My go to method for removing rosin from violin strings is to use a wine cork.  It must be popular, because Warchal tested it in their lab.  They found that cork particles embedded themselves in the string core and the winding can be damaged by this method.

The recommend that the strings be individually rubbed with a clean dry microfiber cloth to remove rosin.  Hardened material can be scrubbed clean with the edge of a credit card.  They offer microphoto images to prove their point.

Interesting @Irv  -I did once try the cork trick - I didn't like the "feel of it" although at the time I wouldn't have thought about the string acting as a "cheese grater" and getting cork into the string (but it makes sense) - I just didn't like how it worked. 

Before ( and since ) the cork experiment - I have used/still use a silk and also a micro-fiber cloth - and on occasion, I'll dampen it with ethanol ( well, methylated-spirits is what we get here - it's 95% ethanol, 5% methanol and a repulsive tasting purple dye to stop folks drinking it - (mostly!) )

If anyone does this ( using ethanol/methanol ) - DON'T SOAK THE CLOTH to the point of it dripping - and DON'T get it near the body !!!!  Take care - it just needs to be dampened...

For the record, I checked out the Warchal page Irv mentioned:

Billy, doesn't look like Mr. Warchal is a fan of using a solvent either and shows interesting pics to explain why.

I use a dry yellow cotton duster and a fingernail for the lumps. Please don't quote that out of context, lol!

Yup - I know ( @bocalholly ) - but I'm happy with it for my needs, and only use the alcohol dampened (not soaked) cloth on occasion ! 

Although - having said that (about not soaking the strings) - once or twice in the past - I've taken the strings off and shaken them in a jar of eth/meth-anol - it's not only the bow contact area that gets gunged-up with rosin - the fingered parts of the strings get all sorts of gunk on them from sweat, grease, skin micro particles and so on - I understand there can be a "danger" in affecting the inner core of wound synthetics - but certainly when I did that - these old strings (pretty much undamaged in any other way as far as the naked eye could tell - like at pinch-points on nut and bridge) - sang again - maybe not as well as broken-in-new - but significantly better than before the cleaning.  [ I only did that because I was sort of forced into it - I knew I would have to wait at least 4 days to get the new ones I had just ordered, delivered ]

Yup - it all depends on just how vigorous the approach is - like the cork thing - I just didn't like "how it felt" on the strings and felt "unsettled" when I tried it - so I resorted to the plain cloth - and of course occasionally the alcohol - when/if used - just damp and no more.  The full-on alcohol "bath" is desperate measures for an old, tired string set !  🙂 and is certainly not recommended on a regular basis !!!

Hey, me and my violin parts, we're no tea totalers either. Remember, I'm the girl who gives her bow hair an alcohol bath when in trouble. violin-bang

I usually use alcohol patches. I've got plenty of them. Works well and I don't need to scrub.

His alcohol test only showed that it penetrates to the fibers, not that it effects performance or longevity.

My strings usually last about 5-7 months before the windings on the D or A string starts to give out and by that time I figure they're due for replacement anyway.

I too have stripped rosin off of bow hairs with alcohol when I experiment with different rosins(only way to be sure that it's the rosin I'm experiencing I figure).

Good points. I'm on my first set of strings since I bought the violin at the start of October. I'll replace them when my teacher tells me to.

I think you should be warier with a natural fibre such as horse hair. Alcohol dissolves protein, and other chemicals will be potentially even worse (bleach will dissolve the hair completely).
