Chemtech's CT18 Superwash is not only a well known cleaning product for its ability to cut through tough dirt and grease, it's also Australia's No.1 concentrated cleaning gel. This large 20 Litre bottle, is ideal for commercial applications such as detailing businesses, and fleet management.
I'm not too keen on using this on cars….personally I think it's too harsh - strips polish and wax. I use Meguiar's Wash and Wax.
I do use CT-18 on the alloy wheels though, spray a 50/50 solution with water and let it soak. Really helps clean off brake dust and grime.
I'd also use it on work vans/trucks, or a car I didn't care about, but not my car, no.
It is not as harsh as it used to be, it's now pH neutral and perfectly fine for washing the car.
I used to use it as a foaming pre-wash, foam on, rinse off, and then 2 bucket clean with Autoglym car wash.
is this stuff suitable for washing exterior house paint?
I've used it on a particularly dirty patio before, and no problems that I saw, and that included painted surfaces.
I don't see a problem, just don't let it dry onto any surface. But that goes for pretty much every product out there.
At the price of some fruit juices…
So. is it a general cleaner, or
mostly for car bodies, etc…?
