This is from an earlier post re my methods of cleaning harps:-
If wooden comb ie like Marine Bands ignore. But for Suzuki Harpmasters, Bluesmasters, Promasters, Lee Oskars & Sp20s I clean as follows , and have done for years:-
-Strip apart being careful to ID the reed plates with a permanent marker so that you can put them back without being upside down & back to front.
-Use a denture cleansing tablet in a tumbler of warm water & soak reed plates for eg 15 min. Steradent make a denture tablet that is ok to use with metals.
-Use dishwashing liquid + an old toothbrush to cleanse the comb and cover plates.
-Rinse off all parts in clean water.
-Hang out to dry in a shady area. I use bent paper clips to hold the parts.
When dry re assemble being carefull not to overtighten any of the screws ie don’t tighten one and then another but do tighten them all gradually. If you overtighten you may strip the thread or have a harp that leaks air.
This method of cleaning I have found restores the harp to ‘as new’. Minute gunk is removed from the reeds and plates that was dulling the sound. Harps sound better.
If you realised what was in saliva you will know that the above process can Wink do no harm. But don’t try it on a wooden harp.
Always carry your harps in a case otherwise fluff /lint will get into the reeds. I carry some harps in leather pouches but the original box gives best protection.
From a pharmacy I get Webcol Alcohol Wipes & use these to wipe over the mouthpiece. These wipes are cheap and are what the doctor uses to wipe your skin before giving you a needle. The wipes steralise the harp.
I always, before playing my harps :- 1) preferably brush my teeth or 2) use dental floss (I carry some in my harp case) 3) have a glass of water…but I carry a low cost, but good harp (Suzuki Folkmaster) which I use if I am having a beer & something to nibble.
