Prep and technique is everything.
The secret to it is SNOW FOAM, it's power is not to be underestimated. In winter I snow foam twice and by the time that's been jet washed off the car is 70% clean before the 2/3 bucket wash commences.
If I lived anywhere near to you I would gladly accept the challenge of restoring your white goods to perfection.
The prep and technique was what I was getting at. Once a new car has been prepared as well as yours the dirt can't have too much to stick to!
Is snow foam really that good?
For years I've seen detailer show off their snow foam pics and I've always been very sceptical.
I've lost count of the amount of "miracle" products that I've seen come and go over the years with people almost forbidden to question them for fear of the wrath of the Internet! Snake oil and all that.
Once upon a time long before my hair gained its expensive silver tinge I had a part time job in a garage whilst I was at college studying electronics.
"Get a job in electronics boy, it's the future"
"It sounds boring" (and it was)
So off I went to seek my fortune in electronics only to find all the decent jobs had pissed off to the Far East by the time is taken my exams. Yeah, thanks oh sage like careers advisors.
Anyway, where was I? Oh yes.
In the garage we had a diesel powered heated pressure washer with seriously serious chemicals to use.
Even that (despite my boss's misguided claims) on full pelt didn't shift much road grime. In fact it could strip paint and chrome better then a layer of mud.
Henceforth I've always been a bit sceptical of snow foam.
Like DSG, I'd love to be convinced I was wrong.
