How do you get gorilla glue off a carpet?

Answer 1

This is a polyurethane adhesive and very difficult to remove due to the strong covalent and cross-linked bonding of the adhesive.

Never use water, this will only catalyze the setting of the glue and make it all the more difficult to remove.

If the glue is still relatively wet, use several applications of acetone using a dry rag. Alcohol will work ok, though acetone is a much more effective.

Once the glue has set, i.e., it is dry, removal becomes very difficult. Heating to a high temperature helps soften the glue to a state where acetone can be used to slowly strip away the layers. However, this is not an acceptable choice when dealing with fragile surfaces.

From a solvent prospective, tetra-methyl ethylene glycol, methyl chloride, methyl nitrile worked best at breaking down the bonds to a state where removal was somewhat easier. Strong bases are also advisable, however there is serious caution that must be taken as the base could cause serious damage to the surface. Stronger bases are good for wood surfaces (pH 8.0 - 9.5), though the surface should be followed up with treatment using an mild acid such as acetic.

Lastly, polyurethanes are UV sensitive and the bonds breakdown upon being subjected to intense UV. Again though, this is not a readily available method. In the case of your carpet, I'm afraid you may be stuck with it.

In all and for all, removal of dried Gorilla Glue is near impossible without the use of mechanical methods. Solvents are only best if damage to the underlying surface is not a factor. Wood surfaces will work well with a stronger base which is what you're going to get in most of your over the counter stripping products.
