How to clean the engraved numbers on a lens?

[carlostaiwan]

I bought a Nikon Fm2 and a 50mm, they are in good conditions, however the engraved characters like "Fm2" is super brownish. Same for the 50mm. I was thinking a toothpick and some rubbing alcohol. Any idea?

The set I bought:

with a toothpick a bit dumbed down

I would use denatured alcohol (rather than rubbing) a cotton swab first and then maybe very gently with a not very sharp toothpick.

for this kind of thing I find a toothbrush to be useful. IPA (isopropyl alcohol) is a good and safe cleaning agent

Very soft foam sponge and dampen with some dish washing liquid, do not use anything abrasive/scratchy or a fine sable hair (watercolours) brush with the soapy liquid.

Careful with toothpicks or such, the coloring can easily be scratched away like this.

I use a tootbrush soaked in warm soapy water. While i do this, i use a towel placed strategically in such a way that the water doesn't get inside the lens.

Of course, squeeze the tootbrush so it does not drip water...

Works perfectly.

it could just be dirty since the trigger finger is right there. try some soap n water on a paper towel. the engravings could also be worn or faded out.

sometimes people recolor old faded engravings with the laquer sticks sign shops use. but some of those old sticks used lead white n not titanium white. lead white yellows over time n appears as a goldenish color. in that case, just refill it n it will look brand new.

btw those laquer sticks are the same paint pencils used to fill nail heads for panelling from home depot.

Me too. Want a soft brush? use a child's.
Tooth picks may remove the paint. ^^^as above.

I once got a tube of eczema cream from the doctor and left it on the bathroom shelf....Guess what I cleaned my teeth with that night.

As for cleaning I would start with warm water and soft soap and then work your way up if that doesn't work......Tools cotton wool buds,paper towels,and toothbrush.

A toothpick lightly chewed will do no harm and I find them very effective.

...good news is it COULD have been Preparation H or Monistat vaginal antifungal

I've found an earbud with the end fluffed up a bit and moistened in isopropyl alcohol works well.

Toothpicks are too hard, they will scratch out the paint. A soft brush or cotton will isopropyl alcohol. Replacing or filling in the color is hard to get done correctly.

Soft toothbrush and soapy water. Wipe dry.
DO NOT USE TOOTHPICKS.
