Oberk MPX MultiPurpose Cleaner is an all purpose cleaner with a higher pH than Oberk's APS, yet still retains a high level of surface safety. Pairing up alkalinity with a waterborne solvent, stronger cleaning power is achieved within the full range of how an all purpose can be used in your detailing work. From interior surfaces to cleaning wheels and tires, simply adjust your dilution ratio to clean. MPX represents a stepped approach to cleaning, less aggressive than a flat out degreaser, strong cleaning without going too far... an effective all-purpose mid step solution. The internet loves a great 50/50 cleaning shot, yet a degreaser strength solution is not suitable for constant and repeated use where color fastness is a constant concern. MPX delivers a component to your cleaning arsenal with a balance of strength. Uses: Wheels & Tires Interior textured plastics Engine bay Suggested Dilution Ratios 1:10 for interior surfaces and more mild exterior cleaning 1:6 for heavier soiling on exterior surfaces, wheel and tire cleaning Precautions avoid use in direct sunlight test areas of application, especially on interior surfaces and carpets to ensure color fastness cool surface use only monitor dwell time on any surface I want to note that with there being a waterborne solvent in MPX, do not expect a sudsy cleaner.
