منظف جهاز NES - خرطوشة تنظيف نينتندو من 1UPcard™

Finally got my old NES working again after just one pass with this cleaning cartridge—the 72-pin connector was visibly grimy. The whole process was way easier than taking the console apart, and now games load on the first try without any gray screens.

My NES was constantly showing gray screens no matter how many times I blew into the carts. One pass with this cleaning cartridge and the 72-pin connector feels fresh, and the picture is finally stable. Best ten minutes I've spent on my console in years.

Finally getting a stable picture on games that used to give me the blinking red light every time, all it took was a few inserts with this cleaning cartridge. The 72-pin connector must have been pretty grimy, but this thing cleared it right up. Well worth it for saving my old console.
