Max Professional Contact Cleaner DPC 11oz is for sale.

Where packaging is applicable, the lowest-priced brand-new, unused, undamaged item in its original packaging.

I used the product on my radio and it cleaned up the volumn, but it didn’t clear the crackling on the knob, even though it did turn.It might be a good idea to use this product periodically over time to make it work better.The trigger button and straw are nice touches.

I am using this cleaner to get rid of the years of dirt on the contacts.The product has proven to be a great contact cleaner.I have used this product to restore one VTVM.I was taking apart the switches to clean them before using this cleaner.Allow it to soak and use it two to three times.

The only product I use to keep the switches working is this one.
