What is the best oven cleaner to buy to clean stuck aluminum off and old Nickasil cylinder I have? I read somewhere to get the cheap stuff because it worked better. Well, I bought some cheap crap from Walmart, tried leaving it for a few hours at a time and eventually over night while I slept and it barely removed anything.  I need to know what to buy because this cylinder is definitely worth saving. Thanks guys |

190mech has mentioned dollar store oven cleaner working for him. Gimme a minute and I'll see if I can find a quote. EDIT : Here ya go : May require a few applications of Easyoff,the cheaper Dollar General off brand oven cleaner has been doing a better job for me lately... Go to Dollar General and buy their store brand cheap oven cleaner,spray some in a cup and brush it thickly on the aluminum scuff area,dont get carried away with is as it does eat aluminum..Let it sit a few hours and scuff the deposit off with a ScotchBrite pad,reapply oven cleaner as needed,you'll know if its thru the Nikasil on the first application.

Muriatic acid is the ticket.Get a long wooden tip at the pharmacy and scrub the aliminum it will clean it right off.Get some thick rubber gloves work in a well ventilated area.When the cylinder is clean flush the hell out of it with water,blow dry with compressed air and hand home cylinder with 300 grit.I liberally apply WD 40 when done.Do not use a liberal amt of the acid and don't let it sit long.Thats a wooden qtip .Store excess away from metal I.e. tools etc.Causes rust.

Looks like you have an alloy cylinder might be safer to stick with the oven cleaner.

Looks like you have an alloy cylinder might be safer to stick with the oven cleaner. I saw another thread where someone else had used the muriatic acid on nikasil, didn't suggest it, but said it worked. If the another round of oven cleaner doesn't work then I'll try the acid. |

That was probably me that you saw using the muriatic acid. I used it on a nikasil Airsal cylinder that had streaks of aluminum from the piston. I watched it bubble away at the aluminum but didn't seem to react at all with the nikasil. It was a "free" cylinder out of a flip scoot so I didn't have much to lose. That cylinder ended up running real strong in a bugeye Zuma!

If you use the muratic acid have a mixture of baking soda and water handy for any spills.

I personally would use Muriatic but I hate to suggest it to someone who has never used it.It will clean the aluminum off almost immediately but it doesn't discriminate.if you dropped the cylinder in a pail of the stuff within ah hr you'd have some sludge and the sleeve.

Likewise if you do it over concrete you will have some really clean concrete. It's safe to use if your careful.

Muriatic acid is the old name for Hydrochloric acid. It is very dangerous if misused. Always add acid to water to dilute it. Never add water to acid. Never ever mix it with bleach. Be very careful, wear protective clothing, goggles and a face shield. If it makes contact with you either by liquid or fumes flush with large amounts of water. If the fumes hit your eyes you will not be able to see to get to water, so know where the water is by feel.
Oven cleaner is usually sodium hydroxide or similar caustic agents, just like most drain cleaners. They are the opposite of acids.
