I know some people will leave it for the next wash, but I just can’t get my head around starting the next week’s wash with a bucket of dirty ONR solution. I know that using BRS means dipping it back into dirty ONR solution, and the chemistry of the product is designed for that, but I would rather not have more than one wash session’s worth of dirt in the bucket.
I've got about 6 washes into my current solution, and I could probably manage a couple more depending on the cars. I will always encourage people to embrace new techniques and technologies with an open, albeit objective, mind. I think it's important for people to recognize their own cognitive biases, and make efforts to rectify them. The stigma that a dirty bucket will cause more scratches is very archaic to me if we're talking about ONR. The answer is undoubtedly much more nuanced than that.
This isn't meant to be an argumentative statement if that's how it comes across, just my thoughts. I'm a big fan of jumping right in and trying something the way the manufacturer recommends, because if I have to alter the process a great deal after trying something, it likely isn't for me.
This was where my approach broke down. If I am going over the panel with the BRS, then going over it with a wet towel like traditional rinseless, what is the benefit of the BRS pass? I used less towels to get the job done for sure; traditional bucket of towels rinseless takes me about 10-12 towels, and after the BRS I got away with maybe 4. I was using 800 gsm white ‘rags’ not sold here, and I like the white to see how much dirt is coming off.
In my experience I've gotten away with just two 16x16 towels to do all my drying (full disclosure: last couple panels take a couple more wipes with my final buff towel.) The damp towel is what I use to soak up the bulk of the solution/any potential dirt off of the panel. I find doing a rinseless wash, no matter what I can't get by with just one waffle weave towel. There's too much on the surface, and after the hood, windshield, roof, back window, and trunk lid, the towel is just about done for.
Using a damp towel, I can stretch just one other 16x16 (350gsm) towel far enough to dry the entire car without any issues at all. My damp towel does pick up some dirt sometimes, and if I run out of clean sides, I just put it into the bucket so I can agitate it, and wring it back out. That might make some people cringe, but I admit I have complete faith that ONR will work. The dirt showing up on a drying towel, especially for a pass with a damp towel (where both the media and the panel are saturated with solution) is a complete non issue in my mind.
It's also worth pointing out that the damp towel really is wrung out as tightly as I can possibly wring it out, and I also practiced this method when using the GDWM. After I'd used all the sides of my towel, I'd turn it to the low nap side, wring it out, and do the exact same damp pass to make drying easier.
If I’m doing a wet wipe after the BRS, then why not just wet wipe without involving the BRS step. I use more towels, but so what.
I think this is one of those situations where it's really going to come down to your preference. If you enjoy using the GDWM, I really can't see any objective reason for you to quit using it in favor of the BRS.
I am growing to like my BRS more each time I use it, but I'm willing to admit it doesn't clean any better than a towel does. In some cases i'd argue a towel is more thorough because it'll conform to a panel easier and fish dirt out of crevices where the sponge might struggle. I simply like having the solution mixed up and ready to go, I like only needing to grab 2-3 towels (3rd if I plan on wiping out my door jambs that wash, Just a generic low GSM black towel) instead of a dozen, I enjoy not completely trashing my towels even though I use cheap ones, I just overall enjoy the user experience of the sponge.
Any thoughts on improvements to my process to make the BRS efficient?
What I've settled on is: Pre-soak/pre-rinse (optional) -> BRS pass -> Spray D156 onto damp towel and make my first pass -> go over the panel with my final towel I'm using to dry.
