Waterless and no rinse (rinseless) are not the same type of wash.
1. Waterless: you spray waterless wash solution on a panel and wipe it off. Think quick detailer type routine.
2. Rinseless: you are doing the exact same thing as a conventional wash, except the panel doesn't have to have soap rinsed off it. You just dry it. The big benefit here is you don't need a hose, just a bucket(s) filled with water.
a. Conventional rinseless: uses a 2 bucket method. One bucket contains your rinseless solution and one bucket has water to clean out your wash media in.
b. GDWM (Gary Dean Wash Method) rinseless: use one bucket only, but many clean towels. The idea is
to forgo cleaning your wash media and just keep using clean towels. You never stick a towel back in your rinseless wash solution bucket once it touches the car. Normally people use towels for this and fold them in fours, so the towel has 8 clean sides. You can refold the towel to keep exposing a clean side (instead of rinsing your mitt out in what would be bucket #2)
Can use use rinseless / waterless together? Yes. That would be a hybrid wash. Which is better? Rinseless can handle more dirt, but you must still take all the precautions not to scratch your paint as you do in a conventional wash.
Rinseless products aren't miracle scratch proof products. You still have to take a lot of caution and use common sense. A lot of times people will do a hybrid wash by pre-treating a panel with a waterless product, then cleaning it with a rinseless product.
Which products to get? Well, you need to get a rinseless and/or waterless wash product(s) and some quality towels. Which brand is a matter of preference. If I was doing a "hybrid" I would like to have both wash products make by the same company:
- Pinnacle
- BlackFire
- Optimum
- Ultima
- DP
- Gary Dean
- HD Car Care
- + others
All make both types of wash products. Most of the rinseless products are priced similarly. The waterless ones is where pricing gets crazy. That's because the dilution varies widely, but prices are similar. All of them perform well. How safe they are is more a function of technique than brand.
Based on the waterless dilution, the two most attractively priced (waterless) are Pinnacle and Ultima. With Ultima, both rinseless and waterless are made out of the same product, and its very good. With Pinnacle, you will need to buy seperate rinseless and waterless products.
What else will you need for your "system"? Buckets, high gsm microfiber towels, and grit guard(s) [only if doing a non-GDWM type rinseless].
