Homemade hot tank?
 

Not really, but I'm just gonna soak the block in a tupperware bin because the local shop charges $50 for an acid bath, and the last block I took there I could still wipe oil/dirt off of it with my finger when they were done.

The question is, what's the best chemical to use?

Re: Homemade hot tank?
 

Purple power + pressure washer

Use a hose then ----------a, this is HMT! Not HMWIHPW!

tim used purple rush (commercial non------ version of purple power) on his block, took it to the carwash, and it looked like it was hot tanked.

I used said rubbermaid bin and soaked in purple power overnight. Gave it a good brushing with a nylon brush then hosed off. It came out good enough for me. I usually soak parts in silicone spray after drying to prevent rusting too.

car wash is local pwerwasher

Draino cleans the best, but wear gloves, and don't leave the block into very long.........it'll start eating the block also :)

TSP (Tri Sodium Phosphate) might work too.

i always liked oven cleaner, but you cant soak it in it. i just coat the block real nice and leave it for 10min or so then pressure wash. repeat

Yeah this was a 235k block fresh from the car complete with an inch of oily crud in some spots. It looks minty fresh now just make sure you wear a plastic garbage bag and maybe take a grinding shield cause my eyes burned for a couple days after.

how about muriatic acid? i use it to clean my saltwater fish supplies, diluted of course, but it rips apart calcium deposits. I know itll eat through paint also. so it may fuckup a rubbermaid bin.

but i know itll eat anything you want off a block. you can buy it in gallon jugs at Lowes for pretty cheap.

simply green works tits as well. i used it on my engine bay and motor and both looked good enough to eat off of. i need to do the engine bay again though.....its been about 3 1/2 years :P

I have a tub filled with many sad, sad chemicals. Purple power, simple green, some acetone and random other chemicals. Works pretty well :)

Re: Homemade hot tank?
 

Before I made this thread I tried using "Engine Brite" but it wasn't that great. I'm gonna try some purple ---- and bring my block to the semi truck bay at the local wash and pressure wash the ---- out of it :)

Re: Homemade hot tank?
 

i like using the dollar store oven cleaners. they are cheap and work pretty well. but i also have a pressure washer at home, so im set. yeah muriatic acid works good on some saltwater stuff, but not too much on my engine. also the bucket of random chemicals works eally good too.

Re: Homemade hot tank?
 

well i know muriatic acid will strip the paint right off a car.

either way, mix up some stupid ---- and see how it works lol.

purple power and hose 8)

Why not just use good ol DAWN soap. Apply it straight to the block. Let it sit over night. Scrub it again let it sit. Wash off with water and a scrub brush. Works great and then you can paint the block and have no worries of the saint peeling. We use Dawn at to wash down everything right before we paint. Including cars with two stage Dupont.

jago, bring it to my house and I'll break out the 3000psi pressure washer. No soap, no nothing. If you want, I'll put the red tip on and notch your block too.
