Cleaning Question

Is there anything out there that will clean PVC damage from early copper coins without damaging the coin? If so how does one apply it for best results?
A good friends family found out that I collect. They brought a few inherited coins by for me to look at. Nothing of super value (mostly very warn silver) but there were some very nice early colonial copper coins. Unfortunately they have been kept in PVC flips for the last decade. I would like to send them to PCGS for grading if I could only get the slime off. Any serious advice would be appreciated.

how bad is this damage?
mineral oil soaking for extended periods produces safe results but surface damage is surface damage
can you post pictures?
<< <i>you may consider posting images as pvc damage can equal body bags

I would but I dont have them in hand. They dont trust me that much
<< <i>so pass advice to them to at least get them soaking in mineral oil for preservation sake >>
Please educate me. How long does one soak? Once soaking is complete do you rinse clean or just let air dry?
i've soaked for 3 months with camel hair brushing the copper every 2 weeks in it's soaking and was happy
keep in mind this damage took years to occur so don't be in a rush to conserve it overnite
