It’s that time of year again… the mornings are getting lighter, the evenings longer and planning for the first trip of the year is well under way. But, what about your caravan or motorhome? It’s time for the de-winterising and annual deep clean. The easiest way we find to do it is to first create a list of the jobs to be done and make sure you have all the bits and pieces you need for the tasks. Our “go-to” shop for cleaning supplies is OLPRO, it’s easy to order everything for the season for both cleaning stuff and loo stuff. We have been using them for at least a couple of years now and haven’t come across any problems and have genuinely been satisfied with their products.
OK, so where to start…
As we don’t have power or running water where we store our caravan, some things might be a little easier if you do.
Pipes and Drains
I usually start by mixing up a solution of citric acid in water to pump into the water heater to perform a descale. If you look at your kettle and see the limescale buildup it will give you an idea of what is probably happening in your water heater too. I normally mix 1Kg of citric acid powder in 20 litres of water which gives a 5% strength solution. As this takes a couple of hours to do, its one of the first jobs we start so we can get on with other things. We connected up the container to the caravan water inlet, shut the drain down valve and pump the solution into the water system. We would need to leave this solution for about an hour, but to help speed it up we turned the water heater on. After 15 minutes I ran some water through all the taps into a jug and poured this back into the water container outside. We repeated this every ten minutes to ensure that all the solution had been pumped through all the pipes. After an hour, we turned the heater off and kept running the solution through another three of four times. It was now time to flush the system through by turning on the taps and letting it run through the sink drains to outside. When the container of solution was empty we replaced it with one of the 25 litre containers containing fresh water and pumped that through for a short while, letting it sit in all the pipes for 30 minutes. We continued pumping the fresh water through the system until the first container was empty. I connected up the next container and we repeated the process until another 25 litres had flushed through. As all the piping is PVC we were only really concerned about flushing through the hot water side and particularly the water heater.
Once all the fresh water had been pumped through, tasting the water told us it was fresh with no hint of citric acid. We then opened the drain taps to drain the system down. So now, hopefully the inside of the water heater is as clean and shiny as the kettle.
The guys at Meridianstar supply food grade citric acid in various sizes. We bought two 1Kg bags, so we have 1Kg spare for next time. Citric acid can be used to de-scale other food equipment… baby steralisers etc. so we don’t have any worries about after taste or introducing chemicals into our water system. They were also pretty quick in delivering too, it arrived 48 hours after ordering. (you can read the original article “Citric Acid Trip“)
Next – waste-hog and aqua roll. When we use the waste-hog, every time we empty it I always put about 50ml of OLPRO Fresh & Clear drain and pipe cleaner into the waste-hog it stops it smelling and I don’t have to worry storing it inside the caravan. For a through clean, 100ml and filling the container with 20 litres of fresh water and leaving it standing for a while, occasionally swilling the mixture around. I do the same with the aqua roll. We can now get on with other jobs.
Sue usually tackles the loo next while I take care of the loo cassette. Over winter I drain down the toilet header tank so usually have some of the fluid I drained out in a container I can put back in the header tank. As we use the Top & Bottom Plus for both the toilet header tank and cassette, it’s an easy matter to replenish everything. I usually double the recommended amount of fluid for the first fill up of the season. After that we just use the recommended quantities.
Next… Inside, well that a bit of a mystery to me as Sue disappears inside with a load of cloths, a bucket of water and a container of Inside & Out 7 in 1 caravan cleaner. You can find all the chemicals in the OLPRO Shop under “Essentials – OLPRO Chemicals.
The lack of running water is a bit of a pain, but we found a way round it. I put a few litres of water in a plastic tray that allows me to use a long extendable handle brush that is designed for cleaning vehicles, I pour in some of Sue’s Inside & Out 7 in 1 caravan cleaner (Yep it really does what it says on the label) and commence cleaning the roof. We usually take a couple of pairs of steps with us to help. Dipping the brush in the tray of foamy water easily allows me to clean the roof without laying or stretching too far. Now here’s my trick for rinsing it off. I use a garden pressure spray – the type that allows you to put in 3 or 4 litres of weed killer and pressurise it with a pump handle. I have found that 3 litres of water will easily rinse the roof off. (Note: I only use this spray for washing off the caravan!) Once the roof is done, it’s usually time to nip back and swill the warthog and aqua roll about and pump the citric acid solution round the heater again.
TOP TIP: I use the pressure spray to rinse off the windows BEFORE I wash them, it helps wash off the dust that might cause scratched in the polycarbonate.
Tackling the sides is much easier and done in the same manner. Brushing the sides and rinsing off with the pressure sprayer. As each side is finished, a wipe down with a microfibre cloth to dry it off stops any watermarks appearing. The next thing to tackle is the plastic around the lockers and the Fiamma awning bag. We have found the best way is use a slightly more concentrated solution of Inside & Out and use a small brush… it’s a bit like a big tooth-brush really, I think we got it from a bike shop it was meant for cleaning mud off bikes. It makes short work of cleaning the textured plastic surrounds of the hatches and the zipper on the awning bag. It’s also great for cleaning inside the upper and lower awning rail tracks.
Time to go back to the start and empty out the warthog and aqua roll and pump some clean water through the heater to flush out the citric acid solution. In all it usually takes us the best part of a day to do a through spring clean on the caravan. As we usually hook up the car to the vehicle to pull it forward so we have more room, I also take the time to check out the tyres looking for cracks in the walls on both the outside and crawling under the van on the inside. We can also check all the road lights are functioning (although after changing over to LED’s for the road lights I haven’t had any issues at all) and I also do a basic safety check on the earth system, checking for continuity. It’s also a good idea to check out the gas pipe for the CADAC BBQ that we use to plug-in to the external gas point. I also take the time to spray some grease on the steadies and wind them fully up and down a couple of times. A quick inspection of the 13 pin plug and a quick light spray with Boeshield T9 to keep in tip-top condition.
So, that’s it, all set for the first trip!
OK, so how much water do we use? Well we take three 25 litre containers with us. On has only 20 litres of water with the citric acid powder added making a 5% solution, The other two are full of clean water. One is used to rinse through after the using the citric acid solution, the second for actually cleaning the caravan
