I wanted to caution everyone about using aluminum with methylene chloride. I found this warning on the OSHA website:

Do not use aluminum in any equipment used to handle, store, or process MC. MC corrodes aluminum. If aluminum parts fail, spills will occur.

Not only did I read this warning, there were many sites that had information about the reaction of MC and aluminum and in many cases sources stated that the reaction of the two could cause corrosive acid fumes (especially in warmer temperatures) that could be potentially dangerous.

I understand that the aluminum pan is not meant to touch the poultice but if it would drip/fall onto the aluminum and react over a period of time it could be hazardous.

I recommend researching all chemicals before using them to understand possible reactions.

Anthony,

I use a stripper from Aldon Chemicals called Premium Stripper it comes in a jell like consistency and works well when making a poultice. You can probably find something similar locally. I use a disposable aluminum baking pan to cover the poultice. Inside the pan I use an absorbent roll and place it along the bottom, like the rolls used to contain a spill. Tape it to the wall and you should be good to go.

Agreed – this is a possibility- My issue is how to place it on the wall though- The solvent will work its way through the tape needed to hold the plastic on the wall

Anthony,

I think you may need to make a poultice using methylene chloride to remove the rest of the silicone. Mix up your poultice using DE powder and the Methylene Chlorides into a paste like you would any other poultice and cover the spot completely. Be sure to cover the poultice with plastic and make sure NO one gets into this poultice. Put some small holes into the plastics so the poultice and dry. Let the poultice work for at least 24 to 36 hour and then remove it . Clean the area using a neutral cleaner. Let the surface dry , this could take a day or two, with any luck when you return the stain will be gone.

Caution, if there are children, pets, or the area is open to the general public be sure to cover the poultice completely where no one can get into the poultice.

1- Does anyone know the name of this stone

2- I removed the excessive silicone, I grinded and honed and retextured the stone, but the silicone hue still exists. What would you do?
