Hello, I recently bought my first pinball, a Stern TWD Pro.
It needs a cleaning and I've read the long thread here and watched several YouTube videos and wanted to make sure the steps and supplies I have down are correct before I completely this thing and make a dirty problem a future repair job. Apologies in advance for being the noob. I'm still learning.
Vacuum With Brush Attachment
Step 1: Use a vacuum with a brush attachment to pickup any loose dirt or dust that's on the playfield.
Step 2: Put a very small amount of NAPTHA (not sure which to buy though?) on a microfiber towel and apply in circular motion to remove buildup on playfield.
Step 3: Put a very small amount of NOVUS 2 on a microfiber towel and apply in circular motion on playfield.
NAPTHA - I'm not sure which to buy AND I have kids as young as 6. The pinball is in one end of our living area. I've read this stuff is pretty strong. Does it go away quickly? Say I apply it to the microfiber outside and then walk inside with it to keep the bottle outside (less fumes maybe?) Is there an alternative that would be safer by chance? I've read a lot of people use NOVUS 1 or even non ammonia glass cleaner for Step 1. Better/Worse than NAPTHA?
NOVUS 2 - I've read a lot of caution on using this since it's abrasive. If the NAPTHA is to clean the machine what purpose does this have? It's not a wax so what the heck is it actually doing?
