I used to be real anal about keeping my bike clean. I ride year 'round (well mostly, I don't ride when it's this damned hot!), and it ALWAYS seems like as soon as I clean it up, it rains! I wash with whatever is handy. I've used car wash pressure washers MANY MANY times, but I probably use my garden hose the most.
The electronics are sealed. You aren't going to hurt anything (factory) on the bike as long as you aren't applying the pressure DIRECTLY on the dash. I tend to stay about two feet back from the bike if I have to use a pressure hose. I just 'fog' the spray on it and that works fine. I always carry a towel with me.
wiping it down/washing it off with a wet towel then drying is all mine has ever got. And people ask how it stays so clean on trips. Well the hotels hate the condition I leave their towels
Hey all, if you are at a hotel and WANT a towel to use on your bike, ASK! They almost ALWAYS have plenty of stained towels that they are more than willing to give you. I had a very frank discussion with a hotel owner who was hesitant to give us a room, because "you guys always tear up my rooms, and ruin my towels" That is an EXACT quote. After assuring him that I wouldn't tear his rooms up, or ruin his towels, I got the room. Later, he offered a a box full of towels with spots of some sort that wouldn't wash out. They were almost always a wine food stain, or dirt or something. He let me dig through the box for towels I wanted. He even told me to keep them!
Any way, if you have time and so desire, wash away. The Connie can handle it! However, as previously mentioned 1,000,000,000 times, DON'T use dish soap on your vehicle!!
I'm not stirring chit, but it's too easy to ask and get good clean towels to use.
