Spring has been here for more than a month, and I’m just getting to seasonal cleaning suggestions.

From Robin Wilson, described as a healthy-space designer and “ambassador” for the Asthma and Allergy Foundation of America, come the following tips:

• In the bathroom, get rid of your vinyl shower curtain, because it holds mold more easily and off-gases. Use a nylon curtain instead. Use nontoxic cleansers and always lower the toilet seat when flushing.

• For bedding, wash pillowcases once a week, pillow protectors at least once a month and replace pillows every three years. Cover your mattress with a hypoallergenic cover, wash it every two months, and make sure it is nontoxic, without formaldehyde-based fire retardants.

• Check for mold in dishwashers, under the fridge in the water pan, and in the sink and bath drains. Change water dispenser and ice maker filters.

• Wash or freeze your children’s stuffed animals to kill dust mites.

Now, from Benjamin Moore Paints, here are ways to make your house more springlike:

• Hang a mirror with a stylish frame. The mirror can fill the wall with a decorative accent while reflecting light and opening up the space.

• Declutter: Get rid of items that are weighing a space down. Collect the things that are lying around the house. Keep half of everything and invite your friends and family over for a treasure hunt through the rest.

QUESTION: My problem is foil paper on drywall. The paper is on very tight and is impossible to remove.

In a column a long time ago, you mentioned a product by Zinsser called Shieldz. Do you think that would work? I have a powder room and small bathroom with the problem. I know I could drywall, but hope it won’t be necessary.

ANSWER: Manufactured now by Rust-o-leum, Shieldz is a primer you apply to walls to make hanging wallpaper easier. It has nothing to do with removing foil paper, or removing any wallpaper for that matter.

The trick to removing wallpaper is getting whatever liquid you use for the job — warm water, vinegar, or some commercial product — behind the paper so the bond between it and the adhesive is softened enough to be broken.

Some people use razor blades or X-Acto knives. A Zinsser tool called Paper Tiger will score or puncture the paper so the liquid will find its way more easily behind it. In all situations, you have to be very careful not to be too hasty and start pulling the paper or foil off until it has loosened enough not to drag the drywall paper along with it.
