Cappuccino windshield washer bottles, a la Nopro, cheap on Rakuten.
Nopro came up with the idea of using Suzuki Cappuccino windshield bottles and nicely tucking them away in the cowl. Suzuki is selling them on
Rakuten for really cheap, ~$35 shipped EMS to the US. Compared to about $160 from Nopro.
Mounting it is an easy DIY job, written up by AgentOrange here on MR, as well as Revlimiter.
I haven't had wipers for years but ordered one just to have in case I decide to put them back on. It is actually raining in California this year.
