Thanks for the interesting comments..
Cantex makes a solvent/cement combo.
I called them and they said they recommend using a chemical cleaner prior to using cement.
When you look at the installation instructions for the conduit there is no mention except for solvent...
Kinda confusing..
I think the NEC should have a section regarding the installation of PVC etc and cleaning...we all know it will not hold if you just wipe it off or if it is wet/muddy...it will pull apart exposed or underground with freezing water inside...
thanks
