Ultra Sonic Bath would be an option. Alternatively if the next TAG Heuer boutique or official dealer is not too far away from you, I'd recommend a visit. I wonder why the ball housings are not made of stainless steel.
You can ask this ebay seller. He offers the complete set lugs+titanium bracelet in this add, but I think you can buy just the lugs. I bought my black ceramic lugs, black ceramic bracelet, and titanium bracelet to him. Great seller! https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.es/ulk/itm/183605608807
Thanks. How much u bought the lug for? Was looking for cheaper alternative as i could get a Formula 1 watch instead of paying for the lug
I think I payed around 500€ for the black ceramic lugs (less than half the normal price), brand new but without box. Titanium lugs should cost a little less
