Hi guys

Just picked up a lid/dust cover for a Revox A77. As you would expect for its age about 30 to 40 years the lid is a bit marked. Does anyone know how to polish out such marks and what to use to do it ? This info would also be of use/benefit to those who have TT's with lids in a similar state.

I used to use brasso metal polish to remove scratches from a plastic watch face I had! That was recomended to me by a watch maker. It was very effective...

Brasso eh, new one on me I'll give that try.

My 1210s' biggest failing is the lid, cheap and nasty doesn't get close to describing it, every time a look at it the bloody thing has another mark on it:steam:. Anyway I tried some stuff from Halfords called "Fenwick's superior Windowize" which claims to be a 'scratch remover for plastic acrylic windows'.
Oh No It Isn't
They should have called this stuff 'Scratch 'n Haze' would have been much nearer the truth, seriously don't use it, it's crap.
If the Brasso don't work I'll take some wire wool to it and try and give it an artistic 'frosted' look.;)

No, don't do that. There are cleaners and polishes which are very effective, I've seen them used. Trouble is, I don't know what they are called but I'm certain that someone on here does.

DSJR where are you ?

hi neil,
if its acrylic and its quite badly scratched then use T cut for metal car paint finnishes, if its realy badly scratched then use the regular T cut first to get most out, then finnish off with the less abrasive metal car paint version.
hope this helps, and yes i have used this method many many times as the soul and soul-mate covers are all made from acrylic.
regards,anthony,TD...

To be honest I don't know what its made from. Its a cover for a Revox A77 R to R so its 1960's to 1970's don't know which :confused: It could be perspex but I doubt it. Anyone know ?

Hi Neil,

Just try Brasso (liquid) or either Brasso or Duraglit polishing wadding. BUT first try any of them on a small part of the lid/cover that doesn't show, just in case they are too aggressive. They ought not to be, but better safe than sorry. Well wetted toothpaste can also work, but again try out on a small area first.

Afterwards give a good polish with Mr Sheen.

I use "Novus Plastic Polish".

You can get it other places.

Good stuff, may take some work depending on the damage involved.

Duraglit polish wadding is a chemical treatment only. Not being abrasive it is unlikely to remove scratches from plastic. Brasso I would expect to be a bit course and leave a 'haze' although it might well work on a watch glass because of the glasses closeness to the face. It would be good to remove deaper scratches on an area later treated with a finer polish. Some people have had good results with toothpaste and the ultimate is considered to be Jewellers Rouge which I think is about the finest polish you can get.

The bottom line is, whatever the product, only superficial marks and scratches are likely to be successfully removed.

I think I may still have some jewelers rouge in my jewelery tool box(I did Jewelery design as a degree in Art college). I will have to have a look.

Thanks for the suggestion Greg.

Another vote for the Novus products.

They are recommended by Stillpoints in the States and some bottles were supplied with my Stillpoints equipment rack for polishing the acrylic shelves.

For deep scratches, use the #3 Heavy Scratch Remover first and then apply the #2 polisher and finish with the #1 spray which is also a very effective polish and anti-static cleaner.

I had forgotten about this thread.

In the end I decided not to do anything, as I did not know what material the lid was made from. I could make it worse than it is.
