Quoted from Mbecker:I don’t know is novus is the best cleaner — but otaku is right that a lot of people DO use it, and personally if I use it 4 or 5 times a year I don’t think my games are gonna be devoid of clearcoat and down to barewood.. it just isn’t abrasive enough, esp with a little firm hand pressure.
Regarding naphtha being so dangerous to your health, read the msds again— it states No long term damage from inhalation just possible short term nervous system symptoms unless you have prolonged/long term exposure. Same for skin contact — dermatitis ie dry skin, same result as running alcohol . Sure if you would rather avoid possible dizziness or a sore throat, wear a mask better to be safe. But as for the great harm and danger this chemical poses, I don’t see it.
Novus 5 times every year
That is the only part in your statement that made me double take. If you used abrasive novus on an older machine and owned it 20 years, you would have lightly sanded it 100 times! Probably wouldn't have much left by then. The lightest of sanding 100 times on even a heavy clearcoat honestly still sounds like a LOT to me, but maybe not; I don't know since I have never done that.
I'm not saying I've never used magic eraser or Novus 2; I have, and it helped knock those spots on nasty playfields down when other items couldn't...but, I have also seen color on my rag (obviously especially with Melamine) when using on older machines.
I agree with the comments about every case is different, start with lightest and be more agressive as needed, etc. There is no cold hard answer for every machine type in every possible condition.
As far as the ENTIRE original point of this particular thread goes......well.....it has ABSOLUTELY NONE!
This threads point was telling people to use N2 over naphtha; which makes no sense what so ever since they are used for 2 different things.
Multiple times people already mentioned this, but it's like it didn't take for "some".
Before this thread, I never heard anybody make the statement about how bad naphtha was at removing dirt.
Simple...
Novus is an abrasive product that knocks down a small layer of the substrate (the use of this over many other methods wasn't the OPs topic).
VM & P Naphtha is a solvent (typically used in very small quantities) for removing various adhesives and as a quick wipe down to degrease prior to waxing/painting/clearing. I.E. NOT something slathered all over a machine to clean that dirt off with!
Safety/health hazard issues...well, certainly; most all chemicals have some. Solvent fumes aren't good! Dried compund dust inhaled is certainly not GOOD for you either. All work requires common sense and proper precautions and really shouldn't need explanation (unless of course a thread is specifically started asking, but then I would just answer with check MSDS). The comments about using indoors, what if someone sparked a game next to me, etc are just plain moronic to me. If it's cold in my garage, I wouldn't just take a part into my basement and spraypaint it against my furnace then complain I blew up....thats just Darwinian evolution at work.
Best product for the application and best safety practices. That simple
