“Jack…come on in now. ”
“OK I just finish sniffing this bunch of grass.”
“Hurry up then it’s raining now.”
“Oh wait, here’s a brick, gotta sniff it. ”
“It’s a brick, there’s nothing to smell on a brick.”
“Hahaha! You humans…you know nothing!”
We invest a lot of money in our vans and most of us keep them for a very long time. For this reason maintenance and repair is important to ensure things last as long as they can and operate as they should.
One thing that should be done at least every second winter is checking and caring for your rubber window seals. They are very large and have to put up with detergents, polishes and other chemicals on the inside, and road dirt, washing chemicals, harsh sunlight and freezing on the outside. In addition with the window closed the rubber is lightly compressed for very long periods of time. All of this takes it’s toll on the rubber so a maintenance routine is important and mine is very simple.
Firstly I wash the rubber seals with nothing but warm water and a microfibre cloth. I make sure I give them a good rub to ensure any surface dirt is gone. Then a rub with a dry cloth to encourage drying.
Then I use Castrol’s Red Rubber Grease and rub it in as if I was rubbing an ointment into skin. I almost massage the rubber to ensure the grease is worked into it as best I can. It takes very little grease to achieve this and it’s not too expensive anyway.
I use latex gloves simply to prevent myself getting all oily and once all of the rubber is done, I leave it for an hour or so to ‘dry off’ before closing the windows.
I did have a leak in two windows some time ago which was what started me off researching how to look after rubber. During very heavy rain I found the water would somehow seep through between rubber and window and pool on the inside. It even pooled so much one time in the bathroom that it leaked over the edge and ran down the wall. Since greasing the rubbers though it has never happened again.
Many people say use Petroleum jelly but I’ve also read that you should not use any petroleum based product on natural rubber. I’ve also seen photos of rubber that was allegedly destroyed by using WD40 on it. On one forum a bloke told how he’d used KY jelly to lube his rubber products but as he never stated what products they were…I ignored his advice! Some say petroleum jelly dissolves latex, which is a form of rubber.
I’ve no idea of the veracity of these claims but as mentioned, the grease I use is Castrol Red Rubber Grease. Castrol red rubber grease is made essentially from vegetable oil, and certainly olive oil is claimed to be the closest product to the oils in natural rubber but any vegetable or plant based oil is considered safe or “rubber friendly” as rubber is actually a product direct from a plant.
I think the compatibility of red rubber grease is based on its properties for use in braking and hydraulic systems where it works well but does not interfere with braking and hydraulic fluids, as some greases do.
The primary purpose of red rubber grease is preserving natural rubber parts but here are a list of properties I found on this web site:
So you can see it passes way more tests than it needs to to protect your window rubbers and it’s not prohibitively expensive at around £11 per half a kilo. I’ve been using it every other year now for about 6 years and judging by how much I’ve used I’d say it will last my lifetime easily.
Interestingly, it is red because it is dyed so as to differentiate it from other grease during manufacture. And I thought at first it was just a cool and trendy name…
Condensation is a matter of fact, it’s part of life, it’s physics and as Scotty will always tell you, ‘You cannae change the laws of physics!”
So what is it? Simply put it’s when a gas turns to a liquid. The gas is warm air, the catalyst is a cold window, the result is gas turning to liquid ie: water. The warmer the air the more humid it is, the more water it contains, therefore the more condensation when the warm air and cold surface meet. The opposite of condensation is vapourisation, when a liquid turns to a gas. ie: water to humid air.
Condensation in a motorhome is of course unwanted as damp over time can lead to mould and can even affect the structural integrity of the wood frames inside, rot fabric and corrode metals. To try to minimise this happening the air humidity needs to be lowered, and/or ventilation in the van needs to be improved. You can do this simply by opening windows, using extractor fans but these tend to be power hungry, using dehumidifiers -and although there are some 12 volt dehumidifiers on the market, there efficacy is minimal- and using static dehumidifiers such as canisters of silica crystals, containers of salt based crystals and bags of moisture absorbing sand.
