Ah, a self-service one.
How much does that one cost?
I feed ฿20 notes and can detergent and power rinse my whole scooter for ฿20-฿40 or another ฿20 for air if I want to blow dry.
Even just ฿20 quick spray detergent on wheels and mudguard splash zones + power rinse quick brings the scoot up looking really good.
I always use the gentle fan pattern spray standing well back from the ADV350 when power rinsing, so as not to force water into places it should be (which is all too easy to do with high pressure).
The detergent is very effective at releasing dirt and plentiful...not just foam but a good quality liquid.
I'm always very careful to rinse off, making sure the water coming off the ADV350 is completely clear (no remaining detergent whatsoever).
I saw a new brand Triumph in Chiang Rai that hadn't been had detergent 100% rinsed off and it looked like it had done 5 years in a British winter with road salt (for freezing road conditions). All the alloy laquer had failed.
There's a bucket of water setting too.
Pro tip (haha) If you actually press the on off buttons until the lights off it stops the timer count down. So if you really want to get into rag'n'detergent in bucket and hand washing, you can really eek out your moneys worth. The staff showed me the button on off tip.
The male attendants/staff are relaxed.
I even strip my ADV350 clutch / variator / belt cover and use the airline to blow out all the dust build up every 5-10,000km. The air line nozzle is really good.
