A Rudraksha is woody plant tissue. Treated like the seed it is — kept dry, lightly oiled, out of heat and chemicals — it lasts for generations; family malas a century old are not unusual. Treated like a stone — soaked, scrubbed, left in the sun, washed with detergent — it cracks, fades, splits and decays. The rules are few and follow from what the bead is.
What damages a Rudraksha
Water, especially prolonged. Swells the tissue, opens cracks, washes out oil, and can start mould inside the chambers if the bead is not dried thoroughly. A brief rinse does no harm; soaking overnight does.
Heat and sun. Dries the bead too fast and too far; cracks follow. A bead left on a car dashboard or by a heater ages years in a day.
Soap, detergent and chemicals. Strip oil and can stain. Perfume, hairspray and cosmetics leave residues in the grooves.
Sweat, if never cleaned. Salt and oils accumulate in the grooves and darken them unevenly. Regular wiping prevents this.
Tight stringing and knocks. A tightly strung mala stresses beads against each other; a cracked bead struck on a hard surface splits.
Mould. From damp storage, especially in humid seasons. Shows as white or grey fuzz in the grooves.
Routine cleaning
After wear. Wipe with a soft dry cloth.
Periodically (monthly for a daily-worn mala, less often otherwise): brush the grooves gently with a soft toothbrush, dry, to lift dust and residue. If residue is stubborn, dampen the brush very slightly with water, work quickly, and dry the beads immediately with a cloth and then in air, out of the sun, for a few hours.
Never use ultrasonic cleaners, steam, detergent, alcohol, vinegar or lemon juice.
Oiling
Light oiling keeps the tissue supple and prevents drying cracks. A few drops of a neutral oil — sesame, mustard, coconut, or a light mineral oil — rubbed over the beads with the fingers or a cloth, then wiped off after a few minutes, every few months, is enough. The bead should not be saturated or left greasy; heavy oiling attracts dust, adds weight, and complicates examination.
Note that oiling darkens the bead over time. This is normal and is why old malas are dark.
Storage
In a cloth pouch or a wooden box, in a dry place at room temperature, away from direct sun. Not in an airtight plastic bag in a humid climate — trapped moisture invites mould. Not in a hot loft or a damp cellar. A small sachet of silica gel in the storage box helps in the monsoon.
Handling cracked beads
Fine drying cracks are normal and are stabilised by oiling. A structural crack — one that runs through a wall or around a pole — is a weakness; the bead can be worn but should be strung loosely and kept from knocks, or retired. Do not fill cracks with glue: the repair shows on examination and may be mistaken for tampering. Wormholes, cracks and natural flaws.
Re-stringing
Thread wears. A mala worn daily should be checked every few months for fraying at the knots and re-strung before it breaks. Re-stringing a mala.
Ritual cleaning
Many traditions prescribe washing a Rudraksha in water, milk or Ganga jal at certain times. The laboratory takes no position on the practice; from the bead's point of view a brief immersion followed by thorough drying is harmless, and prolonged soaking is not. Milk residue should be rinsed off and the bead dried, or it will sour in the grooves.
Frequently asked questions
How often should I oil my Rudraksha?
Every two to three months for a worn mala; less for a stored one. Lightly.
My mala has gone very dark. Is something wrong?
Darkening with oil and wear is normal and expected. Uneven black patches in the grooves are residue and should be brushed out.
Can I wear my Rudraksha in the shower?
Occasional brief wetting does no harm if dried afterwards. Daily soaking in hot water and soap will damage it over time.
There is white fuzz in the grooves. What is it?
Mould from damp storage. Brush it out dry, wipe with a cloth barely dampened with water, dry thoroughly, oil lightly, and store somewhere drier.
Does cleaning affect a laboratory report?
No. Cleaning and light oiling change nothing about identity. Heavy oiling adds weight, which can shift a match by a few hundredths of a gram.
