rm20 per car isnt that a bit expensive ? and besides that, you need to pay for epf socso, etc. its a good business if you manage to get many customers, the problem is its not easy to start cause ppl dont trust you with their vehicles, most places i go, ppl need to trust the car wash person in order to leave their car and collect later, seldom sit there wait for you to do the job, you need to protect the vehicle from theft, imagine somebody just pretend to be the car owner, pay you for the wash, are u going to pass him the key ? are u going to responsible for lost vehicle or they blame you for unable to start the car later cause of engine getting wet ?

you need to put everything into consideration, good ones and bad ones, imagine there is another car wash nearby and claim you stealing their customer, and they are fiercer than you, got police and gangster behind their back, how u going to handle ? what if raining almost every day, how long u can last ? what if your worker scratch your customer's expensive car or break the windsheild, are u going to cover ? what if no water supply after u get a few wash jobs ? Its a business and you need to seriously think about that.
