Q: If there are a few stains that won't come off with regular cleaning, then you can try treating them with nail polish remover or rubbing alcohol. Rub the stain with a cloth that has been dipped in rubbing alcohol or nail polish remover. Always test the fabric before applying to stains to ensure that it does not leave a mark. In order to do this, you will need to apply baking soda to the stain and let it sit over night. The baking soda will absorb any grease from the leather. The next day, simply wipe the surface with a clean cloth. To do this, wipe off any loose dirt or dust, then wet your shoes using a damp cloth. Next, dab a small amount of toothpaste onto your shoes and rub in using your fingers. Pay close attention to any stains or scuff marks. Scrub any tough stains with an old toothbrush. Then, wipe away the toothpaste using a damp cloth. Let the shoes dry in a warm spot. Combine lemon juice with cream of tartar. Mix together, adjusting the amounts, until a paste is formed. Rub the mixture onto the stain and let sit for approximately half an hour. Then, remove the mixture with a sponge and wipe with a clean cloth.

The I-9 is a medium-to-large hook that is a good place to start. Pick a medium weight yarn (look for the number "4"). Try to pick a solid, bright color to begin.

Problem: Article: Many air purifiers use non-washable HEPA filters. Turn off and unplug your appliance before accessing the filter. Check your product manual for specific instructions on how to access your appliance's filter. At least one foam or activated charcoal filter usually accompanies a non-washable HEPA filter. These accompanying filters typically need to be rinsed for two to three minutes, or until water runs clear. Towel dry your foam or activated charcoal filters, then let them air dry completely for at least 24 hours. Use your vacuum cleaner's hose with a nozzle or brush attachment to clean your non-washable HEPA filter. Run the attachment over the filter until you've removed all debris. Take care not to puncture the filter with the vacuum attachment. Reassemble your appliance after the washable filters have dried. You can wrap the HEPA filter tightly in plastic while you're waiting for the other filters to dry or during any other extended period of non-use. Some air purifiers have an electronic filter clean reminder. If yours has one, reset it after cleaning your filter.
Summary: Remove the filter from your appliance. Wash your appliance's other filters. Run a vacuum cleaner hose attachment over the filter. Reassemble the appliance.
