RO - bracelet cleaning and maintenance

[chuey38]

i note from some forums that dirt etc can be a key contributor to bracelet loosening over time rather than any tensile loads.

that said i note that on the RO bracelet, the gaps between then links gather dust relatively easily.

what do people find works well to get between the grooves?
is pressurised air in a can spray safe?
or a very light brush like the ones to apply shaving foam!
a microfibre cloth doesnt really get in between properly

or are there proper watch cleaning kits i shd consider?

i saw some ultrasonic cleaners (for bracelet only, not the head), but probably will stick to something simpler for now.

thx again
