We know that fiberglass planters are hardy and can tolerate a fair amount of abuse. But you do have to care for it once in a while. Cleaning Your Fiberglass Planter Dirt and dust can easily accumulate on your planter over time. As such, you should make it a habit to wipe it down with mild soap dissolved in just enough warm water using a soft sponge. Be sure to thoroughly rinse off the soapy water when you're done. If you're cleaning an indoor fiberglass planter, you can use a damp cloth instead of a soft sponge. Take Care of the Little Cracks and Chips Fiberglass planters can be chipped or cracked over time. It's not really that big of a problem with this kind of planter. However, leaving these cracks open might mean water and moisture getting under the protective coating. As time passes, the protective coating chips and flakes off. Also, if your planter has some mineral buildup, be sure to remove these as soon as you spot them. The thing is, sometimes, the repair is easy. For example, you can touch up small scratches with a coat of paint. If the scratch, dent, or chip is deeper, you can just sand the area and then fill it out with epoxy before painting over the damaged part. Waxing Your Fiberglass Planter Giving your planter a coat of wax will help make it more durable, with the welcome side effect of making it look glossy and better protected from the elements. Coating it with wax will also make your planter less susceptible to dust and dirt, so you clean it less frequently. You can use products like the Star Brite Premium Marine Polish, which is formulated for fiberglass and other similar surfaces. There are also sprays that can help you protect your fiberglass planters. A product like the 303 Marine UV Protectant Spray helps prevent cracking and fading while also repelling dust, dirt, and stains without the greasy feeling. Other Tips: • Handle your fiberglass planters with care. If you need to move it around, you should first empty it and move it safely rather than push, tug, or twist the planter. • Avoid using harsh chemicals and abrasives to clean persistent dirt as these can strip the planter of its protective coating. A tough abrasive like steel wool can also leave deep scratches on your planter. • Keep them off the ground. Fiberglass planters should have feet or a platform to keep them off the ground. There is a possibility that the planter will sink if you put it on grass or dirt. This will result in the planter having problems with drainage.
