Degreasing PVC tubes

Looking to apply some vinyl lettering to my Zodiac which will require degreasing the PVC tubes.

Any recommendation for suitable household degreasers? I may have something already or can pick something up from the local shops and not have to order a specialist product in. Have already washed the tubes with water and mild fairy liquid.

I did a quick search and acetone was mentioned. What about meths or white spirit?

White spirit will leave it greasy. Meths will work.

Did a load of repairs to an old pvc narwhal a year or two back that my daughter and her fella had got stitched up with , and acetone is a must for glue to work , it opens the pores in the pvc somehow and allows the adhesive to get a proper key . The instuctions on the glue were adamant about hard rubbing with acetone a number of times before actually gluing , the patches held really well once i did it by the book .
meths is ok for normal de greasing but not for glueing .

As I understand it, MEK is basically the liquid modelling glue. Have you seen what this stuff does to plastic? I use to melt old sprues in it and create liquid plastic filler.

Meths it is. It was recommended by the boat graphics company but the instructions were not specific to PVC tubes and carried a disclaimer to check suitability of any degreasant used on inflatable tubes so needed to double check its suitability on PVC.

Why would white spirit leave it greasy as its used as a degreasant for many things?

White spirit is actually a slightly greasy solvent.

Are the letters like van graphics ie self adhesive like stickers I thought you were using letters made from the same pvc as the boat and need to use pvc glue ?

I don't know exactly what the lettering is, but they are self adhesive like van graphics but much more flexible material for use on inflatable tubes that will be left mostly deflated - I had to specify this when ordering and discussed the options with graphics company who are specialists in marine and aviation graphics.

I'll be surpised if they stay on for more than a few deflation - rollups
