it is not airtight and inside the box contains the semi-open anti-static bag with the cartridge inside it

Maybe we should ask first what do you understand as "moisture".

As long as you keep PCBs in your room you will not have any moisture problems.
In the basement it may look different. But how do you store your SNES, your TV,...?  These device may also suffer the same way from moisture.

Nevertheless... on eBay you can find metal ammo boxes which are waterproof. I have seen a foto somewhere in the web where the SNES cards perfectly fit into that. There are different sizes of the ammo boxes.
You also get Silikagel on eBay, but make sure not to buy "blue/orange silica gel" as it is known to be toxic.
"... Cobalt (II) chloride is deep blue when dry and pink when wet, but it is toxic and carcinogenic, and was reclassified by the European Union in July 2000 as a toxic material. ..."

Hi, I store the cartridges, and other electronics, wrap them in transparent pvc film, those for storing food in the refrigerator, if the day is too humid I use a room dehumidifier, I even used a hair dryer to decrease the humidity, hurry...
