Rotten eggs smell when washers used
 

Strong rotten eggs smell when using the windscreen washers on my V6.

I notice I have wires following the water pipes to the outlets on the bonnet which I assume are for heated washers.

Last weekend I emptied the reservoir by continually using the washers and then refilled but still the same. Any ideas or is a bumper of job.

Stubs

Bacteria thrives in the washer bottle and i have always found that using winterwash all year round stops it's growth , good idea would be to empty the bottle and fill it up with said stuff , the high alcohol content stops the bacteria growing .

Just my opinion of course .:D

Sounds like the reservoir needs cleaning out. Mine used to stink until I cleaned it out with bleach.

Stop putting eggs in the bottle

It is whats known as a bio film which is growing in the bottle causing the smell, pop in a couple of Milton tablets and leave for a while, then flush through.

The bugs feed on the detergent in the screenwash. This is basically an anionic sulphate/ether sulphate, so contains sulphur. The bacteria are primarily anaerobic, so in munching away at the detergent, they generate hydrogen sulphide. This dissolves in the water and when you spray it on the screen, it pongs of rotten eggs. Screenwash formulas often contain isopropanol, which acts as a cosolvent and antifreeze. Bugs don't thrive in alcohols, so the winter formulas are usually pong-free.
A couple of days treatment of the tank with a spoonful of Domestos will kill 99.9% of bacteria. Or is it 99.99%?
