Hi Adam.
I don't protect the transformers, the cleaning takes less than a minute and I don't deliberately aim the lance at components. The idea is to brush Traffic Film Remover on the chassis, leave it for a couple of minutes then quickly rinse with the pressure washer. The key is the drying process. I have a dehumidifier in the shed and an under bench heater. A small 1kw fan heater blows warm air over the full chassis and its usually dry within an hour. A compressor and an air blower gun is very useful too.
I've washed full colour TV printed boards that are covered in filth from cigarette smokers this way and have never had any issues. It's sensible drying, blowing the worst off with an airline and then a sustained warm air stream that dries the residue out.
My favourite TV was the first set I looked at as an apprentice in 1970, a Murphy V310 from 1958. My brilliant V310 is with a collector in Cramlington, I do have the V330 which has an FM radio inbuilt using the sets tuner, plus it is a double conversion superhet.
