Koch Chemie Mehrzweckreiniger (Mzr) Reviews

This product rules supreme when detailing with stubborn, dingy, sticky, stank interior consoles. When you run up against cup holders, or some console nooks and crannies that have built up sticky grime, pull out the MZR. WOW! Was blown away the very first time putting this product to the test with a nasty mini-van interior. Spray it on, let it set for a minute and you will watch the grime loosen up. Wipe it off and smile. We typically use Pol Star for interior cleaning, but it struggles with built up gunk. Add some MZR to your arsenal and you will tackle anything thrown at you.

It smells amazing, saves you money, and it cuts down nasty interiors. Even if its not that dirty - just dilute it more and be safe about it, plus you save more money. All my guys love it at my shop and it works great.

My methods are pol star for maintenance detailing, (because of how much you can also dilute it and because it leaves a little bit of protection too)
and mzr for first time details, where a good cleaning needs to take place.
Koch chemie really has interior cleaning chemicals dialed down for detailers.
