AdBlue in the screen wash tank in Croydon, drained on the spot
Stop, switch nothing on, and call 01295 380724. Local drainers across Croydon handle adblue in the screen wash tank every week: tank out, lines flushed, clean fuel in, all where the vehicle is parked. Expect 45 to 90 minutes on site and a call-out from £89, with the full price given before they leave for you.
Here is why it matters. AdBlue in the washer bottle leaves a crystalline film on the glass and attacks seals and paint, so the bottle and lines are drained.

What the drainer does when they reach you in Croydon
On a forecourt the drainer will usually move the vehicle off the pump lane first, by hand, with the engine off. Then it is drain, flush, refuel and start. At home or at work they can do the whole thing on the drive or in the car park without moving it at all.
Five things to ask a drainer before they set off
A drainer should be happy to answer all of these on the phone. If they will not give a price before travelling, ring someone else.
- What is the total, not just the call-out, if it is a straight drain?
- How much more if the engine has already been started?
- Do you bring clean fuel, and is it included?
- Do you take card payment at the roadside?
- Will you check the filter and pump if the engine ran?
What to do right now
- Stop. Do not start the engine, even for a moment.
- Note the fuel type, the amount you put in and whether the car was already low.
- Ring 01295 380724 and give the location — a postcode or the filling station name is enough.
- Get the full price and an arrival time before you agree.
- A drainer attends, drains and flushes the fuel system where the car is parked.
- Clean fuel goes in, the engine is run, and you drive to the next forecourt to fill up.

From the drainer's notebook
Fuel Fixer, the company behind Wrong Fuel Drain, holds a rating of 4.8 out of 5 from 2,190 reviews on Trustpilot, on a profile claimed since 2017.
Across recent reviews, the themes customers raise most often are staff who stay polite, professional and reassuring during what is a stressful situation, and how quickly a technician arrives and gets the vehicle back on the road in Croydon.
The most common criticism is price. Some customers have felt the cost of an emergency drain was steep for a job that takes under two hours, and that is fair comment on an emergency call-out. It is why the misfuel call-out fee now starts at just £89 and why the full figure is quoted on the phone before a technician sets off — so nothing about the cost is a surprise at the roadside.
Common questions
Can you drain a hire car or a company car?
Yes. Tell the hire company or fleet manager too; many prefer a drain on site to a recovery.
What if I have already driven home?
Leave it on the drive with the engine off and call 01295 380724. The drainer can do the whole job at your house.
What happens to the fuel you take out?
It goes into a sealed tank on the drainer's van and is taken for licensed disposal and recycling. It is never tipped away.
Do I need to move the car off the forecourt?
Only if it is blocking a pump. Push it into a bay with help and the engine off; the drainer can work there.
Do you cover all of Croydon?
Yes — forecourts, roadsides, homes and workplaces across Croydon and the surrounding area.
Can you drain a van or a lorry?
Vans, yes, routinely. Vehicles over 3.5 tonnes are quoted separately because of the volume involved.
