Interesting Discussion Surface Cleanliness Real Time Test Tools

For years we have used a visual method when determining if the metal we are cleaning is "clean". After some customer complaints I'm looking for a more robust method. Beyond the SITA CleanoSpector and the WA Clean Tool (which beyond mention, I can't find much more information) does the group know of any other real time test tools out there?

I'd rather not rely on one companies technology if I can help it.

Thanks in advance for your help.

It has to be clean enough for paint to adhere to it. We have a visual limit, per the rags we use, but I'd like to get a piece of equipment so I can develop a variable limit. While at or near zero would be great, I know from a video of one of the units ==>

that a thumb print will read 26.7 RFU's or whatever unit this equipment displays in. I know our paint will still stick to thumb print oils, so zero might not be an appropriate limit.
