It's co-incidental that this thread has been re-surrected. We had a representative from a detailing Company/Supplier hold a seminar at our most recent Club meeting. Apart from other things, he asserted that you'd need at least two buckets of water to was a car properly, and that sponges were a no-no. A soft fibre cloth was the distinct preference.
I have to admit to using a sponge - two different units for top and bottom of the car. Pror to drying the car, I let water run gently all over the car and all I have left to dry then are simple water beads. I use the Kanebo brand of chamois. I also have a Meguiars (?) that's not worth a pinch of salt. It came as part of a car cleaning package. Regards Styria
I guess its horses for courses Styria and of course everything these days caters for the lowest common denominator (AKA The Idiot consumer) hence the sponge issue.
We all usually KNOW that dirt is an effective way to ruin a nice paint job so we start with a relatively grit free car and use caution and good sense.
And if we do use a car sponge then we buy a quality item and then break the sponge in to soften it and remove any nasties before we use it.
We also now have Environmentally sensitive marketing which while all good and well don't apply to a lot of us who have the forethought to save rainwater for car washing.
I have used Microfibre items for a while initially from the Enyo (?) range which I was told worked best without nasty detergents but i found worked even better with a good detergent lol and I even buy microfibre rag bags as they have a little more oomph when removing road grime.
But all in all I rather like sheepskin mitts and the final wash is usually done thusly on any car I take pride in and as for 2 buckets?
I think I used 300 or so litres of water per car wash for a good well rinsed result so old school products do just fine.
Hell even Kitten Glo Wash still gets a bit of use on the daily driver lol
If it works for you? Keep using it
