I've been reasonably happy with Dry Wash N Guard... Enough so that I
quit using Pledge a few years back...

The devil is in the details, of course...
Start with the 32 oz. with the pump sprayer to see if you like it...
Shake it WELL before decanting or using - and after you have it shaken
(not stirred), then shake it for double the time you thought was
adequate... There are some 50 ingredients in it and some settle out...
After the 32 oz. bottle gets low then the 64 oz. jug is good...

Oh yeah... On the pump sprayer, do NOT tighten the cap crushing the
O-ring seal, as this dents the O-ring and it eventually stops holding
pressure... Gently screw the cap down until you can just feel the
O-ring start to add drag, then add about one ounce of torque beyond
that... My O-ring on the pump is 4 years old and still going strong -
guys who just have to torque it down until it jams and the bottle
starts to distort will be lucky to get a few weeks out of the 0-ring
(gotta stop them leaks doancha know)...

It looks pricey but goes a long, long ways... ymmv, bni, sar, etc.
