For removing all types of paints, varnishes, resins, and most other organic coatings including those with high resistance to chemicals such as baked epoxies and certain isocyanates. For removing carbon deposits, as from DETACHED carburetors and similar metal objects.
Apply by methods shown. Keep surface wet until coating is removed, or liquefied, or wrinkled. Time required may be as little as 5 minutes, rarely more than 30 minutes. Some products can be used hot as heat increases effectiveness and reduces time needed. Remove any residue with stiff brush or scraper or steel wool, or by rinsing with water or suitable solvent such as mineral spirits or turpentine, or by any combination of methods that are needed. If water is used, hotter is better, a suitable detergent may improve performance and a pressure washer or steam cleaner may help. To prevent rust on iron and steel, hot water improves evaporation. For assured rust prevention use hot water and a combination detergent/rust preventive like Metalterj #1520, page B1, or a suitable Rust Inhibitors, page B7. Products shown below with "ammonia odor" contain ammonia. Ammonia helps removal and its odor is a built-in warning against inhalation.
Cardisolvs
Removers called "Cardisolvs" are harmless to all metals and stone-like materials such as concrete and ceramics. Wood is usually slightly fuzzy after paint is removed, especially if water-rinsed. To minimize sanding, use as little water as possible. These products are harmful to most plastics; test before using on plastics and apparent wood veneers -- some apparent wood veneers -- some apparent veneers are plastic. THICK LIQUIDS -- For Use By Paint-On -- These Products Cling To Vertical Surfaces
Cardisolv #6812
Use cold. Use full strength. An effective product for removing the raw components of coatings by the paint-on method. Intended as a pre-solv or for dry coatings. Almost colorless, translucent, no flash point, poison, ammonia odor; details on request.
Cardisolv #MCE
Use cold. Use full strength. An effective product for removing dry coatings by paint-on. Almost colorless, translucent, no flash point, poison, ammonia odor; details on request.
Superblend Plus
Use cold. Use full strength. An effective product for removing the raw components of coatings by paint-on. Intended as a pre-solv or for dry coatings. Contains no chlorinated solvents, alcohols, or ammonia. Colorless, flash point 150F, pleasant odor; details on request.
THIN LIQUIDS -- For Use By Immersion Or Recirculation Or Vaporization
Cardisolv #681
Use cold. Use full strength. Usually the most effective product for removal by immersion or recirculation. Use a covered tank to retard evaporation; do NOT use a water seal. Low viscosity permits quick run-off which reduces drag-out losses. Pale amber, no flash point, poison, ammonia odor; details on request.
Cardisolv #DP3
Use cold. Use full strength. Less effective than #6813 for most applications, but when the job requires that vaporization method be used, #DP3 may be better. If used by immersion, use a covered tank or 3" water seal to retard evaporation. If used by recirculation, use a covered tank if possible to retard evaporation or provide ample ventilation. If used by vaporization, a closed tank is essential to contain vapor. Blue, no flash point, does not require poison label, TLV 300 ppm, characteristic solvent odor; details on request.
THIN LIQUID -- For Use By Immersion Or Recirculation
Cardisolv #MBA
Use cold or hot. Use full strength. Use #MBAO only when other removers have proved ineffective -- #MBAO is very expensive. Use hot if necessary, up to 190F. Evaporation is not a problem. Colorless, flash point 199F, boil point 395F, TLV is above vapor saturation point, evaporates slower than water; details on request.
Stripper #5250
Use cold or hot. Use full strength. Harmless to steel, stainless steel, and stone-like materials such as concrete and ceramics. DO NOT USE ON ALUMINUM. Test before using on other soft metals or on any surface that might be harmed by strong alkali.
Superblend
Use cold or hot. Use full strength. Use hot, if necessary, to 140F. Evaporation is not a problem. Colorless, flash point 150F, boil point 336F, evaporates slower than water; details on request.

In general:
Solvents are usually harmless to metals, wood and stone-like surfaces such as concrete and ceramics. Solvents may harm plastics.
Depending on the metal, a suitable detergent can be chosen which will not harm the metal. Detergents are usually harmless to plastics and stone-like surfaces; detergents usually damage wood; detergents may separate veneers.
Immersion or recirculation is faster than paint-on or vaporization.
