Tony, is the mould on the outside of the silicone, or underneath ?

If on the outside, have you tried a weak solution of White King or similar bleach ?
Maybe water down 10 water to 1 bleach to try, use an old tooth brush or stiff old paintbrush.

Silicone is pretty resistant to almost all checmicals I can think of, nothing removes it afaik.

And if the mold is underneath the silicone then you have a real problem.

Mold generally means there is an underlying problem with mold spores trapped in a moist environment through poor manufacturing standards.

If the mold is under the silicone simply stripping out the silicone and reapplying will simply be a temporary fix.

hi bronty
if its on the outside use truck-wash CT18 from supercheap and a stiff brush
i have successfully used this method on my old van after it sat through winter and spring and grew mould on 3 different occasions but if its underneath the silicon surface then its as said above al-cheapo silicon has been used and it needs to be all stripped off and resealed with quality sikaflex silicon
there's far too many caravans been built these days with al-cheapo methods that's why so many of them leak water and if the joints been sealed are not free of dust before the silicon is aplied then it doesn't adhere properly to the joint in the first place and will leak and start mould and allow water intrusion
the caravan industry doesn't have very little quality control and companies rely on there staff to do the right thing but there is huge amount of evidence that this doesn't always happen there are plenty of horror stories of buyers of new vans experiencing water damage after there first trip away
I hope yours isn't one of them

G'day Bronty

Every now and then I have had mould on our awning and pop top.

I find cleaning vinegar easy to use. Just spray it on and use a soft bristle brush, then wipe off and bobs your uncle.

Oh, leave the vinegar for about 1 minute or so before the brushing.
