Here is tip No. 1 regarding spots and spills on your carpeting: Clean them immediately. If you catch the spill when it is brand new, you’ve got a good chance of removing it totally. Consider these tips, too:
Carefully blot or scrape the entire area before applying any cleaning solution. Remove as much of the spill as possible.
Before using any carpet cleaning solution, test your carpet in an less visible to make sure the cleaner won’t damage or discolor it. Test the cleaning agents that you keep on hand before you have to use them to make sure they will not harm your carpet.
Do not rub spot or spills, that might spread the problem to a larger area.
When you apply your spot cleaner, work from the outside of the stain toward the inside to avoid spreading the stain. After applying a cleaning solution, blot up all the moisture.
A clean white bath towel is unsurpassed for drying carpet and brushing the nap back up to a standing position.
If you feel that there is still too much moisture after blotting the carpet, place a half inch thick stack of white towels over the spot and weigh them down with something heavy.
