Usually people in the industry uses Karcher Puzzi, but if you are looking something affordable, there are some options out there, for example this "Iris Ohyama Rinser Cleaner RNS-300". If you dig around in shopee, a lot of these affordable machines around, search for keyword : fabric upholstery cleaner.

I do not know how they perform, but for this you can always search for reviews on youtube. Like the Iris Ohyama cleaner seems to have quite a few youtube reviews around. Have a look to see if it fits your needs.

Hope this helps

Not sure how is your process, but can consider watching and following the below Youtube video (first half). Can substitute the detailing brush with a microfibre cloth if you dont't have one.

My simple recommendations :

-Dont immediately jump to polish with machine & DIY ceramic coat your car. We go back to basics first.

-Buy clay bar to solve car paint being rough. Any brand is ok but I personally would avoid cheap 3M ones. Watch youtube on how & when to use clay bars. Can try to use diluted car shampoo as lubricant to save money.

-White cars will get black stains or turn yellow easily, advisable to get 'all purpose cleaners' type of products to clean these. If you want to save money, Sunlight dish soap diluted 1:4 with water & stored in a spray bottle works well to spot clean black stains.

-Protection products : Important to invest in a good branded spray sealant product to protect your car after cleaning. This helps keep your car cleaner for longer and avoid dirt from 'becoming too stubborn'.

-The above should be the sufficient to maintain your car, can try these out first then only go to the next level to do polishing if required.

Enjoy the process

Sounds about right as OSREN's bubble & wax should be a less concentrated shampoo judging by it's dilution ratio compared to the good old Nano Wash. There's another thing you can do to get thicker foam from your current setup, which is to change the foam cannon orifice size.

Your MJJC foam cannon might already provide your with an extra smaller sized orifice that you can try, if not then you can consider buying one, i recommend this seller, can message the seller for advice on which size best suits you.

I see, alright, and yeah, I miss Nano Wash as well, I quite liked it

Using acid car shampoo for waterspot monthly is a bit extreme, also you dont mean those black lines right? it's the rain spot marks, right?

I'd say prevention is better than cure : I'd recommend using a decent spray sealant to protect & prevent stubborn waterspots rather than using acid car shampoo monthly.

I see. In the market currently these are the only 2 acidic car shampoo.

There is another option which is to use the common "Watermark Remover" product out there, it's much more affordable but it has it's risks as they are usually quite strong acid, you need to know what you're doing with it.

I still do strongly recommend aapply spray sealant on your coated car afterwards, it does help reduce stubborn waterspots and stains.

I tend to use more osren products so I'll recommend their paintwork coat / Hydro Ceramic Shield, but similar products from any reputable brands should work fine as well.

regarding using 'watermark remover' products on coated car, you can refer to this Youtube video, hope this helps.
