Neosporin…the Retrobright for bench equipment?

polishing-knobs

[linux-works] picked up an old power supply from eBay, and as it was built back in the 60’s or 70’s, it was in need of a little TLC. One thing that immediately caught his eye was the condition of the knobs, dials, and banana plug receptacles – they were dull and faded, showing off 40+ years of heavy usage.

He started off by simply removing the knobs from the power supply, giving them a thorough cleaning with soapy water before leaving them to air dry. They didn’t look any better afterward, so he decided to take a different approach and apply some triple antibiotic ointment to the knobs. As it turns out, letting the ointment sit for a few minutes then wiping the knobs with a soft cloth really made them shine, as you can see in the image above. [linux-works] attributes the effect to the white petrolatum base of the product rather than the antibiotics, likely making a wide array of products equally suitable for the job.

We know how well Retr0bright has worked for the vintage computer folks, so we’ll be interested to see how long the effects of the triple antibiotic treatment last. It certainly can’t hurt those readers who spend their time perusing flea markets in search of classic electronic equipment.
