Urine Stains

Urine Stains

Urine is a problem that we professional carpet cleaners encounter on a regular basis. Whether the source is human or from any animals such as cats and dogs etc. etc. the problems are always the same. Unsightly stain, mal-odours and hygiene issues.  In every case, it is vital that the correct course of action is taken.

DO NOT apply any water or cleaning solution.

To minimise the risk of a permanent stain, it is vital to take immediate action. Using towels and cloths, absorb all of the liquid. For a more detailed explanation of this procedure, see my item “Spillage First Aid” below in the Spots and Spills category.

During decomposition, urine can convert from an acid to an alkaline, creating ammonia in the process. It is important that the correct procedure is followed, otherwise the chemical reaction can create a permanent stain.

Once you are satisfied that the carpet is as dry as possible, you can firstly treat the stain to try to prevent any colour change. Mix distilled (white) vinegar at between 1:10  and 1:5 with cold water. For a pint of liquid, add a teaspoon of Woolsafe carpet shampoo. Test this solution for colour or yarn damage on an out of sight area of the carpet. Apply enough of the solution to wet out the pile. Leave to soak for a few minutes for a fresh stain, then absorb out with towels and cloths followed by paper kitchen towels, until totally dry. Repeat if necessary.

For older, dried in stains, the procedure is the same but repeated a few times without any dwell time for the soak. Only on the final cycle would you leave the solution to soak.

For smallish fresh stains, this may be all the attention required. The acidity of the vinegar has a mild sterilising effect on the soil and will usually prevent the yellow/orange staining associated with urine.

If an anti- bacterial action is required, it may be possible to treat the affected area with a household anti-bacterial kitchen spray. The label on the bottle will probably instruct you not to use it on fabric or carpets, so care must be taken. Test this solution for colour or texture damage on an out of sight area of carpet. Remove any traces of the vinegar solution used as above by treating the affected area with plain water and absorbing with towels in the usual way.  Now spray the affected area sufficiently to wet out the pile, leave to dwell for 5 minutes then absorb out with towels as described above.

For any major stains that have penetrated the carpet’s foundation or backing, the carpet itself may need to be lifted and the backing be treated in a similar way. The local area of underlay may require replacement and even the floor may require treatment. This is typically a job for a carpet restoration specialist.

Never rub or scrub the carpet as this has little benefit and may well cause irrepairable damage.
