If you have a heavy equipment mechanic in the family or someone who operates large machinery, they may track hydraulic oil onto your carpet. Hydraulic oil is used in large equipment such as bulldozers and backhoes to grease the hydraulic parts and keep them working properly. The oil leaves a greasy stain on carpets and requires immediate removal to prevent permanent staining.
Apply a citrus-based solvent to a rag. Blot the solvent onto the hydraulic oil stain, working from the edge of the stain toward the centre. Continue blotting the stain until the oil no longer transfers to the rag.
Mix 1/4 tsp dishwashing soap with 1 cup water in a bowl. Wet a clean, white rag with the cleaning solution.
Blot the remaining hydraulic oil stain with the rag. Turn the rag to expose a clean area as the stain transfers to the rag. As the rag becomes saturated with the oil, replace it with a new one. Continue blotting the stain until completely removed from the carpet.
Wet a clean cloth with cool water and wipe over the affected area of the carpet, removing the detergent. As the detergent lifts from the carpet, rinse the cloth and continue blotting, removing all soap residue.
Press towels into the carpet to remove excess liquid. Leave the towels on the wet area and place heavy books on top to help speed up the absorption. Replace towels as they become saturated with liquid.
- Do not scrub or use a brush when removing hydraulic oil stains, as doing so only pushes the stain deeper into carpet fibres.
