I've been meaning to try THIS for a while as I've read very good things about 'ONR' on Detailing World. So I ordered some during the week.
It's great if you have difficulty getting a hose to the car, or you want to wash the car away from home at a show or meet for example. Also I couldn't wash the car last weekend as I would have left loads of water on the ground outside in the communal carpark which would turn to ice. This method leaves no water on the floor at all, you could wash the car in the garage if you have one large enough. All you need is a bucket, the Optimum No Rinse, a sponge or microfibre mitt, a couple of microfibre drying towels and just eight litres of water
It's basically like a car shampoo and you mix it in a bucket in the same way but you don't rinse it off at all. It's made in the US, and you just add 1oz to 2 US gallons to of water. Then using a sponge or microfiber wash mitt, squeeze out any excess so the sponge is wet but not dripping with soloution and gently, with very little pressure wipe over a panel, flip the sponge over and wipe over again. If the car is really filthy you may need to repeat that to ensure the panel is clean. Then immediately dry that panel with a microfibre drying towel. Then onto the next panel till the car is done. I did the wheels in the same way.
My car hadn't been washed for a month and I drive 350 miles a week so 1400 miles in all weathers including the last week of snow ice and salt! So about as filthy is it's ever going to get. I live in a first floor flat, so to use a hose and the normal two bucket method I need to throw a short length of hose out of the bathroom window, take downstairs a hose reel, two buckets, wash mitt, drying towels, wheel cleaner in a pump spray bottle, a large and a small wheel brush. Then move the car from where it's normally parked as I can't get a hose all the way out there, wash the car and then haul all of that back upstairs.
With the Optimum No-Rinse it's a simple case of fill the bucket, add the ONR, throw in the wash mitt, grab a couple of drying towels and walk out to the car, wash and walk back in twenty minutes later!
Yep, I turned my car from this:
(half way through I took this pic)
To this in twenty minues with just eight litres of water
You could justifiably ask is it as good as the normal two bucket method, a hose and gallons of water? Well the car looks just as clean as it normally does after I've used the two bucket method. I half expected to notice nooks and crannies where a normal wash would get clean, but all the nooks and crannies are just as clean. The only part of the car which I would say is washed better using the normal method is the wheels. Yes they are clean, but I normally use a fairly weak dilution of wheel cleaner sprayed on, left to dwell then brush the face and the drum and rinse off. With the No-Rinse I can't really clean the drum, but the face is clean.
This does go against the grain of using lots of water, rinsing the car off first, maybe snow foam, two buckets ect. You are basically wiping a wet sponge over the paint, so you'd expect it to cause swirls and fine scratches all over the place But the polymers in the ONR do lots of magic things and bind the dirt away from the paint so it doesn't cause any marring. I've seen a couple of threads on Detailing World where ONR had been used long term and has caused no more swirls than you would expect from the two bucket method. I deliberately used a white drying towel so I would see any dirt that had been left on the paint. And while it wasn't spotlessly white afterwards, it was no more dirty than I would expect it to be if I'd washed the car in the normal way.
So all in all, very impressed. I think I will now be washing the car once a week or more using ONR and then a two bucket method once a month or so.
