Dehumidifier on a rib good or bad idea?

[lifeboatman3]

Just wondering if leaving a dehumidifier running on a rib is a good idea? I put one on this year as last winter my rib was covered in black spots. Its kept outside with a full cover. I was talking to someone and they said a dehumidifier might not be a good idea and dry out the tubes? Any thoughts

I don't think it's a bad idea if using an energy efficient desiccant dehumidifier, certainly won't do any harm.

The black spots are the same mould that is difficult to remove on my Indian sandstone patio. Best approach here is to use a sealant so it can't get a grip and I think the same could be done with your tubes.

Ceramic sealants using SiO2 technology are extremely hydrophobic and work on glass and rubber like they do on car paint. Might take a bit of removing for a patch repair but sandpaper should take care of that. I could be wrong but think the 303 protectant folk here use on their tubes is similar stuff.

I just use an oil filled radiator in my boat. Keeps it a bit warmer than ambient and therefore stops all condensation. It’s not just the black spots, but all your wiring and other fittings - none of it likes to be left damp for months on end.

I use a couple of these in the caravan when it's in storage :-

Saw them in Tesco for £6

Damprid is a moisture absorbent brand over here. It comes in a nice container with a tray on top on top in a bucket to catch the water. I bought a few and refill with calcium chloride from the hardware. It doesn't absorb below zero temps but when it warms up the buckets fill with water in the spring. The refill is inexpensive and no need for electricity. They don't cover huge areas so you may need a few.

Has anyone spilt the collected liquid? I did this once in a caravan and it was impossible to dry the carpet out despite much blotting, it was greasy. Reckon the damp patch would then have collected dirt. Wierd stuff. Not a fan now.

I buy the larger damprid containers which are probably 4 liters or so and they will only fill to about 1/4 with water. They contain the liquid quite well. The smaller containers are a pain and I can see a spill.
I can see being mad about it. It's the same stuff we used to fill large tractor tires for weight. Mixed with water so it doesn't freeze. We had a special machine to do the filling and if you spilled any on your boots that was the end of them. Dried them right up and destroyed the leather. Strong stuff but it works if contained.
