The procedure is easy, just read and follow instructions. Make sure to cover sensitive parts and do not use hard stream of water, sprayer is best for that.
Here are before and after pictures.
And a small video
Perfectly started after washing, no problems so far. Looks like a new ;-)
I will repeat it every year.
Recently (month or so) I felt bad smell when I turning A/C on.
The problem is known: germs and bacterias on evaporator make their job.
It happened that I saw Wurth products at Alon Halafim when buying oil, but on that moment he haven't A/C cleaner. When I came back to change oil, he brought Wurth QuickFresh (part no. 893 764 51) - don't buy this for cleaning, it's just add some fresh smell inside a car and cleans nothing. Cost around 50 NIS.
You need Wurth Air Conditioning Disinfectant Spray (0893 764 10) with spray hose (0891 764 12). I ordered directly at Wurth Israel, cost 116 NIS (delivery is 30 NIS to your house). One bottle enough for 2 applications.
You can check full working instructions at the bottom, but in few words:
1. Switch off A/C and ventilation.
2. Insert spray probe into filter housing and get to the evaporator.
3. Spray for about 30 sec.
4. Allow to take effect for 10 min.
5. Turn on ventilation and let it work for 5-10 min.
This is how I did this
Some tips for the future:
1. Do this once a year with filter change.
2. Dry evaporator surface as described in Luqui Moly doc before and after.
3. Better to use some air mask I guess.
4. When driving with A/C on, turn it off 1-2 minutes before you came to destination. This will dry evaporator and delay smell coming.
With this order I also wanted to buy Wurth High-concentrate windshield washer fluid (0892 333) - 3 little bottles that you can mix with tap water. But instead I got same 2 liters cans as I bought before.
Interesting, that at Alon Halafim it looks different. Cost around 10 NIS, great peach smell ;-)
