How to get rid of that annoying condensation.
When it’s cold and wet outside, the windscreen in the morning gets absolutely wet through on the inside. Warm air in the van condenses on the cold glass and creates lots of condensation. You heating creates it and so does your exhaled breath. There are a few options to help reduce this problem all with varying results and costs:-
Opening a window.
- Costs nothing.
- No storage requirements.
- Quite effective at reducing the condensation.
- Lets the warm air out and cold air in.
- Remember to close the window before driving off.
- Does not eliminate the problem.
Just use a cloth.
- Cheap and easy.
- Storage not an issue
- Not very effective and leaves lots of residual water.
Buy a windscreen cover for the outside of your vehicle.
- They have the advantage of keeping the inside of the vehicle warmer by keeping cold air off the glass.
- Very effective against condensation with little or no residual water.
- They are can be expensive to buy (they can be over £350).
- High storage space requirements.
- Can be a hassle to install.
- Might not eliminate the problem.
- No too expensive. (under £70)
- Small storage requirements.
- Removes all the water from the glass.
- Can also be used at home.
- Not the cheapest option on the market.
- Needs recharging every so often.
- Better than using a cloth.
We considered the pros and cons of each and opted for the window vacuum, there are a few on the market but we opted for a reputable brand and bought a Karcher WV2 window vac. It works brilliantly for getting the water and condensation off, whether its the windscreen or a conservatory back home. The battery life provides many days of use and charges up in 1-2 hours depending on how flat the battery gets. Sadly the unit requires 240v electricity but we have an inverter so it’s not a problem. However……
I had a look at the electrical output of the charger and guess what? 5v at 600mA. If it had a different connector on it could be charged up via a USB socket, so now I need a spare charger for it so I can cut the charger off and fit a USB plug instead, i can then plug it into a cig lighter adapter or computer to charge it up then instead of having to use the 240v inverter. If you have any thoughts please feel free to share.
Well it looks like Alistair (in the comments section) tried the DIY USB wire idea and it works perfectly and kindly offered to make us one too.