Of course not having damp clothes inside, covering pans and opening windows while cooking can help. A window is best left open when sleeping too as we give off large amounts of moisture as we breathe, it’s something like a half a litre per day. Constant ventilation is by far the best enemy of condensation but you could use some of the other methods mentioned to help you out.
All of these methods simply help you manage condensation, it’s a thing that is around constantly, but more or less on sunny, windy and rainy days: you can’t ever beat condensation completely. I know of one motorhome owner who blocked all of his vents and sealed every nook and cranny he could find on the basis that it would keep cold air out thus avoiding condensation. Of course what happened was the lack of ventilation made things worse because the water could not evaporate so he got much worse damp than he would otherwise have suffered.
On cold days in winter I run my fire at it’s lowest setting pretty much all night. Part of the reason is to prevent pipes freezing and to keep ambient temperature reasonable. But because the fire is lit and producing heat which causes condensation when it meets cold surfaces, it’s best to keep a vent or window open. Even during freezing days I find with the fire turned up higher to keep me warm, it’s best to keep a window open for ventilation. If there is any movement of air like from a light breeze, this actually helps the warm air in the van move around, which helps reduce condensation but even without a breeze the meeting of warm and cold air creates it’s own movement.
But if warm air carries moisture surely you’re making moisture by having the fire on? No, by having warm air you’re heating the cold surfaces to some degree, so that less water condenses. There are some who claim that they never suffer condensation and that you need extra insulation, or you have a leak, or some other excuse. It’s simply not true. Every motorhome gets it and as said at the beginning, you can’t change the laws of physics, Jim.
Most motorhome owners have a habitation service carried out annually and they always check for damp so take heed of any warning of dampness and deal with it quickly because the effects of damp can be unimaginably expensive.
Do some checks yourself for cold spots in your van, these are likely to be the places that condensation occurs; little used cupboards, underbed storage, overcab bunks. When you find cold spots check them for damp when conditions are ripe, such as when waking on cold mornings in winter, late evenings in winter when the heating has been on for some time.
If cupboards are packed tightly this restricts airflow, move some things out so that air can move.
On warm and windy days open your windows. It’s good for window rubbers to have windows opened regularly anyway and gives you a chance to clean the windows thoroughly and clean the rubbers. Oiling the windows every couple of years is also advisable to help keep the rubber in good condition.
Choose a method to combat damp, but check regularly and if it’s not working try a different method.
I did say I was staying around for market day and although Trip advisor said it was 9 am til 11 am on Sundays, market day is actually all day Saturday in Vila Nova de Cerveira. (Which I’ve found out means New Town of the Deer.) It’s well worth going in search of the deer up the mountain too 😉
The very large car park where all the motorhomes park was blocked off this morning with bollards: both the entry and exit. I saw one lad carrying a bit of fence along so I watched where he went and he was parked in a car on some waste ground that adjoins the carpark. He was putting up a sign that said people had to pay. So, block off the free, town car park, then open up waste ground and charge people for parking there? There has to be reasoning behind that but I’ve no idea what it might be.
Anyway I took Jack for a nice walk then left him in the van as markets aren’t the best environments for small dogs. They’re crowded and bustling and he could easily be stepped on so he was left in the van with a nice chicken strip to chew on. I got such an accusing look from him too. I half expected to come back and find something chewed lol
I made this panorama shot so you can see just how big it is. The scale of the vans in the centre of the photo gives you an idea as they are quite large vans. It was designed with plenty of room though so although it was busy and crowded I never felt hemmed in. I noticed a monotonous regularity of stalls though as I went round. There were only a dozen or so different types of things for sale, but repeated a dozen times. The prices on each stall were pretty much the same too so if a pan was €200 on one stall, it’s price didn’t very by more than a euro or two on the other ones. Jeans were common for €10 and shirts for €14, and each stall that sold them was pretty much the same price. Leather goods I noted were fairly inexpensive and that’s the first time I’ve seen that. Belts however were still silly prices with the cheapest one I saw being €15 for a very plain and simple belt.
