Windscreen Washer Fluid: Choosing and Topping Up

Use handbook-approved washer fluid, avoid household detergents and top up the correct reservoir. Check spray coverage before dusty winter journeys.

1

Use the washer fluid and dilution your vehicle handbook specifies. Household detergent is unsuitable because it can foam, leave residue and affect components or finishes.

Can I mix different washer fluids?

Avoid mixing products unless their instructions confirm compatibility. Ask the vehicle or fluid supplier how to change an unknown fill.

What if I put washer fluid in another reservoir?

Do not operate the vehicle or affected system to try to clear it. Seek workshop advice immediately and explain which fluid went where.

Does coloured fluid prove it is suitable?

No. Colour does not establish specification, dilution or compatibility. Read the product directions and handbook.

Can I refill a rear washer separately?

Check the handbook. Some vehicles share a reservoir, while layouts differ; do not assume there is a separate rear filler.
