Grate door won't open

I put in the number 3822 and the grate door won't open - help.

Did you get the monster out yet?

Use the pot filled with acid on the junk piled in front of the cabinet. Then you can open the grate.

I have tried filling the pot with acid, but it isn't working.....what am I doing wrong?

I have tried filling the pot with acid and it keeps saying it is putting holes in it so I must be doing something terribly wrong, someone help please.

You have to put sleelve in bucket yo keep acid in it. I recommend you google ghostinthesheetwalkthrough for BIG TIME HELP. I bought this game over a year ago and gave up on it until yesterday when I read blog recommending the walkthrough and now I am playing this game and really making progress! GOOD LUCK

I used 3822 and it doesnt work help. I did the pot and a hole oped up buy i am stuck

Thanks for the tip and for replying. I will try the ghostinthesheetwalkthrough. I was ready to give up too.
