Use of Copper Fittings

[Waqas Ahmad]

Hi,
I am working in an Ac Assembling Factory. We developed the copper fittings from our vendor by giving our copper tubing.But he did not care the fittings and kept them in an open atmosphere without any wrapping at least 7-8 months. Now we want to use them but these are very dusty and might be dust travelled inside th piping as well. We are afraid of Complaints from After Market. Kindly advise because Copper is very expensive. Should we use these fittings? If yes, kindly advise the cl;eaning process.

Regards,

Can we use some chemical for cleaning copper fittings like CTC (Carbon Tetra Chloride)
