Cheap enough to experiment with.
15% hydrochloric acid by weight.

Yes, take a close look at the label for "On and Off".

JimH prefers using abrasive powders.

Actually, in Jim's defense, he said that he did not rub out the stains
with Bar Keeper's Friend, just makes a paste of it and lets the acid
do the work. In my opinion that will not harm the finish although
something like "On and Off" or "Sno Bowl" will probably get the job
done quicker. All acids are potentially harmful to people or paint of
course. It makes no difference if they start out as a powder or a
liquid.

I always got a kick out of people who wear glasses and pay big bucks for
a "scratch resistant" coating on plastic lenses. The coating is actually
called a hydrophobic coating and does absolutely nothing to make the lens
surface "harder". All it does is adds a bit of lubricity to the surface
so dirt or dust will tend to slide off rather than scratch the plastic
surface.

Wiping them with mineral oil will do the same thing.

Eisboch
That sounds like me.
Would that mineral oil affect the UV coatings?


No. Wipe it on gently and then off gently.

If you paid for a "scratch resistant" coating, you were probably also given
a small bottle of "refresher" or something called similarly. Guess what's
in the little bottle?

(As I raise my hand) ME ME ME , Eisboch call on me.
Is that the same stuff my mother made me drink when I was a kid?
He didn't call you on yet.

****.

JohnH,
I hate to interupt this discussion of laxatives, but did you ever take
that photo class Nikon was offering? I took the D200 class Nikonian
Academy http://www.greaterphoto.com/ gave and it was a great course.

No, like a dummy, I didn't. I just looked and it doesn't look as though
Wash DC is on the agenda for next year.

I took the 18-200mm VR on the Disney trip. I don't know if I'm satisfied
with the sharpness of the lens. Actually, it doesn't make any difference
because I used it for about 450 pictures during the week. I'm thinking of
sending it to Nikon just to have them check it out.

"On and Off" works extremely well. It should, the main ingredient is
hydrochloric acid. It does not seem to harm fiberglass but it will
damage some kinds of paint and take wax off the hull. I wear rubber
gloves and glasses when I use it, wet everything down in advance, and
rinse well afterward. The best way to avoid slime build up is a good
coat of wax. Zud and Soft Scrub are two of the worst things you can
use on a fiberglass boat, try everything else first.

Best acid cleaners are the ones for toilets. Home Depot may carry them, but
janitorial supply stores do. Is a gel type version of muriatic acid.- Hide quoted text -

White kerosene? That's what I've heard: kero and mineral oil.

I could tell you, but then I'd have to ..... well, you know ...

Although it's been figured out (mainly due to the requirement for a Material
Safety Data report,
the official formula for WD-40 is still a deep, dark secret.

Hydrophobic interaction.

Yup. There is quite a science associated with this. We built high vacuum
processing systems that ionized gas (plasma) and bombarded the internal
walls of bottles -- plastic and glass -- with energetic ions. The process
super cleaned the surface and water would sheet, rather than bead.

Some well know beer companies use this technology.

Cool.

Thanks.

Something everybody should know, don't you think?

50% mineral spirits {dry cleaning solvent), 25% carbon dioxide for
propellant, 15% mineral oil, 10% inert ingredients.

He was simply providing some information. Does that call for the kind of

please provide it.
