Late to this thread! As much as I’d like to clean my car weekly or even fortnightly, life means it gets done as and when the stars align! Sometimes it’s weekly, other times it’s weeks apart. So I’ve ticked the last option in the poll.
On the ONR topic, I bought a bottle of it a good while back, after a recommendation from another detailing enthusiast (who’s opinion I value) on another forum. Whilst I’ve yet to do a wash with it as its intended use (the car has been very dirty come wash time and I have a fairly new Kranzle K10 pressure washer which is such fun to use that doing a almost waterless wash is a travesty, lol), I do, like Mutley75, add a capful to my shampoo bucket, and agree, it notably increases the lubricity of the shampoo and reduces friction between mitt and panel. I use a very lubricious shampoo anyway but even so, the ONR adds more and whilst it slightly knocks back suds, it’s the lubricity which is the more important thing. Come the better weather or if the car is only mildly grubby, I’ll definitely try ONR for a full wash, but for now it has a place in the routine as a supplementary wash aid. Good stuff!
