Mr. Clean would have done it

The bottle would not be connected to our Kärcher model neither directly to the shut-off valve on the suction hose nor the pressure washer. So I applied the cleaner by hand on a large bow on the concrete blocks, which was again a feat, since the bottle can not be easily opened so.

That alone I found everything to be very inconvenient and time-consuming. Since you want to start and then you need only another 20 minutes to at all to apply the cleaner. And no, I have not two left hands.

The cleaner itself is relatively viscous (which is positive because it thereby adheres well to the cleaned stones), also cleans very well, but not better than a standard household cleaners. The amount offered here is only enough for about 30 m2, that is a double garage and two car parking spaces, and then only for a single cleaning cycle.

I also do not believe that this cleaner is more environmentally friendly than a normal household cleaner (as it says on the bottle), as in all cleaners iGuG like agents (detergents) are used and any commercially available cleaners nowadays must meet high standards in terms Umweltverträglicheit. The promised algae-stop formula and the promised wind and weather protection are well-intentioned sayings of the marketing department, but no more for me.

When the bottle was empty, we continued cleaning with an ordinary cleaner W5 by Lidl, and that worked just as well.

When I found it particularly annoying that the container was not emptied completely, and about one-fifth of the cleaner in the bottle was left as the very stable plastic of the bottle, it can not crumple, do not completely flow out quite viscous liquid and the excuse - stupid closure valve and a squeeze out is not allowed. I do not know who has what thought at Kärcher, as this product and its packaging have been developed, but that is not a functional solution for hobbyists certainly not.

I would not buy this product.

PS: So, a few days ago I threw away the bottle and there was about one-fifth in it, which could not be emptied. One would have to open the bottle with shears or a jigsaw ... alone that's actually a mess. That's totally developed by the customer.
