4001 Citrus Pre-Wash Car Shampoo, 1 L

Very good, dirt falls off the car and smells nice

I have 2/3 cars to clean monthly and this has been a really good pre-wash product. Dilutes at 8:1 water:cleaner and I still have plenty left. Good on alloys that aren't too caked in brake dust and pretty good at starting to shift grime on bodywork if left to dwell for 5 minutes or so. Dead flys however still need some elbow grease. Will buy again.

did the job very well, but make sure it doesnt dry and flush it well with water. Otherwise all goo

Keeping the car clean at this time of year is hell. Even a pressure washer doesn't shift all of it, especially on the wheels so I thought I'd give this a try after seeing a local hand car wash use a pre wash solition. I diluted it as instructed in a pump spray bottle -100ml of this to about 800ml water. That was enough to do an average sized car. I left that to sit while I got the pressure washer set up (about five or six minutes), then sprayed on my regular snowfoam. At this point, not much seemed to be happening so I gave the whole car body a rub down with a car wash mitt but it turned out this was not necessary. The dirt on the wheels (which I had not physically touched) just rinsed off. All of it! The dirt on the car body didn't put up a fight either. I only bought a 1 litre bottle to try out as I didn't want to be lumbered with a gallon of the stuff if it didn't work, but I'll def be buying a bigger bottle in the future. For me, the one litre bottle should do for about ten car washes. More if I just use it on the wheels throughout the summer as it just eats through all the brake dust and grime without having to faff about with a wheel brush. Good stuff!

Average cleaner. While it helps clean the car, it does not remove all tar and bug stains as claimed.

I used this citrus pre-wash as I couldn’t get my usual product quickly. I’m glad is don’t. The car was caked in bugs after a crabbing trip drive, sap and bird doo doo after sitting under a tree for for four days solid. More heavily diluted and after a spray treatment and rinse all was gone. Not a bug left and rough surface sap gone. Definitely using this in the future. Caravan clean next.

Good dilution ratio means it should go a long way. From watching videos on YouTube it seems like it’s a decent cleaner, easy to dilute

Makes it so easy to clean my car and makes it soo much easier to make it look brand new

Very effective.

Molto valido

Bof , je m'attendais à un produit efficace. Après avoir pulvérisé, le karcher n'a pas fait plus que si il ny avait eu ce produit. Déçu.

Buen producto. Deja muy buena olor

As a car detailer, I tried this stuff but does nothing.
