1Z Einszett Windshield Wash Booster Review

**SON1C** · 09-03-2014, 11:52 AM

nice review! I`ve been testing this over the last few months as well

Angus, I was going thru the post and trying to figure out what`s what. I`ve been using this product for a couple years. I`ve used it as a "booster" added to pre-mix ($.99) washer fluid:

The stuff totally kicks a$$ like nothing I`ve seen before. I thought it was a booster but I guess it`s really 150 ml of concentrate intended to yield one gallon of summer washer fluid. The packaging and labeling on my bottle is similar to yours yet there are differences. I wonder if it`s the same stuff?

I guess I need to order the stuff Jesse just reviewed and I`d like to try their winter concentrate.

I`ve got the P21S and WURTH booster in the basement. This stuff embarrasses both of them. It`s quite impressive!

Yes sir, looks like the same product to me. I love it for warm weather. Going to switch over to it this weekend in fact.

Did your 5oz bottle come with a 1oz measurement cap? The 8oz ones do.

I`ve never tried the winter concentrate due to the steep cost. You`d need to spend a small fortune on it to make it through a winter!

My bottle is sort of a single use with a tear-off/twist-off top:

My only concern about this is I probably don`t go thru 5 litres of washer fluid during the entire year, let alone in half a year. Personally, I think I`m better off using winter juice all year round. I would hate to have to suck out "winter" juice to replace with a summer solution -- it really isn`t practical.

(All our vehicles have 5L containers.)

*Bump*

Just made up a fresh batch of 1z Einszett Washerfluid using the last ounce left in the bottle from this review. Really love how easy it is to make up a fresh batch of washer fluid whenever I need to. Plus it smells great!

Same here. I run this every year, works awesome. The only thing is you still need to clean your wipers when it`s pollen season...

I hate that green dust!

**tom p.** · 05-02-2017, 05:37 PM

I`ve purchased most of their glass products now. They`ve got some great stuff!

**rlmccarty2000** · 05-02-2017, 07:26 PM

Now this is timely! I just bought my first bottle this week. I fell in love with 1Z Windscreen Cleaner and was hoping this would be a good complementary product. Now if I can get around to actually mixing it up and putting in in the car...

**rlmccarty2000** · 05-02-2017, 08:25 PM

Noticed on AG that the bottle has changed and since I just bought some I had to check.

Yep, new bottle and now Nextzett.

I can`t wait for pollen season to end. Ugh.

Yes they do! Plus everything has a nice subtle lemon lime scent

Awesome! Glad I bumped this thread. Enjoy it

I also noticed they have 2 different measurement lines now. I guess those are based on washer fluid tank size? Although 5L = 1.3gallons and 2.5L = .66gallons, I`m not so sure how those marks are useful to us on this side of the pond when mixing up a fresh batch in a gallon of DI water...

Just mixed up a few gallons and added the first one to the tank this season. Cant stress enough how big of a difference this stuff makes during the summer months!
