I've used the hair dryer/airing cupboard/sink of hot water method then put it under a huge pile of records - normally its reasonably successful but the record will never be perfect again. Also if its warped really badly even going over it with a steam roller won't do any good!
If you need to clean your records make a really strong solution of washing up liquid (so its still green), spray that on (avoiding labels) and leave for a couple of minutes; try to avoid rubbing with a cloth in case there is any dirt particles which will scratch your grooves... fill your bathroom sink up just to the level enough to avoid reaching the labels and rinse the record thoroughly. Do the other side and rinse again - if possible leave it soaking for an hour or so and rotate. Take it out and prop it up in the bath or somewhere similar vertically for about half an hour and let the water run off. If you want to be fancy you can then use an antistatic record spray available from good record stores (and a lot of wack ones too). If that doesn't do the trick the record is ***ed. If you have a scratched cd you can possibly recover it by rubbing toothpaste over the scratched area with a soft cloth for about 5 minutes. Your cd may end up tasting of mint but will sound like new again! BABY DIDDY
