Our second car is a Dacia Duster (sold as Renault Duster in some territories). We have a persistent problem with the fluid in the washer bottle getting gunged up with a black slimy substance. The washer bottle is a really awkward shape (it goes in where the outlet and pump is: see my photo below, but ignore the 'R') so is impossible to wash with a brush, and I've taken it out of the car every year to clean it out. There's a very fine rubber filter on the pump intake, which gets fully blocked by the gunge so no water can be pumped out.
Over the years, I've tried jet washing it out, sterilising it, used stones to shake the slime out, different cleaning products, but not matter how clean it is when it's replaced, the slime always comes back.
One suggestion is to cut out the rubber filter on the pump inlet, but I think that would just cause the slime to travel up the hoses and block the jets (and the one-way valve I installed to stop water draining back to the tank).
So, before I take out the tank again (for the second time this year), I'm wondering if anyone has any better ways of cleaning out washer fluid tanks, and any tips for keeping them slime-free. (I've always used concentrated screenwash, and have tried diluting it either with tap water, or filtered tap water, either boiled or not.)
Thanks in advance!
