The bicycle was quite rusty, so I washed it with water once.
I spent 6,000 won on car washing (2,000 won for water, 4,000 won for an air gun....)
It feels good to see the clean bike.
Looking closely,
the handlebar grip has some life left in it, but a lot of sweat has seeped in, so I think it needs to be replaced.
No, the whole bicycle seems to be due for an overhaul.
In case there are any beginners who want to wash their bikes with water,
spray it roughly from a distance with weak water (it's enough)
Use a high-pressure washer only for the chain.... between the links, between the links....
If you use a high-pressure washer on the drivetrain or all the gaps (damage to electronic components, DI2 battery, drivetrain bearings)
You need to remove moisture thoroughly.
And it's not good to wash your bike with water too often.
