340da blower moulding....cleaning

[jim_m5]

Not sure how to explain, but how do you clean the outside exterior moulding of the blower vents.? They are made of a hard plastic not gel coat. The plastic has some 'yellowing' on it and I want to whiten it up. Tried standard cleaners with no luck. Any tips?

I use 3M "Restorer & Wax" which seems to work well.

There's a limit to what you can accomplish. Yellowing is due to UV damage, it's not like dirt that can be cleaned off.

Short of replacement, you might consider a can of spray paint that's for plastics. I've had good success with it on other things, I bet it would work well for this application.