As I walked round it was apparent people were haggling though. I did see one man haggling about a €10 pair of jeans lol Maybe it’s just what they do? I wanted a wire brush on a long stalk for some of the cleaning and rust proofing I’m doing to the van. I got a fairly robust one with brass bristles for only €2.50 which was a good price. I had one out of Poundland some time ago but it was rubbish and became useless very quickly. When I pretended to brush my beard with it and made a satisfied face and put a thumb up at the stall holder his face was a picture 🙂 Oh and a lady who was selling me a new wallet and haggling for all she was worth let off the longest fart I’ve ever known! She did not bat an eyelid and did not break stride with her chatter (whatever the heck she was saying) and even when I put my finger over my nostrils she simply knocked €1 off and wrote the new price on a piece of paper lol If anyone’s wondering I got it for €10 and as long as it is really leather than it’s a good price cos it’s exactly what I wanted.
An Englishman came up today to say hello. First time that’s happened to me I think in all the years I’ve been travelling. I was working on replacing the rocker cover gasket but sadly I don’t have the right tool for the bolts. It’s becoming increasingly apparent though that the head gasket might really be gone, so I may as well start biting the bullet and saving money up for this to be done. It’s a fairly large job and the garage in Germany wanted to do it for €2000! lol Anyway we had a good chat about all sorts so it was nice to meet you Martin and Pam.
At least I got the exhaust sealed up properly and the EGR valve seated correctly so that’s a step forward. So, my mission until returning to the UK in April is save money so I can get the head done when I get back there.
This is a pretty town with good enough shops and plenty of nice walks so I may stay around for another week. I’m off work this week so I can do as I like and maybe explore for a bit.
As ever here’s a few photos I’ve taken so far.
So, I drove at night to get to Portugal, and my Monzo card failed at the toll booths YET again Grr! But to be fair so did 2 Nationwide bank cards and a Santander bank card and my Revolut and Tesco cards. I was told in one shop today that they only accepted Portugese cards! Hmmm.
Anyway as Monzo doesn’t have any security on the app on the phone I’ve decided to stop using it. What’s that got to do with being in Portugal? Nothing really!
But this little town is lovely. It’s just what you expect from an old Portugese town and although it’s small, it’s really nice to wander around. Wednesday is my first night off work so I’m going to have a try of some of the little cafes and restaurants and bars over a few days.
I found an amazing shop called Hiper Bazar where everything is dirt cheap, and they sell everything. I got a new ceiling lamp for the loft, new cable cutters, a brass brush for the drill, 2 new hose fittings and a few other things all for €12. I may even go back again and see what else they have haha
The van doesn’t seem to be using any less fuel now the exhaust is fixed, and when I first start up there is still that smell of exhaust comes through to the cabin area. I might strip down the EGR valve and pipe connections again and make sure they are all sealed and fastened correctly. Also at idle it’s rattling so I wonder if they’ve loosened the heat shield or something.
Anyway I found the aire ok and there’s tons of room so I think I’ll stay here at least til the weekend. It’s bloody raining as usual so maybe if I wait it out I might get a sunny day if I’m lucky!
Where I stayed: Vila Nova de Cerveira, Viana do Castelo, Portugal, 4920. N41.938103, W8.746711 Free with waste dump and fresh water.
We haven’t travelled far in a couple of weeks as I’ve been arranging garage visits and doing some of my own repairs too. I found I had a leak from somewhere so I found that and sorted it and have planned a full reseal of the entire van.
Anyway, I came to Poio as it’s on the coast and me and Jack really like that but we found a garage here who agreed to weld the split in my exhaust pipe. We managed this with no Spanish at all from me and not one word of English from them, but the job is done now so all is good.
Where I am there is a lovely park right on the prom with some form of structure in the middle of the grass part of it. It’s obviously some form of art that has been put there probably simply for aesthetic purposes. Anyway, here’s the hat, on that structure, enjoying Poio beach even though it’s rained all day!
