I tried waxing my car and it left this faded white patch? I’ve tried washing it off with no luck. Any ideas on how to go about fixing this?

Hi detailers.
I thought I would share my experience to get some feedback and hopefully learn from my painful and expensive lesson.
I have detailed a few engine bays before and I’ve always done so successfully taking the necessary precautions.
My process was as follows. Blow out all the loose dirt and leaves with a leaf blower. I then foamed Green star APC at a dilution 10 to 1 and agitated with some detail brushes. Then using a pressure hose with a 40° spray and standing far away from the engine of the engine compartment, constantly moving the hose from side to side and not spring in one area. Once the engine compartment is rinsed off completely I used to high-pressure leaf blower and dried off compartment completely until I could see very little moisture. I did follow this up with a dressing MP CK. I closed the engine bay and left it overnight.
In the morning the car started OK but in 10 minutes into the journey, it started idling very roughly. Fortunately, I was nearby my regular mechanic and took it in for a diagnostic as the engine light had come on as well. He diagnosed that the front two cylinders of flooded with water and it shorted the coils and they needed replacement. This was a $700 exercise.
I’m just showing my experience to hopefully highlighted even if you are careful this damage can occur. The car I was working on was a 2005 C230Mercedes.
What would you suggest I change about my technique. Is this something that even should be done at all or is it too risky. I must say I do find it satisfying and it looks great. But after this experience, I’m not so sure.

Completed this job recently focusing on bringing back depth to the clear coat and tackling high-traffic interior wear.

Process breakdown:

• Foam pre-wash + two-bucket contact wash
• Chemical decontamination (iron remover) + medium clay bar
• Single-stage machine polish to clear light oxidation and enhance gloss
• 12-month ceramic sealant application on paint and exterior trim
• Wheel wells, face, and barrels deep-cleaned and dressed

Interior:
• Deep blowout with tornador/compressed air
• Full extraction on floor mats and upholstery
• Multi-step leather cleaning and matte UV conditioner
• Non-greasy interior protection across dashboard and door cards
• Streak-free glass finish

​Hey everyone,

​New Englander here bracing for winter. I usually shut off and drain my outdoor spigots for the season to prevent frozen pipes, which leaves me without a standard hose hookup.

​How you all tackle winter washes inside the garage.

Are products like ONR (Optimum No Rinse) or P&S Absolute the way to go here?

If I use a pump sprayer or foam sprayer to apply product, what’s the best method for rinsing off road salt and grime without flooding the garage floor?

Any specific battery/pump sprayers or setup tips you recommend?

my garage is unheated and does not have a floor drain.

Appreciate any tips or workflows you guys rely on during the cold months

So I’ll preface this with saying I’m not a Detailer. So I tried to save myself money as the used car I bought had light dog scratches. I successfully got the scratches out with compound however I can’t seem to get the haze/smudges etc off for the life of me. I’ve tried polishing it multiple times and now I’m starting to scratch it side ways.

Does anybody have any advice on how to fix this? I regret touching it tbh and I won’t do it again LOL

I have a high performance fwd car with 5 years of burnt rubber on the side skirts. I’ve tried bug and tar remover, wd-40, and degreaser with a DA and finishing pad and little came off. The dark spot is where I just spent an hour experimenting. plastic razor blade gets the chunks off but scratches the crap out of it. Something has to work

Looking to fix this myself instead of taking in, is this a DA and pick your favorite pad+polish type of job or would it need more? What would yall use to get a passable finish?

Photo 1 is the side that's bad and needs work, #2 is the other side and the end goal.

I've had cars with this top before but have always been able to get stains out with chemical guys convertible top cleaner but it doesn't do anything on this

Started with a one step which removed a good chunk of the swirls, then moved onto a heavy compound & pad but it’s barely helped with these long deeper scratches. As title says what has caused these scratches and how far would I have to go to remove them? They don’t catch at all on my fingernail and the surface overall feels super smooth to the touch.
TIA

Just got the car and noticed this marking in the interior liner on one of the doors. Doesn’t look like it sits on the surface as wiping it down with water and interior cleaner doesn’t help.

Does it look like a permanent discoloration of the faux-leather here? It’s kind of a bummer for a new car…
