The real question is are you so vain that you believe everyone in God's creation owes you an explanation from the get go? You arrogant boob. >Why do people provide so little information when they ask a question? I look for a method for any darkroom plastic accessories. >What kind of tank?!!!!!!!!!!!!!!!!!!!!!!!!!!!

You may want to try some coffee-pot cleaner, followed by several washes. > Hello, > I've just bought a used tank.

Since you haven't gotten an actual answer: Hot water. Lots of it. If it's a stainless tank, leave the reel(s) in and pour in boiling water; put on the lid and cap and (using an oven mitt or similar protection from the heat) invert continuously for several minutes. If you want to be very thorough, replace the water with a fresh load fresh from the boil and do it again. This should remove anything that would come out in your photo chemicals. For plastic, don't use boiling water; if you have a means to measure temperature that high, use water at about 140 F; otherwise, mix boiling water with an equal volume of cold tap water, which should get you close. This should still pick up anything that might come out in room temperature photo chemicals, but won't be hot enough to damage the plastics used in the tank and reels. If there were visible junk on the tank or reel, a first wash with warm water, dish soap, and a Tuffy type plastic scrub pad (to avoid scratching) would loosen material that might be stuck on; follow with the hot water rinse as above.

Dish soap? Isn't it possible to contaminate chemicals? Thanks. .....................................

Isn't it possible to contaminate chemicals? No, because you rinse out the soap with water, leaving a clean tank with no contamination. Not rocket science exactly; more like basic dishwashing practice. SignatureEverybody's worried about stopping terrorism. Well, there's a really easy way: stop participating in it. - Noam Chomsky >>If there were visible junk on the tank or reel, a first wash with warm >>water, dish soap, and a Tuffy type plastic scrub pad (to avoid >>scratching) would loosen material that might be stuck on; follow with >>the hot water rinse as above. > > Dish soap? Isn't it possible to contaminate chemicals? Certainly, but the hot water rinse will remove all trace of dish soap -- one of the characteristics of dish detergents is that they must rinse cleanly off dishes, leaving no residue, and do it in water you can put your hands in. They also have to be mild enough not to harm skin. That combination makes them extremely useful in many other applications. SignatureI may be a scwewy wabbit, but I'm not going to Alcatwaz! -- E. J.
