Screen wash in the AdBlue tank in Slough: a local drainer comes to you
The single most useful thing you can do now is nothing — leave the engine off. Then call 01295 380724. A drainer who works Slough drains screen wash in the adblue tank on the spot, flushes through and refuels, typically in 1 to 3 hours, with a call-out from £89 confirmed up front.
Screen wash thins the AdBlue out of its precise concentration, and the SCR system will throw a fault; the tank needs draining and flushing. Left sitting in the tank, it is a small job.

When a drainer arrives in Slough
Expect a van with a pump and a sealed waste tank. The drainer drains the tank, flushes the system through, refuels with enough clean fuel to reach a forecourt, then starts the engine and lets it settle. You do not need a garage and the vehicle does not move until it is ready.
Five things to ask a drainer before they set off
None of these are awkward questions. Any drainer worth calling will answer them before setting off.
- What is the total, not just the call-out, if it is a straight drain?
- Do you take card payment at the roadside?
- How long until you reach me in Slough?
- Is there an extra charge at night or at the weekend?
- Will you check the filter and pump if the engine ran?
What to do right now
- Leave the key out of the ignition and do not unlock the steering to push the car.
- If you are at the pump, tell the cashier; most forecourts will let the car stay in a bay.
- Call 01295 380724. Say what fuel went in, roughly how much, and where you are.
- Agree the price on the phone. Nobody travels until you have.
- The drainer pumps out the tank, flushes the lines and adds clean fuel.
- They start the engine, check it runs cleanly and take the old fuel away.

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 Slough.
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
How long does a drain take in Slough?
Usually 1 to 3 hours on site once the drainer arrives. Longer if the engine was started, because the filter and lines need flushing as well as the tank.
Will you bring fuel?
Yes. The drainer adds enough of the correct fuel to start the engine and reach a filling station.
Can I drive to a garage with screen wash in the adblue tank?
No. Every mile pushes the fuel further through the pump and injectors. A drainer comes to you, so there is no reason to move the car under its own power.
Do I need to stay with the car?
Ideally yes, so the drainer can confirm what happened and hand the keys back. If not, agree access on the phone.
Will my engine be damaged?
Not if it has not been started. The wrong fuel sitting in the tank touches nothing that a drain cannot clear. Damage starts once it circulates.
I only put a little in — do I still need a drain?
In most modern diesels, yes. Even a small amount of petrol reduces the lubrication the pump depends on. A drain is cheap compared with a pump.
