No secret here, I pull out my Walmart pressure washer, soap setting first, then rinse with fan spray only, then blow dry with air compressor. I'll use some degreaser on engine parts if necessary.
If I have time I'll apply tire dressing, I almost never use polish.
If you avoid riding in the rain and use a cover even when in the garage washings will be few and far between.
I use S100 cycle cleaner. Spray it on, hose it off with low pressure, towel dry, then air compressor, towel dry again. Fire it up, ride it around the block, touch up with towel.
Someday I will try a diluted mixture of Simple Green.
I use Denatured Alcohol, aka Shellac Thinner, for final wipe down on chrome surfaces for streak free shine.
