Cleaning car

Hi you all car pros. I have my first pressure washer. A karsher with 2 section for soap.

I was wondering I don’t need a foam gun correct ? I can just put water on the car then turn to soap and put soap and then clean right?

Then which soap do you recommend to use in my karsher to clear the car

Be careful with a pressure washer on a car. Do not get too close to the surfaces as the pressure is very high and can damage it.
Use car wash soap for washing. Never use dish soap.

Oh, I suggest you never use a pressure washer in the engine compartment. The high pressure mist and water can get into everything and give you all sorts of electrical problems.

You just need to cover the alternator, intake and battery with a plastic bag and let everything dry before running either by time or compressed air.
Its not a huge deal with modern engines as rain already gets in there.

2017 WRX did an engine bay detail after the last 2 winters.

Just experience talking but I would never again pressure wash an engine bay.
If rain gets in you have larger problem LOL

I've washed engine bay many times with pressure washer with no ill effects. Just use your head and don't aim for any electrical stuff, and keep some distance to reduce pressure. Dry it with a leaf blower after, go for a drive and leave the hood up after to let the warm engine evaporate any leftover water.

I hope the hood scoop is directing air into the intake and not just all over the engine compartment.

The soap dispensing containers is not the same as a foam gun. A foam gun will produce thicker foam that sticks to the car better than the soap containers. As for what soap, pretty much any that's meant for car washing. I personally use Meguiar's Gold Class.

Those $4 to $6 washes add up quick especially when you have multiple cars.

To answer OPs question, no, that soap dispenser is not what you're thinking and will not produce the foam like a foam gun. IMO foam guns are a gimmick and waste of soap anyway. For soap, get chemical guys, much better than mothers/meguiars.

The worst part with using a pressure wash is the waste of time to set up and put away. do yourself a favor and get a y-splitter, hose dedicated to the washer, and an extension hose for the washer. Mine now stays in one place in the back of the garage and I just have to turn it on and wash.

It's only 2 bolts to remove the hood cover. Then just drive it through the car wash and then take it on the 401 to air dry. Sparkling clean engine bay in 10 minutes.

Youre a genious. I never even thought of such a thing.
There are times that I am lazy enough to not want to setup the power washer that i will drive to a coin op and wash it there instead.

That only works for electric washers, which rarely last over 3 years even when you store them inside over winter.

Got tired of that several years ago and got a gas one. It's a little more pain to setup, but electric one just doesn't compare.

True. I only subscribe to one car wash in the pool when two cars may be needing washes. I am too frugal to spend another $4-5 on another vehicle. I will just hose them the doors down with plain water and use a peanut foam so that our clothes don't get dirty. One car doesn't need any pampering at all except some vacuuming as I don't want to be inhaling dust lol.

I'm not a car person. I just make sure all the sap and bird droppings get removed asap. I bought the car so they can be at my service, not the other way around.
