Hi everyone...I've looked all over the net for help on this, but nothing came up (except info on removing fungus from lenses...which isn't the case with me).
I bought two Prakticas...one is fully functional, but has spots of fungus on it and around the film-winding mechanism, a bit around the lens-fitting, etc. The other one is in perfect shape, but the light-meter doesn't seem to work.
So i guess my question is two-fold: How do i remove (permanently if possible) the fungus? And in the case where i can't do it myself, would it be cheaper to 1) remove the fungus 'professionally' 2) fix the light-meter on the other camera 3) buy a nother camera body.
Thanks in advance,
Andrei |

Do you mean that the chrome plating has spots of corrosion on it? Fungus does no grow on chrome plating. This type of corrosion is quite common on poorly plated or thinly plated parts.
You can remove the spots with a fibre glass contact cleaning brush. The use a very fine artists paint brush to place a small amount of an acidic toilet cleaner (one containing Hydrochloric Acid) on each spot, is another way. Note that the corrosion will have permanently damaged the surface of the metal component. However good model shops sell silver enamel paints that give a chrome effect. If the spots are very noticeable the use of this paint to disguise the corrosion spots does work.
Replacement Prakticas are very cheap, so do not pay to have these repaired. The non functioning meter may just be a corroded feed wire from the battery box. On the other hand if the rest of camera is OK, just use a hand held meter and forget about the internal meter.
I think there may be some details of cleaning chrome plate in the archive. |
