Preparing to apply sound deadener: advice please

[Invid]

I'm about to embark on applying Resomat sound deadener to the floor/firewall of the TA22 and I was looking for some advice about surface preparation; mainly how to clean all the crap off the floor. I have stripped out the interior and carpets, and there is such a mess underneath (dirt, old glue residue, dust etc.). I have vacuumed the majority of the dirt up and scrubbed the floor, but when it dries it still leaves a dusty residuemess. Any advise how to get it squeaky clean. Tack cloths, or some other method?

Thanks in advance

Get the spray wax and grease remover and a scraper, just use an old towel to mop up excess wax n grease. Dry ice also helps remove the old deadener if you can get it. Oven cleaner also works if you're a cheapskate like me
