    Tips on cleaning/polishing titanium MRG?

    Hello all,

    I have a used MRG-1100 that has signs of wear and looks a little tarnished.

    What Can I use to clean the watch and strap while still leaving the brushed finish intact?

    Any help would be great.

    Cheers,

    Catch.

    One of those green and yellow pot scourers. Needs to be done carefully though. You might find some hints by searching (all of WUS) for 'Scotch-Brite'.
    I used to list my watches here until I realised it ruined people's Google searches...

    Ah, good idea. I will probably try a less invasive treatment first but that will probably restore the brushed finish.

    Thanks for that.

    I've used a Scotch-Brite type product before. It works very well.

    My mrg-100T had the same problem , but I decided to give it a polished titanium look on the band and leave it matt on the face, the end result is very nice,the contrast really makes the watch stand out ! I will add some pics leater !

    Scotchbrite pads can make for a brushed look but titanium is a lot softer than steel so test accordingly.

    You can also use steelwool 0000 being milder than 00. You can use oil with scotchbrite and steelwool.


    If you want to do more detail, try the compounds(jeweller's rouge, general blue, etc)

    Re: Tips on cleaning/polishing titanium MRG?

    it depends on the alloy of titanium. Titanium has a better strength to weight ratio than stainless steel. if they're both the same weight, titanium is stronger. if they're both the same volume, then steel is stronger. if I have 2 feet of 2x4 stainless steel and 2 feet of 2x4 titanium alloy, then the stainless steel is stronger. However, if i matched the titanium alloy's weight with the stainless steel, the titanium alloy would be stronger, but it would no longer be at it's original size. It would no longer be 2x4, it would probably have to be 6x6 or much more if I were to keep it at the same length.

    Sometimes:

    "The surface hardness of gold, platinum, and steel varies greatly depending on how these metals were treated (annealed, rolled, etc.) and on other metal(s) used in the alloys. Commercially pure titanium (some impurities) is harder than some SS, but softer than others. The nitrogen-hardened surface of titanium (titanium nitride) is one of the hardest surfaces used in watches (Ventura), in addition to ceramics (Rado). The hardness of metals surfaces in the arbitrary MOHS scale (1 = hardness of Talc surface; 10 = hardness of Diamond surface) are, in increasing order: Aluminum = 2 to 2.9; Gold (pure) = 2.5 to 3 (typically 2.75); Silver (pure) = 2.5 to 4 (typically 3.25); Platinum (pure) = 4.3; Glass = 5 to 6; Titanium = 5 to 6 (strongly impurity dependent); SS = 5 to 8.5; Platinum-Iridium (950) = 6.5; Quartz = 7; Titanium nitride (TiN) = 9; Diamond (C) = 10
    In Brinell Hardness scale: Aluminum (99+) = 23-44; Gold (pure) = 28-48; Silver (99.9%+) = 30-90; Tantalum = 55-123; Platinum (commercial) = 65-101; Silver (sterling, 92.5%) = 65-125; Platinum (10% rhodium) = 79-169; Platinum (10% Iridium) = 104-169; Gold (white 18K) = 211-323; Titanium (commercial) = 200; Titanium (5 Al-2.5Sn) = 34 (RockwellC); SS = 160-400.
    Thermal conductivity (sq. ft x hr x ¡F/in.) A low number indicates slow heat transfer and a comfortable feel to the skin: Titanium (commercial) = 114; Titanium (5 Al-2.5Sn) = 54; SS = 96-400.
    Yield Strength (0.2% offset; 1000 psi) A high number indicates a strong metal: Titanium (commercial) = 75; Titanium (5 Al-2.5Sn) =120; SS = 30-165.
    Tensile Strength (1000 psi) A high number indicates a strong metal: Titanium (commercial) = 85; Titanium (5 Al-2.5Sn) =127; SS = 70-220."

    Windex removes crud and fingerprints from titanium.
