I'm a regular customer and forum lurker in Autogeek. The product won't be sold and bought if it doesn't work.

The question is HOW you use it and WHAT you use it for.

Waterless wash is good for cars that are not soiled/muddy. Kung may dust, walang problema, tanggalin muna ang dust before i-waterless wash. In short, parang quick detailer lang sya na mas may cleaning action.

Personally, I don't use waterless wash. Ang dumi sa atin e. Konting ulan lang, yung putik sa kalsada, didikit na sa kotse.

Rinseless wash is the next step. You'll need water for this - although less than what you need for an actual wash. This can work on dirtier cars BUT not a very good idea if your car is constantly plying our streets during medium to heavy downpour - or relentless drizzling, since magiging maputik pa rin ang kalsada.

I do rinseless washing for maintenance since I don't go out often. Kung naambunan ng konti or di gaano madumi, or kakauwi lang and naulanan - pero di naman binagyo.

Kung di ka OC sa kotse mo, there's no point in doing waterless or even rinseless wash. Dalhin na lang sa suking car wash. Kumbaga, parang touch-up lang ang waterless wash to maintain cleanliness in between proper washing (at least sa Pilipinas, since sa ibang bansa or state sa US, may laws na nagbabawal ang paghugas ng kotse due to water shortage or environmental concerns).
