I bought and old blade but the original srivers are still on the blade.
the rubber and sponge are both so hard and frail that I can't get them off in a normal way. any ideas? |

Unfortunately there is no easy way. With rubber that is not brittle you could use lighter fluid to put in between blade and rubber to dilute the glue. But yours is brittle, possibly very well glued too (older glue), as such if you try to take the rubber off it will definitely break into pieces with sponge still stuck to blade. You have to slowly remove in numerous steps, remaining that wont come off you have to sandpaper.

Use a lot of acetone to try and dissolve the old glue. After that start - very carefully - pulling the rubber/sponge off the blade. Be prepared to spend a lot of time on that. As soon as some peeling off happens, pour more acetone in between sponge and blade. Etc, etc.
If at the end some remnants of sponge are left on the blade, use - with extreme caution - some sharp metal blade to slice them off or some very fine grade sandpaper to get rid of them. |

use this and acetone with time and patience. The wider the blade the better.

Use a RAZOR to cut/separate rubber from sponge, once you are left with sponge only you should be able to peel it of with your hand/fingers by pressing hard and trying to push/roll.
Worked for me :-) |

Stay away from the metal scraper if you can. Using acetone/Googone/cooking oil etc, softens the wood and any slip with the scraper causes wood damage. It's better to use the plastic scaper if you are new to this. The guys who do it all the time use metal ones.
Patience is the key. Oil a bit, wait a while, then scape a few mm, oil a bit,....and so on. This can take hours if it's a valuable blade. |

Acetone isn't aggressive enough. Chip away the topsheet to expose the sponge. I use ronsonol lighter fluid or naptha. Squirt it on to saturate the sponge. Wrap a plastic bag around it and leave it for 12 hours. It should peel right up.
probably not ideal for the blade but it works easily and I've not seen any damage

I just scrap and scratch away for an hour then sand, have a acetone (didn't do anything)
just did one with ancient rubbers , I get a few of them to do, actually some pre-mades especially yellow sponges are much harder

I removed two such rubbers from a racket recently, took me 3 hours and lot of sore fingers so be patient.

I have found using 3M scotch Kutchen cleaning pad (dry), the green side is very useful in removing old yellow sponge from wood, no use of any Acetone or oil, just DRY RUBBing and it does not hurt wood.

Chemical is the fastest but you have to let it dry out from the wood...reseal if you want.
I'm in the process myself but i decided the longer,messy way this time. First i use the razor: to get to this: after i'll use these sanding sponges to get to the wood: |
