Hhmm.... okei, I'll share with you on my thoughts on this but they're solely just opinions and suggestions and thoughts.
We'll need some kind of sponsorship. The car wash washing liquids (soap, etc.) are not that expensive per bottle, but if we're going to wash lots of cars, 4X4's, etc. then we're going to need lots of it and when there's lots of car wash soaps, there's bound to be money involved. Thus, perhaps some kind of sponsorship would be good.
Washing material like washing cloth, drying cloth, sponge, etc. would have to be stuff that's meant for use on cars. Careful handling of customer's cars would also have to be taken into serious consideration. However, some customer's could be just assholes. You know la, some people never notice a scratch on their car and after washing, they come and say, "Hey, you scratched my car!" You know, that kind of people.
Water supply would probably be the most important of all. I think the place that we use to perform this charity wash would be the place to provide the water. Some sort of an agreement would have to be worked out with the owner of the place to use their water and their place. Once that's worked out, we've also got to figure out how to distribute the water supplies so as to have multiple sources. This will allow more cars to be washed at once.
Drying area. I think a shaded area would be required so as not to leave water stains on the cars. Also, we may need to consider vacuum services as well, if we're planning to provide vacuum services. Once we've erected the drying area, we may want to consider "drivers" to drive the cars from the washing area to the drying area. This is to that those who wash the cars will not need to go into the car. Why so is because the "washers" would most likely be sweaty / half wet / splashed with water / etc. so it wouldn't be quite a good idea to get into the customer's car.
Payment counter. Someone trustworthy would have to be the cashier. We may also need to bring some chairs / stools / etc. for customer's to sit down while their rides are being washed.
These are just some thoughts that goes through my head about this thread.
Since elaine2284 mentioned about extreme park, I think that's one of the best place to have it. The Sunway Petting Zoo (located inside Extreme Park itself) is a good place. Why?
1) Big and spacious car park, but under the hot sun! hehe
2) There's a roofed cafe for customer's to rest, drink, eat a bit while their rides are being washed. There's also large fans with fine water spray to cool the place. This saves us to bring chairs. The payment counter can also be located there for ease of payment and not so hot also.
3) The customer's can visit the Sunway Petting Zoo while having their car washed. hehe
4) "Free" publicity for Sunway Petting Zoo, which from the way I see it, is not popular even after 1 year of operations.
5) Location is away from main road, heavy traffic or any kind of traffic so the charity wash probably won't cause much traffic woes. Well, unless we get like a few hundred cars coming in, then I have to shut my mouth on this point liao. hehehe
Moving on, perhaps these are some ways we could work it out.
1) Come to an agreement with Sunway Extreme Park management to provide the water and a section of the car park.
2) A good time frame to pass flyers around or advertise in the papers would be a good move to gain publicity.
3) Tabulate a price range for different type of vehicles like those you see in car wash places. For example,
- Car : Wash only = RM7
- Car : Wash and vacuum = RM9
- Car : Wash, vacuum, and engine wash = RM12
- Car : Wash, vacuum, one round of spin in BlackHowling's 500bhp Supra = RM20
- Car : Wash, vacuum, one round of drifting in ninja_iga's Titanized Kancil = RM18
- Car : Wash, vacuum, ride in a 4X4 and see how Satira_95 crush rempits LIVE before the customer's eyes = RM30 (rain coat with hood and goggles provided in case blood splatters all over the place)
Hope that helps a little. I'll help out with the washing.... of the lady customers in a private bathroom and it comes FREE with any car wash package. Only applicable to "hot" ladies who needs to "cool down". hahahaha
