Mumble By Design highly recommends the use of TensorGrip C101 to clean surfaces before installing acoustic panels and to clean any excess TensorGrip x40 that may be sprayed when installing. TensorGrip® C101 Citrus Cleaner is a biodegradable, citrus solvent cleaner, degreaser and adhesive remover. It can be used safely on most surfaces and substrates, including painted surfaces, glass, porcelain, concrete, and is compatible with many plastics and vinyls. This product only ships to NSW. Also available in a 500ml Aerosol.
