Tube cleaning

Hello there, what advice have you for cleaning pvc tubes, they have been described as oxidized? In the past I have used pro marine cleaner and a scouring sponge.

Don't know about PVC restoration solvents or cleaners but you shouldn't be using a normal scouring pad on tubes, especially with solvents or cleaners. You can get specialised pads for the job that are reusable for a few quid from rib places.

Give Ross at ribstore a bell, they were excellent helping me getting rid of some stains on mine and recommended some products they knew worked. Wasn't a sales pitch either btw!

Soaking wet cloth with acetone. Dissolves the oxidized layer. Wipe it clean.
Looks like it came from the factory. But itís now completely open in the structure.
I spraycoated my PVC with a flexible lacquer.

Be very careful using strong solvents, acetone, MEK etc. If you're not careful you can "weld" the grime into the material itself. Think tattoo

The secret is to use plenty, if you allow it to dry dirty it's a bugger to get off.

Tube cleaning

It needs to be soaking wet, wet as being a mayor mess down your arms, boots and all over the lawn.
If youíre bankrupt as I am, itís worth the time, but daaamn it took three guys a solid weekend to clean. Me another week to coat. And if one is smart, those hours could probably be used to earn the money, to just go and buy a freaking brand new tube...

Remember if you are using solvents such as Mek or acetone you are breaking down the PVC material and will shorten the lifespan of the boat. Makes it look good, but you are removing a layer of the tube material itself.

Personally I wouldn't use solvents just to clean. I've been there. Especially if the boat is older, and the tubes are worn some, you'll start running into problems in the near future.

Buy for 100$ of "special RIB clean" and pretend it isn't oxidized. I take you can figure out, it won't fix your problem. But kinda looks like it does. At least for a week or so.

You have two.. well three choices:

-Let it rot on, it WILL crack soon. The PVC has become brittle by the UV breakdown.

-Give it acetone, it WILL start to leak soon. But it has now regained it's elasticity.

-Give it acetone, then right away, when still being sticky, treat it with a flexible polyurethane compound, it regains it's original vivid color, smooth as glass and it becomes way more durable than a new hyperlon tube.
