Konakoa, FWIW, see my working procedure below:

- Development wash / 1st (acid) clearing: 2 x 2 minutes in very mild (1 teaspoon per 2000ml water) citric acid solution.
- Gold toning: Gold-thiourea toner, half strength, 10 minutes.
- Fixing: 2% plain sodium thiosulfate, 2 minutes.
- 2nd (alkali) clearing: 1% tetrasodium EDTA + 1% sodium sulfite combined, 2 minutes.
- Wash: 5 changes of water, 7-8 minutes.

Probably overkill, but works extremely well for me.

Hope this helps,
Loris.
