Product description

Oxalic acid is an organic acid sold in solid form as oxalic acid dihydrate. It can be applied in various ways such as for rust removal and cleaning of iron soils such as helmets, firearms, axes, knives, daggers, swords and cannonballs.

Oxalic acid is supplied in crystal form and is dissolved in water after. Because many ready-made products contain a lot of water and little deformation, we choose to supply only the oxalic acid crystals themselves. This not only saves on transport costs because no water needs to be moved, but it also allows you to easily create the strongest solution that can be made with these crystals.


Dissolve 100 grams of oxalic acid crystals in 1 litre of demineralized water. Hot water is quickest; for cold water, leave the solution to stand for a day and shake occasionally.

Contents: 500 grams

Storage: Keep cool, dry and out of reach of children.

Always work safely when cleaning and conserving soil finds. Wear protective gloves / protective clothing / eye protection / face protection
