tl;dr: How much did you pay for that shirt? How often do you wash it? Why would you bother? Shirts just get dirty anyway. Can't you get another shirt? Are there any benefits of washing the outside of my car? Do you live in an area without salt, birds, tree sap, pollution, abrasive sand or road tar? Do you also drive around with brake pads that don't ...

The reason many people wash their car every week is to keep it looking nice and from the good old days of bad paint and no rust protection. These days, paints are significantly better and stand up to some serious abuse, and the cars are much better rust proofed (galvanised etc...). The washing your shirt analogy is a little unfair as with a dirty shirt, ...

I'll chime in with a totally different angle: Once or twice a year is fine unless it's getting covered in something nasty like tree sap or excessive bird poop. More important is washing stuff off the underside (where you can't see, and most corrosion starts) and fixing paint chips and other damage - again, underneath is more prone and very few people ever ...

I work from home, so my car stays in the garage for long periods of time. It doesn't get much mud or salt spray, and after it's washed, it looks pretty fresh for a month or two. It's often 6-months to a year between washings, and it never really looks terribly dirty (If it does get really dirty, I will wash it). However, a couple of years back, when I ...

Washing your car once a month is acceptable. It is not too much. What is more important is the technique and materials used (nonabrasive soap and sponge, drying towel, and wax). There are plenty of sites with tips on proper car care to cover this. Washing your car is a good thing because, not only does it keep it looking nice, it helps prevent corrosion as ...

I wash my vehicles whenever the temperature gets high enough to be able to do so during winter. A film of dried salt on sound paintwork or the e-coating on the frame won't do much damage, but wherever it can get to metal through porosity of or damage to the coating will initiate corrosion - which then creeps under the paint. What salt is used on roads ...

Apart from the obvious benefit that a clean car looks nicer, washing your car will also remove all sorts of stuff that, on the long run, will harm its exterior: Salt attracts moisture, which speeds up corrosion (which would not be much of an issue with a galvanized body and intact paint and clearcoat, but a 13 year-old car is likely to have some faults in ...

I wash my car before winter every year before it gets too cold. I give it a thorough detailing and then I apply 2 coats of hard wax to make sure I did a good job. This is my idea of giving the body some protection and it seems to work. After all it is a significant financial investment for most of us. You'll notice the water not sticking to the paint ...

LaserWash is a brand name for a touchless car wash system, which uses high pressure water and strong detergents instead of the traditional soap and rolling sponge gizmos. No lasers are used.

I assume that if you ask "Are there any benefits of washing the outside of my car?" you are not referring to the obvious cosmetic benefits. So I assume that the overall question is essentially summed up by the sub-question Does it damage my car if I don't wash it for a month or two? There is not much fact based evidence for an answer, with one exception:...

I go through car washes more often in the winter than I do in the summer, since I want to wash the road salt off as frequently as possible. I've never had an issue. I don't think I've gone through at -30c since we rarely get that low here (Toronto, Canada) but I've certainly done -15 to -20 without any problems (yet...) Automatic carwashes should have a ...

I have a 2004 Subaru Forester and have had it since it was about a year old. I can probably count the number of times I have washed it on one hand. They wash it when the oil gets changed at the shop but I don't drive much so that isn't very often either. It's pretty dry here but we get lots of snow in winter. They use gravel but not salt on the roads. I just ...

Theoretically, the thicker side has more surface area to absorb fluids faster like a sponge so using that side should work like a sponge. Because it's synthetic, it may not absorb water until its soaked, preferably with clean soapy water from washing the car. Once its soaked, rinse it in plain water to see how it absorbs then use it to soak up standing ...

I cant say for snow in particular (I've only ever cared for vehicles in Southern Cali, so no snow like you), but I'd think it's much the same as most cleaning/detailing practices. The major difference being icing. Obviously, one huge thing you can do is store your vehicle inside as much as possible. What I'd recommend is cleaning the car thoroughly at the ...

Wash it, got to be better than leaving salty wet dirt in contact with metal. Also make sure metal surfaces are clean, primed and painted - both sides...

I use these water repellent products frequently. Typically I hand wash my vehicles, however I have used automatic car washes too. In my experience, it doesn't really matter what the car is washed with (including the windscreen) as long as the repellent product is applied properly according to the instructions afterwards. Subsequent washing reduces the ...

You can still use a car wash, however it's always better to lightly hand wash a car, and keep the automated car wash use to a minimum. As after years of car wash use you will likely start to notice brush rotation lines in the paintwork. Agreed car washes have come on in recent years using softer brushes etc, but they still use filtered water and chemicals, ...
