Bryan is right that Hel Gel performs well.
However, you may want to check the MSDS sheet.
One of the ingredients is kind of scary!
DICHLOROMETHANE...
(You might want to use it with extreme caution)
DICHLOROMETHANE MSDS:

-----------------------------------------------------------------------
EMS CATALOG NO: 19600
EMS PRODUCT: Dichloromethane
DATE: 05/15/95
PAGE NUMBER: One of 7
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Alcoholism, acute and chronic liver and kidney disease, chronic
lung disease, anemia, coronary disease or rhythm disorders of the
heart.
ACUTE TOXICITY:
INHALATION:
Major route of potential exposure. Methylene chloride depresses
the central nervous system. Concentrations between 900-1000 ppm
may cause dizziness. Nausea, headache, and vomiting can occur at
concentrations above 2000 ppm. At 7000 ppm, numbness and tingling
in arms and legs and rapid heartbeat have occurred.
Loss of consciousness
and death have occurred at levels above 9000 ppm, if exposure is prolonged.
Carboxyhemoglobin levels can be elevated in persons exposed to
methylene chloride and can cause a substantial stress on the cardiovascular
system. This elevation can be additive to the increase caused by
smoking and other carbon monoxide sources.
SKIN:
Liquid methylene chloride is painful and irritating if confined
to skin by gloves, clothing, etc. Prolonged or repeated contact
may cause irritation, defatting of skin, and dermatitis. Absorption
of liquid through intact skin is possible if contact with liquid
is prolonged.
EYES: Liquid may cause temporary irritation with temporary corneal
injury. Vapors may irritate eyes.
INGESTION:
Single dose toxicity low to moderate. If vomiting occurs, methylene
chloride can be aspirated into lungs, which can cause chemical pneumonia
and systemic effects.
FIRST AID:
INHALATION: Remove to fresh air. If breathing has stopped, administer
artificial respiration. Call a physician.
SKIN: Remove contaminated clothing and shoes. Wash exposed area
thoroughly with large quantities of water, for at least 15 minutes.
Wash contaminated clothing before reuse.
EYES: Flush eyes immediately with water for at least 15 minutes.
If irritation persists, call a physician.
INGESTION: Do not induce vomiting. Contact physician or emergency
medical facility immediately.
NOTE TO PHYSICIAN: Adrenaline should never be given to person overexposed
to methylene chloride.
CHRONIC TOXICITY:
The finding of chronic toxic effects in laboratory animals may
indicate toxicity to humans. Overexposure should be avoided, failure
to do so could result in injury, illness or even death.
Chronic overexposures to methylene chloride have caused liver and
kidney toxic effects in experimental animals.
CARCINOGENICITY:
Methylene chloride has been evaluated for possible cancer causing
effects in laboratory animals. Inhalation studies at concen-
trations of 2000 to 4000 ppm increased the incidence of malignant
liver and lung tumors in mice. Three inhalation studies of rats
have shown increased incidence of benign mammary gland tumors in
female rats at concentrations of 500 ppm and above and increases
in benign mammary gland tumors in males at concentrations of 1500
ppm and above.
Rats exposed to 50 and 200 ppm via inhalation showed
no increased incidence of tumors. Mice and rats exposed by ingestion
at levels up to 250 mg/kg/day lifetime and hamsters exposed via
inhalation to concentrations up to 3500 ppm lifetime did not show
an increased incidence of tumors.
The International Agency for Research on Cancer (IARC) has concluded
that there is sufficient evidence for the carcinogenicity of methylene
chloride to experimental animals, and inadequate evidence for the
carcinogenicity of methylene chloride to humans, resulting in a
classification as a 2B animal carcinogen. The NTP has identified
methylene chloride as an animal carcinogen, but it is not on the
OSHA or NTP lists as of September 30, 1988.
Epidemiology studies of 751 humans chronically exposed to methylene
chloride in the workplace of which 252 were exposed for a minimum
of 20 years did not demonstrate any increase in deaths caused by
cancer or cardiac problems. A second study of 2227 workers confirmed
these results.
REPRODUCTIVE TOXICITY:
Reproductive toxicity tests have been conducted to evaluate the
adverse effects methylene chloride may have on reproduction and
offspring of laboratory animals. The results indicate that methylene
chloride does not cause birth defects in laboratory animals.

PERSONAL PROTECTION AND CONTROLS
________________________________________________________________
RESPIRATORY PROTECTION:
Where vapor concentration exceeds or is likely to exceed 50 ppm,
an approved full face respirator with organic vapor canister is
acceptable. Approved self-contained breathing apparatus or air
line respirator, with full facepiece, is required for vapor concentrations
above 1000 ppm and for spills and/or emergencies. Follow any applicable
respirator use standards and regulations.
VENTILATION:
Do not use in closed or confined space. Open doors and/or windows.
Use ventilation to maintain exposure levels below 50 ppm (TWA).
SKIN PROTECTION:
Wear solvent-resistant gloves such as Viton, polyvinyl alcohol,
or equivalent. Solvent-resistant boots, apron, headgear and/or
faceshield should be worn where splashing is possible.
EYE PROTECTION:
Wear safety glasses. Contact lenses should not be worn. Chemical
goggles and/or face shields should be worn where splashing is possible.
HYGIENE:
Avoid contact with skin and avoid breathing vapors. Do not eat,
drink, or smoke in work area. Wash hands prior to eating, drinking,
or using restroom. Any clothing or shoes which become contaminated
with methylene chloride should be removed immediately and thoroughly
laundered before wearing again.
OTHER CONTROL MEASURES:
To determine exposure level(s), monitoring should be performed
regularly. Safety shower and eyewash station should be available.
NOTE:
Protective equipment and clothing should be selected, used, and
maintained according to applicable standards and regulations. For
further information, contact the clothing or equipment manufacturer.

STORAGE AND HANDLING PRECAUTIONS
________________________________________________________________
Follow protective controls set forth in Previous Section when
handling this product.
Store labeled, sealed containers in a cool, dry, well-ventilated
area out of sunlight. Prevent water or moist air from entering
storage tanks or containers. Do not cut or weld on empty or full
drums. Aluminum equipment should not be used for storage and/or
transfer. Contact with aluminum parts in a pressurizable fluid
system may cause violent reactions. Consult equipment supplier
for further information.
Vapors are heavier than air and will collect in low areas. Do
not enter confined spaces such as tanks or pits without following
proper entry procedures such as ASTM D-4276. Do not remove or deface
label. Do not reuse drum without recycling or reconditioning in
accordance with any applicable federal, state or local laws.

SPILL, LEAK AND DISPOSAL PRACTICES
________________________________________________________________
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
Evacuate the area, ventilate, and avoid breathing vapors. Dike
area to contain spill. Clean up area (wear protective equipment)
by mopping or with absorbent material and place in closed containers
for disposal. Avoid contamination of ground and
surface waters. Do not flush to sewer.
If spill occurs indoors, turn off air conditioning and/or heating
system, to prevent vapors from contaminating entire building.
WASTE DISPOSAL METHOD:
Recovered liquids may be sent to a licensed reclaimer or incineration
facility. Contaminated material must be disposed of in a permitted
waste management facility. Consult Federal, State, or local disposal
authorities for approved procedures.
