Screenwash ......
Took the 745 out for a quick cruise today for the first time in several months. Started on the 'button' although battery clearly needs a charge and everything sweet except .....
..... the water flow to the windscreen front jets (forgot to test the back!!). Front screen jet in-tank pump working but no water coming out the main supply pipe from the pump which tested at the under the bonnet 'T' piece connection before going off to the jets. I am pretty sure that the screenwash additive has gone 'all cloudy and gunky' in the tank as my top-up bottle in the garage looked like a milk shake. I know this is a problem with modern ethical additives. Clearly I am going to have to waste time and energy removing the air filter box etc etc and cleaning out the tank and checking the pump. If anybody can recommend a screen wash additive that does go all modern and 'crapy' I would welcome recommendations. Cheers, Bob |

I would recommend running high alcohol content screen wash, basically anything rated to -10C. I use that all year round and stops bacteria and things growing in the tank. I quite like the comma xtreme
Also helps keep the wipers from getting summer grease I find.

White vinegar (preferably the NBC stuff - no yeast as it's not brewed) is also good for helping to keep the system clean, perhaps once or twice a year depending on use. Just add a pint to the washer bottle and top up with water.
Remember the pre-Windolene days> Water, a shot of vinegar and all your house windows nice and clean! Same applies and it also helps remove limescale too. One of the "ethical" things that still works! :thumbs-up:

Halfords concentrate.
I had a similar problem many years ago when I first owned a car with the washer bottle hidden in the wing. I had made up a 5L bottle of diluted wash fluid which I kept on the garage. At that time I was using Comma fluid. After a while my washers ceased working. I found that the inline filter was completely clogged and I could not clear it so I removed the filter until I was able to obtain and fit a replacement. A check of the bottle in the garage revealed that the made up solution was full of crud as you described so I checked the fluid bottle in the car and found it to have the same problem. I gave the system a good clean through and tried Halfords concentrate which I diluted depending on the expected ambient temperature. I have not had any further problems. The premixed bottle in the garage does not deteriorate over time.

Plant more trees, bushes and plants, bring our hedgerows back and keep running petrol cars! Oh yeah, give us back some proper screenwash that doesn't turn to snot in the bottle!

Avoid methylated spirits for sure. Many years ago someone I knew had a brand new Cavalier SRi as a company car. We both worked for a pharmaceutical firm at the time, where meths was in plentiful supply (don't ask!). So Pete (the flash geezer Sales Manager type) dutifully kept the SRi's washer bottle filled with the stuff.
After about a year he came into work one wet morning shiny suit and shoes all decidedly damp. The meths had quietly destroyed the windscreen rubber seal. Exit stage right one chastened flash git...………. Jack |
