stainless steel and should tolerate most clear bath formulations. Check
with the product manufacturer to be sure the product is safe for your
water bath.
• All of our water baths are fabricated entirely of commercial grade
acrylic. When using them with corrosive materials such as
hydrochloric acid or media containing salts, be sure to rinse them
thoroughly with deionized water immediately after each use, and
dry thoroughly with a soft towel or cloth.
• Do not clean with abrasive cleansers or cloths. Use deionized
water whenever possible. If you must use a cleanser or solvent, be
sure that it is as mild as possible, non-abrasive, and fully
compatible with PETG and acrylic before use. If in doubt, call the
service department for advice before proceeding.
• Do not use ammonia, window-cleaning sprays, kitchen scouring
compounds, or solvents such as acetone, gasoline, benzene,
alcohol, carbon tetrachloride, or lacquer thinner. These can
scratch the material's surface and / or weaken it causing small
surface cracks called "crazing".
• Our recommendations include but are not limited to the
following:
• Hot water:< 150 °F
• Vinegar (5% Glacial Acetic Acid)
• Ethyl alcohol: maximum 10%
• Isopropyl alcohol: maximum 25%

2 Remove the leaky bulkhead fitting.
3 Remove the elbow fitting from the bulkhead fitting.
4 Inspect the bulkhead fitting gaskets for damage and replace them as
