Stains on my tubes removal

[mctaggart]

Hi

I have got my rib out from its winter slumber yesterday and started to do some work on her for spring. I have noticed that I seem to have picked up stains on my tubes from my cover, it looks like some kind of mould by the way its patchy.

I have used my usual tube cleaner product, sprayed on and left for 5 minutes and started rubbing hard and although it took all the crap off the tubes and made all my rags the same colour as my tubes bright orange! It wouldn't shift these stains.

Has anyone else had this problem and if so what should I use to remove it, pictures attached.







I have tried using a brillo pad and the same chemical to clean it up and although it seems to be removing lots of orange from my tubes (which I assume it the top layer) its not moving!

I have got some acetone I am thinking of using on a rag, will that be ok my tubes?

Try a bathroom mould remover.

ill let you know how I get on

It's on the inside coming through and caused by the moisture in the air inside. You won't clean it off easily or at least not without wiping away your hypalon as well.

Ah your joking, how am I supposed to treat that?

I've had a theory, but I haven't had a chance to test it.

Splash a commercial grade ammonium chloride mold killer / inhibitor through the valve...maybe about 1 liters worth? Leave it in the tube and drive around with it that way. After a good amount of splashing to entire the entire inside is coated, top and bottom, remove the valve and vac the excess out.

I have not tested this yet for negative interactions with glue, mastic, or the lamination of the material.

The exterior can be treated with a hydrogen peroxide based mold removal solution / whitner. If further whitening is required, I like a mildly abrasive bleach gel. Be sure to treat with 303 Protectant afterwords.

Although I could be mistaken my guess is that there is a strong possibility that this is surface attack (caused by lack of ventilation) and not attack from the inside, so worth a try to remove accordingly.
- not our material though !
Good luck

try H G mould remover

I might be mistaken, but that looks as though it is caused by your cover. If your cover is PVC, the "sweating" of the cover releases plasticisers in the PVC coating of the cover and they will migrate into the surface of the tube fabric. That is one of the problems associated with the cheaper PVC fabric used.

I'd be very wary of a Brillo pad too.

Angle grinder will probably get rid if it aswell! 😜

Cillit bang black moulf remover is the best I've found. I did a thread about cleaning tubes last year or the year before and cillit bang came out on top for mould removal

Hi mctaggart
Any luck with removing those stains yet.
I have same problem. I always put my boat away dry, including the cover, but as the stains are only on the port side tube, it could suggest moisture inside. Thing is I don't like the idea of putting anything in the tubes except air.
Have tried all products mentioned with no luck so far.
