    Seeing as I bought into the argument that you shouldn't use Novus2 for regular cleaning and many people recommend Naptha which is flammable I was wondering if isopropyl alcohol could be used instead? This would be for modern Bally/Williams and Stern DMD games?

    is Naphta better at cleaning? Or safer on the playfield?

    Thanks.

    #2 4 months ago

    Alcohol leaves residue behind, and can sometimes stain wood.

    Lots of things are flammable. Heck, pins can start electrical fires. Just don't use naphtha near an open flame or while smoking a cigar, and you'll be fine.

    #3 4 months ago

    I've used isopropyl for years on modern games no issue. Recently switched to novus 2.

    Key is 99% only not 91%

    #4 4 months ago

    Are you trying to summon vid1900 ?

    #5 4 months ago

    I use 99% isopropyl for cleaning the underside of inserts so I would use the 99% stuff.

    Yes, guess I am trying to summon vid1900.

    I have no problem using Naptha just figured the alcohol is already in my tool chest and don't know why it wouldn't be a good choice.

    #6 4 months ago

    Where do you find the 99% stuff?

    Novus 2 is abrasive. Not a great idea to use just for regular cleaning.

    Anywhere. Walmart has it.

    It's very very very minor. You would have to clean with it thousands of times to notice it.
    Clay uses it on all of his games at VFW and they are all really nice.
    Here is my getaway before and after novus 2.

    My Walmart's can get 99% alcohol if I ask them to order it. There is no extra charge other than 99% costs a little more than 91%. It is just not a shelf item.

    My Kroger pharmacy has also ordered 99% in for me.

    The best I’ve found at Walmart is 91%. If they have 99% I would like to get it. Do you have to go to the Pharmacy counter to get the good stuff?

    #12 4 months ago

    I guess I posted a little too late.

    #13 4 months ago

    So you have to special order the 99% alcohol at Walmart?

    #14 4 months ago

    I use Novus periodically. It is a polish and works very well, even on EMs.

    Quoted from PBFan:

    That's a shame.

    #16 4 months ago

    I wouldn't advise using alcohol when cleaning early Bally solid states, in my case Space Invaders. The alcohol ate right into the lacquer topcoat, luckily I was testing it in a small spot covered by the apron so it'll never be seen. Naphtha (plus Magic Eraser for really ground-in grime) only from now on, then use Novus 2 to bring out the shine.

    Edit, just saw this thread is for newer B/W games, never mind!

    Quoted from kevmad:

    So you have to special order the 99% alcohol at Walmart?

    Just walk up to the pharmacy window and ask them to order you a bottle of 99%. It will be there in 1-2 days. There is nothing special about it. They may take your name and call you when it arrives.

    #18 4 months ago

    Alcohol will dissolve some clearcoats. Naptha wil not harm paint or clear. Naptha is excellent for removing old wax. Vaccum, naptha, Novus 2 if needed and then Blitz or other carnuba paste wax without silicone.

    Quoted from pinheadpierre:

    It will dissolve lacquer finishes that where put on older SS pins but, should not affect the newer CC on modern pins. Alcohol will dissolve latex paints but not enamels etc..

    MSDS on Naptha makes it seem a little harsh just for cleaning up a game. With so many other milder alternatives, why go with most toxic? I wouldn’t want those fumes in house or closed garage.

    I use novus 1 or simple green to clean playfields, the latter works well for more stubborn areas.

    It's amazing stuff and I don't mind the smell of it. Cleans rubbers, targets, metal ramps, wireforms, etc. Makes flippers with the typical black gunk on them look new.

    Ace hardware near me stocks 99% in gallon jugs

    #24 4 months ago
    Quoted from TheLaw:

    That's a shame.

    I do use Novus2 - just not very often anymore for "routine" cleaning. I have 12 pins at home and combined they don't get 2k games per year so they don't require Novus2. I do use Novus2 on every game that I purchase when I first take delivery of it but I no longer clean them twice per year with Novus2 like I used to.

    #25 4 months ago

    In Canada, I can find the 99% Isopropyl on the shelf at Rexall pharmacies. I can only find the 91% at Walmart.

    #26 4 months ago

    My slight preference to not using Naptha arises from the complaints I get from my family about the smell in the house (as ventilation is a bit of an issue). I use it all the time in the garage for cleaning parts. Hence why a milder solution is preferable.

    In the old days when working in the garage doing automotive repair engines I would not in-frequently use gasoline to wash my hands to remove the really stubborn worked in grease - other than the odd weird twitch I am fine. Not really a good idea but sometimes you just do what works best.

    My uncle was a farmer with all of the farm equipment. I saw him wash his hands with gas one day. This was the leaded gasoline. After that, I did that for just a few times. Gas is a great hand cleaner. But then I learned that the lead in gasoline could be absorbed into your body and I changed my ways.

    I use the 91% alcohol all the time but will switch to 99% now that I know how to get it. I would like to warn people however about at least one game that alcohol will totally wipe out the sideart with....Spiderman.

    I do not know which process they used on the sideart of it, or what other games have that process. But I started cleaning one around the area beneath a leg and it started taking the ink off immediately. Beware and pass this information on to your friends.

    Quoted from playernumber4:

    one game that alcohol will totally wipe out the sideart with....Spiderman.

    That paint must be latex based as alcohol will dissolve latex. I used to test swimming pools with alcohol when the owner didn't know what type paint was applied previously, latex or epoxy paint. If you can rub the paint with a wet cloth (alcohol) and come away with paint it's latex if not epoxy.

    Quoted from PBFan:

    in this case, the smell=toxins.

    Novus gets a "warning" on MSDS, Naptha a "Danger"...way higher % of toxic crap in naptha vs novus or alcohol or good ol fashioned elbow grease. Not worth it for a pinball game vs health of family--pets, kids are especially susceptible with growing brains.

    #31 4 months ago
    Quoted from PBFan:

    is Naphta better at cleaning? Or safer on the playfield?

    It would help most if you cited which playfield you wanted to clean.

    To be fair, there is no one "playfield", and thus there is no one single answer to the question.

    Here's how I'd break it down...

    1. pre-modern with no clear coat: naptha for sure
    2. pre-modern with mylar: 99% (anything is ok, but this is the strongest)
    3. modern or CPR with clear coat: novus 2 ???

    Do you agree with the 3 grouping and solutions? I'm not a chemist, but that's my feeling on it from listening to people.

    #32 4 months ago

    Oh ya, naptha wreaks. It doesnt cloud stuff though, and Ive had alcohol cloud before. Naptha has worked well for me so far.

    99 percent isn't all it's cracked up to be. It evaporates so fast it's difficult to use efficiently. So if you can't find 99 it's no big thing, 91 is fine.

    #36 4 months ago

    following. I'm about the clean the playfield on my first pin a 1974 CCM Dolphin. It is in bad need of a cleaning: I orded a bunch of parts from Marco Pinball including the NOVAS basic kit.

    Yeah alcohol wont be cleaning that, that's Novus country.

    #38 4 months ago

    Magic eraser and alcohol, just careful how aggressive your are and then follow it up with a good Novus cleaning and a Naphtha wipe down before wax.

    #39 4 months ago

    Been using simple green sparingly (spraying micro fiber first in a light myst then good ole elbow grease).

    Looks like it is cleaning up nicely.

    #41 4 months ago

    Alcohol will strip your clear coating, Naptha won't.
